Viticulture ( Latin : vitis cultura , " vine -growing"), viniculture ( vinis cultura , " wine -growing"), or winegrowing is the cultivation and harvesting of grapes . It is a branch of the science of horticulture . While the native territory of Vitis vinifera , the common grape vine, ranges from Western Europe to the Persian shores of the Caspian Sea , the vine has demonstrated high levels of adaptability to new environments, hence viticulture can be found on every continent except Antarctica .

70-757: Napa Valley is an American Viticultural Area (AVA) located in Napa County , California . The area was established by the Bureau of Alcohol, Tobacco and Firearms (ATF) , Treasury on February 27, 1981 after reviewing the 1978 petition submitted by the Napa Valley Vintners and Napa Valley Grape Growers Association on behalf of valley vineyard owners and winemakers proposing to establish a viticultural area named "Napa Valley" as an appellation of origin in wine labeling and advertising would help consumers of wine to better identify Napa Valley wines. Napa Valley

140-399: A blind tasting format. The news of the wine competition, termed the "Judgment of Paris", was immediately published by a Time magazine article and later portrayed in the 2008 Hollywood film, Bottle Shock . The results of the momentous event established Napa's international reputation as a premier wine-producing region. A modern outbreak of phylloxera was discovered in the valley in 1983 in

210-408: A climate system where fog and cooler sea air are drawn inland through valleys, create ideal conditions for high-quality viticulture. The region's complexity extends to varying topography, sun exposure, and diverse soils, contributing to a wide array of microclimates or terroirs within a relatively small viticulture area. Napa Valley, despite its linear appearance, is a tapestry of climate influences from

280-496: A cluster. Each grape berry contains a pedicel which attaches to the rachis . The main function of the rachis is to allow the grapes to receive their water and nutrients. The pollination and fertilization of grapes results in one to four seeds within each berry. When fertilization does not occur, seedless grapes are formed, which are sought after for the production of raisins . Regardless of pollination and fertilization, most plants will produce around 100 to 200 grapes. The skin of

350-427: A few years. A viticulturist faces many hazards that can have an adverse effect on the wine produced from the grape or kill the vine itself. A green harvest is the removal of immature grape bunches, typically for the purpose of decreasing yield. The removal of the bunches while they are still green induces the vine to put all its energy into developing the remaining grapes. In theory this results in better ripening and

420-598: A fresher and more acidic harvest. In general, the average yearly temperature for most crops should average around 15 °C (59 °F) in order to achieve the highest quality in each grape. Summer: Ideal temperatures in summer average around 22 °C (72 °F). Ideal summer temperatures enable fruits to ripen. Temperature and sunshine are the most important factors in ripening. Winter: Ideal temperatures in winter average around 3 °C (37 °F). Ideal winter temperatures are necessary to allow grape vines to enter their resting phase. If temperatures fall too low,

490-409: A god. The Bible makes numerous references to wine, and grapevines, both symbolically and literally. Grapes are first mentioned when Noah grows them on his farm (Genesis 9:20–21). References to wine are made in the book of Proverbs (20:1) and the book of Isaiah (5:1–25). Deuteronomy (18:3–5, 14:22–27, 16:13–15) reports the use of wine during Jewish festivals. In Christianity wine is the symbol of

560-629: A petition is accepted as complete, the TTB may choose to seek public input on the proposal and at its sole discretion may approve the proposed AVA. Before the AVA system, wine appellations of origin in the United States were designated based on state or county boundaries. All of these appellations were grandfathered into federal regulations and may appear on wine labels as designated places of origin in lieu of an AVA, such as Sonoma County . In order for

630-436: A slope affords better drainage, obviating the possibility that the vine might sit in overly moist soil. In cooler regions of the northern hemisphere, south-facing slopes receive more hours of sunlight and are preferred; in warmer climes , north-facing slopes are preferred. In the southern hemisphere, these orientations are reversed. Quality soil is important to allow plants to have better root systems. The growth and health of

700-402: A slope can receive a greater intensity of the sun's rays, with sunshine falling on an angle perpendicular to the hillside. In flatter terrain, the intensity of the sunlight is diluted as it spreads out across a wider surface area. Small slopes that are elevated above surrounding ground are the best and safest places for crops, because these small elevations are less prone to frost. Additionally,

770-497: A uniquely preferred environment for ideal growing. Because climates vary from region to region, selecting the best strain is an important decision in grape cultivation. Additionally, because climatic factors such as temperature and rain can be unpredictable and uncontrollable, each year will produce unique qualities and yields of grapes. Wine grapes are also especially susceptible to climate change and temperature variation. Grape vines need approximately 1300–1500 hours of sunshine during

840-599: A very popular tourist destination in California. As of 2024, within Napa Valley AVA, there are seventeen sub-AVAs: American Viticultural Area An American Viticultural Area ( AVA ) is a designated wine grape -growing region in the United States , providing an official appellation for the mutual benefit of wineries and consumers. Winemakers frequently want their consumers to know about

910-479: A vine can be affected if the soil quality is poor. Different grape species prefer various soil conditions, although there are general quality factors. Favorable soil conditions include: aeration , loose texture, good drainage and moderate fertility. Drainage factors are cited as the most important soil characteristic to affect grape vine growth. When root growth is restricted due to bad soil, vine growth and fruit yields lessen and plant survival rates can dip to only

980-693: A vineyard planted with AxR1 rootstock. Many growers seized upon this outbreak as an opportunity to switch to varieties that were better suited to the climate and soil. By the late 1990s about 75% of the affected vineyards had been replanted with phylloxera resistant rootstock. The growers in the region have since channeled their energy to battle the Glassy-winged sharpshooter , a non-native pest that carries Pierce's disease . A trend of larger national and international companies like E & J Gallo Winery , Diageo and Constellation Brands buying smaller wineries, vineyards and brands began to gain momentum in

1050-401: A wine to be labeled with a state or county appellation, at least 75% of the grapes used to make the wine must have been grown within the boundary of the appellation, and the wine must be fully finished within the state in which the appellation is located. Some states have more stringent rules, such as California , which requires 100% of the grapes used to make the wine be from California and that

1120-536: Is closely related to the history of wine , with evidence that humans cultivated wild grapes to make wine as far back as the Neolithic period. Evidence suggests that some of the earliest domestication of Vitis vinifera occurred in the area of the modern countries Georgia and Armenia . The oldest-known winery was discovered in the "Areni-1" cave in Vayots Dzor , Armenia . Dated to c.  4100 BC,

1190-742: Is commonly cited as the Napa Valley's first winery. Captain Gustave Niebaum established Inglenook Winery in 1879 near the village of Rutherford. This was the first Bordeaux style winery in the US. Inglenook wines won gold medals at the 1889 World's Fair in Paris . In 1868 H. W. Crabb bought land near Oakville close to the Napa River . Crabb established a vineyard and winery named To Kalon, and by 1877 had planted 130 acres (0.5 km) and

1260-458: Is considered one of the premier wine regions in the world. Historical records of viticulture in the region date back to the nineteenth century, but the modern premium wine production grew in the 1960s. The combination of Mediterranean climate , geography and geology of the region are conducive to growing quality wine grapes. George C. Yount was the first vineyardist on record in Napa Valley planting his vines in 1838. John Patchett established

1330-486: Is not always the case. See map on the right showing the outline of the Paso Robles AVA , California's largest in total area, and the eleven distinct AVAs contained within it. In 2018, the second session of the 115th Congress recognized the contribution of American Viticultural Areas to the economy. The Blunt-Merkley Resolution passed unanimously. It noted that an AVA allows vintners to describe more accurately

1400-587: Is now an major international enotourism destination. The valley floor is flanked by the Mayacamas Range on the western and northern sides and the Vaca Mountains on the eastern side. Several smaller valleys exist within these two ranges. The floor of the main valley gradually rises from sea level at the southern end to 362 feet (110 m) above sea level at the northern end in Calistoga at

1470-403: Is provided by cuneiform sources (ancient writing on clay tablets), plant remains, historical geography, and archaeological excavations. The remnants of ancient wine jars have been used to determine the culture of wine consumption and cultivated grape species. In addition to winemaking, grapes have been grown for the production of raisins . The earliest act of cultivation appears to have been

1540-530: The Cole Ranch AVA in Mendocino County , California, at only 60 acres (24 ha). The Augusta AVA , which occupies the area around the town of Augusta, Missouri , was the first recognized AVA, gaining the status on June 20, 1980. There are currently 276 AVAs spread across 34 states, with over half (154) in California. An AVA may be located within one or more larger AVAs. For example,

1610-549: The Côte-d'Or , the monks divided the land into separate vineyards, many of which still exist today, like Montrachet and La Romanée . In Greek mythology , the demigod Dionysus ( Bacchus in Roman mythology ), son of Zeus , invented the grapevine and the winepress. When his closest satyr friend died trying to bring him a vine Dionysus deemed important, Dionysus forced the vine to bear fruit. His fame spread, and he finally became

1680-541: The Golden Gate International Exposition to visit the winery using promotional maps printed with the phrase "All roads lead to Beringer" in 1939. The winery also invited Hollywood stars including Clark Gable , Charles Laughton and Carole Lombard to visit. These early promotions are considered to be the birth of wine-based tourism that is now a large part of the economy of Napa Valley today. Brother Timothy of Christian Brothers winery

1750-523: The Last Supper , representing the blood of Christ . It is mentioned several times in the New Testament . We have the parable of the kingdom of heaven likened to the father starting to engage laborers for his vineyard. The vine is used as symbol of Jesus Christ based on his own statement, "I am the true vine (John 15:1)." In that sense, a vine is placed as sole symbol on the tomb of Constantine

1820-721: The Mediterranean began to emerge from barbarism when they learnt to cultivate the olive and the vine. Thucydides was most likely referencing the time between 3000 BC and 2000 BC, when viticulture emerged in force in Asia Minor , Greece , and the Cyclades Islands of the Aegean Sea . During this period, grape cultivation developed from an aspect of local consumption to an important component of international economies and trade . From 1200 BC to 900 BC,

1890-577: The Middle Ages . Around this time, an early system of Metayage emerged in France with laborers ( Prendeur ) working the vineyards under contractual agreements with the landowners ( Bailleur ). In most cases, the prendeurs were given flexibility in selecting their crop and developing their own vineyard practice. In northern Europe, the weather and climate posed difficulties for grape cultivation, so certain species were selected that better suited

1960-762: The Phoenicians developed viticulture practices that were later used in Carthage . Around 500 BC, the Carthaginian writer Mago recorded such practices in a two-volume work that was one of the few artifacts to survive the Roman destruction of Carthage during the Third Punic War . The Roman statesman Cato the Elder was influenced by these texts, and around 160 BC he wrote De Agricultura , which expounded on Roman viticulture and agriculture. Around 65 AD,

2030-786: The Repeal of Prohibition . The science teacher was a fast learner and soon established Christian Brothers as one of the leading brands in the state's budding wine industry. Brother Timothy's smiling face in advertisements and promotional materials became one of the most familiar images for wine consumers across the country. Following the Second World War , the wine industry in Napa began to thrive again. In 1965, Napa Valley icon Robert Mondavi broke away from his family's Charles Krug estate to found his own winemaking operation in Oakville . It

2100-660: The Santa Clara Valley AVA and Livermore Valley AVA are located within the boundaries of the San Francisco Bay AVA , which is itself located within the Central Coast AVA . In such cases, the wine may be labeled with any of the relevant AVAs, but winemakers generally label wines with the most specific AVA allowed for each wine. Smaller AVAs are often perceived to be associated with smaller production and higher quality wines, though this

2170-427: The growing season and around 690 millimetres (27 in) of rainfall throughout the year in order to produce grapes suitable for winemaking. In ideal circumstances, the vine will receive most of the rainfall during the winter and spring months: rain at harvesttime can create many hazards, such as fungal diseases and berry splitting. The optimum weather during the growing season is a long, warm summer that allows

2240-698: The state where the AVA is located. The boundaries of AVAs are defined by the Tax and Trade Bureau (TTB), a component of the United States Department of the Treasury . The TTB defines AVAs at the request of wineries and other petitioners . Prior to the TTB's creation in 2003, the Treasury’s Bureau of Alcohol, Tobacco and Firearms (ATF) received and handled petitions for viticultural areas, wine production and labeling. Section 4.25(e)(2) of

2310-527: The Great . The vast majority of the world's wine-producing regions are found between the temperate latitudes of 30° and 50° in each hemisphere . Within these bands, the annual mean temperatures are between 10 and 20 °C (50 and 68 °F). The presence of large bodies of water and mountain ranges can have positive effects on the climate and vines. Nearby lakes and rivers can serve as protection for drastic temperature drops at night by releasing

2380-598: The Napa Valley's first commercial vineyard in 1858. In 1861 Charles Krug established another of Napa Valley's first commercial wineries in St. Helena . By 1880, its first great period of prominence, the Napa Valley had 443 vineyards with a thousand or more vines each. Of these major holdings, 72 were in the Calistoga district, 126 were in Napa City and 245 in the St. Helena area. Viticulture in Napa suffered several setbacks in

2450-472: The Roman writer Columella produced the most detailed work on Roman viticulture in his twelve-volume text De Re Rustica . Columella's work is one of the earliest to detail trellis systems for raising vines off the ground. Columella advocated the use of stakes versus the previously accepted practice of training vines to grow up along tree trunks. The benefits of using stakes over trees was largely to minimize

2520-512: The adjacent Vaca and Mayacamas mountain ranges, alongside varied lithologies influencing vineyard substrates. This geographical diversity, coupled with the Mediterranean climate characterized by hot, dry summers and cool, wet winters, impacts grape growing in the Napa Valley. Rainfall distribution and the daily summer fog, which typically shrouds the valley until mid-morning, vary across the region, affecting grape variety and quality. However,

2590-638: The area. Of those original wineries, several still exist in the valley today including Beaulieu , Beringer , Charles Krug , Chateau Montelena , Far Niente , Mayacamas , Markham Vineyards , and Schramsberg Vineyards . Viticulture in Napa suffered several setbacks in the late 19th and early 20th centuries. The Phylloxera louse killed many of the vines throughout the valley. Prohibition , enacted in 1920, caused many wineries to shut down. A few remained open with agreements to produce sacramental wine . Growers who elected to keep their vines planted sold their crops to home winemakers. The Great Depression slowed

2660-493: The base of Mount Saint Helena . The Oakville and Rutherford viticultural areas lie within a geographical area known as the Rutherford Bench in the center of the valley floor. The soil in the southern end of the valley consists mainly of sediments deposited by earlier advances and retreats of San Pablo Bay while the soil at the northern end of the valley contains a large volume of volcanic lava and ash. Several of

2730-399: The concept of thinning or sacrificing part of the grape crop, i.e. green harvesting, with the aim of improving the quality of the remaining grapes, predates modern critics, the practice has increased in recent times in vineyards found in California and areas where the grapes grow easily. (McCoy) A field blend is a wine that is produced from two or more different grape varieties interplanted in

2800-478: The couple around 1,000 acres (2 sq mi) of land, which Rutherford dedicated to viticulture. Other pioneers followed in the 1840s and 1850s, by which time vineyards were established in and around Napa City and up the length of the valley to Calistoga . Commercial production began in 1858, with John Patchett selling wine for $ 2 per gallon. His wine cellar, built in 1859, narrowly predates that established in 1861 in St. Helena by Charles Krug , although this

2870-469: The crops can be injured. Spring and Fall: Spring and fall are critical seasons for grape development, because the plants are susceptible to frost damage, which can injure the fruiting buds. Wet weather in spring can increase the odds of mildew formation. To prevent mildew, some farms introduce devices such as heaters or large fans in vineyards. However, such solutions can be costly. Hillsides and slopes are preferred over flatter terrain: vines growing on

2940-623: The dangers associated with climbing trees, which was necessary to prune the dense foliage in order to give the vines sunlight, and later to harvest them. Roman expansion across Western Europe brought Roman viticulture to the areas that would become some of the world's best-known winegrowing regions : the Spanish Rioja , the German Mosel , and the French Bordeaux , Burgundy and Rhône . Roman viticulturists were among

3010-448: The development of more numerous and mature flavour compounds. In the absence of a green harvest, a healthy, vigorous vine can produce dilute, unripe grapes. In Europe, many appellations restrict the yield permitted from a given area, so there is even more incentive to perform green harvesting when presented with excess crop. Often, the excess must be sold for a pittance and used for industrial alcohol production rather than wine. While

3080-453: The early part of the 21st century. Today Napa Valley features more than 450 wineries that grow grape varieties including Cabernet Sauvignon , Chardonnay , Pinot noir , Merlot , Zinfandel , among others. While winemakers may produce wines from specific AVAs within the valley, many wines are made as a blend from grapes grown on the valley floor and the surrounding hillsides. More than 4.5 million people visit Napa Valley each year, making it

3150-596: The environment. Most vineyards grew white varieties of grape, which are more resistant to the damp and cold climates. A few species of red grape, such as the Pinot Noir , were also introduced. Les Très Riches Heures du duc de Berry dates back to 1416 and depicts horticulture and viticulture in France. The images illustrate peasants bending down to prune grapes from vines behind castle walls. Additional illustrations depict grape vines being harvested, with each vine being cut to three spurs around knee height. Many of

3220-517: The favoring of hermaphroditic members of the Vitis vinifera species over the barren male vines and the female vines, which were dependent on a nearby male for pollination . With the ability to pollinate itself, over time the hermaphroditic vines were able to sire offspring that were consistently hermaphroditic. At the end of the 5th century BC, the Greek historian Thucydides wrote: The people of

3290-655: The field blend is an anachronism, and almost all wines are assembled by blending from smaller, individual lots. However, in California some of the oldest (and lowest-yielding) Zinfandel comes from vineyards that are field-blended. Ridge Vineyards owns the Lytton Springs vineyards in Sonoma County, which were planted from 1900 to 1905 in what Ridge calls "a traditional field blend of about seventy percent Zinfandel, twenty percent Petite Sirah , and ten percent Grenache and Carignan." Gemischter Satz ( Mixed set )

3360-459: The first to identify steep hillsides as one of the better locations to plant vines, because cool air runs downhill and gathers at the bottom of valleys. While some cool air is beneficial, too much can rob the vine of the heat it needs for photosynthesis , and in winter it increases the risk of frost . Catholic monks (particularly the Cistercians ) were the most prominent viticulturists of

3430-410: The geographic pedigree of their wines, as wines from a particular area can possess distinctive characteristics. Consumers often seek out wines from specific AVAs, and certain wines of particular pedigrees can claim premium prices and loyal customers. If a wine is labeled with an AVA, at least 85% of the grapes that make up the wine must have been grown in the AVA, and the wine must be fully finished within

3500-447: The grape accounts for 5 to 20% of the total weight of a grape depending on the variety. When grape skin ripens, it contains the majority of the aromatic substances and tannin . These factors become important in winemaking for methods including color extraction or aroma dissolution. Although the skin contains the majority of the tannin, small percentages can be found throughout the grape and during all of its developmental stages. However,

3570-428: The grapes the opportunity to ripen fully and to develop a balance between the levels of acids and sugars in the grape. Hot and sunny climates have a frost-free growing season of 200 days or more. These climates allow grapes to ripen faster with higher sugar levels and lower acidity. Cooler climates have a frost-free growing season of around 150–160 days. Cooler seasons force the grapes to ripen earlier, which produces

3640-469: The heat that the water has stored during the day to warm the vines. Structure of the grape vine There are many different important parts of the grape vine. Starting from the bottom and moving up there are the Fender roots, then above that are the roots . These help with anchorage, absorption and food storage. Then there is the trunk which branches out into arms. These help support conduction. Higher up are

3710-632: The late 19th and early 20th centuries, including an outbreak of the vine disease phylloxera , national enactment of Prohibition , and the Great Depression . The modern wine industry in Napa Valley gradually recovered and gained immediate recognition by the surprising outcome at the Paris Wine Tasting of 1976 where Napa Valley vintages scored top honors against primer French wines establishing its place as an international viticulture producer bettering Old World wine regions. Napa Valley

3780-545: The node, inter node, leaves, cluster (of grapes) and the tendril . The tendril helps with support of the plant. The grape is classified as a berry . On the vine, grapes are organized through systems known as clusters. Grape clusters can vary in compactness which can result in long clusters (resulting in the grapes spreading out) or short clusters (resulting in grapes packed together). In some grape species, clusters ripen collectively, which allows them to be harvested together. For others, grapes may ripen individually within

3850-587: The origin of their wine, while helping vintners to build and enhance the reputation and value of the wines produced. AVAs also allow consumers to attribute a given quality, reputation, or other characteristic to a wine made from grapes grown in an AVA. AVAs also help consumers identify what they purchase. Vineyardist The duties of a viticulturist include monitoring and controlling pests and diseases , fertilizing , irrigation , canopy management , monitoring fruit development and characteristics , deciding when to harvest , and vine pruning during

3920-456: The potential impacts of climate change pose new challenges: rising global temperatures and possible disruptions to the cooling effect could alter the conditions that have historically favored premium grape growing in Napa Valley. Early settler and pioneer vineyardist George C. Yount is generally credited as the first to plant grapevines in Napa Valley in 1838. In 1864, on the marriage of one of his granddaughters to Thomas Rutherford, Yount gave

3990-400: The regulations (27 C.F.R. § 4.25(e)(2)) outlines the procedure for proposing an AVA and provides that any interested party may petition the TTB to establish a grape-growing region as an AVA. Section 9.12 of the TTB regulations (27 C.F.R. § 9.12) prescribes the standards for petitions for the establishment or modification of AVAs. Petitions to establish an AVA must include the following: Once

4060-540: The rich landowners who wanted higher quality wines and the peasant laborers whose livelihood depended on the quantity of wine they could sell. The Riesling is the famous example for higher quality of wine. In 1435 Count John IV. of Katzenelnbogen started this successful tradition. In Burgundy , the Cistercian monks developed the concept of cru vineyards as homogeneous pieces of land that consistently produce wines each vintage that are similar. In areas like

4130-516: The same vineyard. In the days before precise varietal identification, let alone rigorous clonal selection , a vineyard might be planted by taking cuttings from another vineyard and therefore approximately copying its genetic makeup. This meant that one vine could be Zinfandel and the next Carignan . When making wine with little equipment to spare for separate vinification of different varieties, field blends allowed effortless, though inflexible, blending. Fermentation tanks are now cheap enough that

4200-526: The site contained a wine press, fermentation vats, jars, and cups. Archaeologists also found V. vinifera seeds and vines. Commenting on the importance of the find, McGovern said, "The fact that winemaking was already so well developed in 4000 BC suggests that the technology probably goes back much earlier." There is also evidence of grape domestication in the Near East in the early Bronze Age , around 3200 BC. Evidence of ancient viticulture

4270-427: The small hills that emerge from the middle of the valley floor near Yountville are indicators of the region's volcanic past. Several mesoclimates exist within the area due to various weather and geographical influences. The open southern end of the valley floor is cooler during the growing season due to the proximity of San Pablo Bay while the sheltered, closed northern end is often much warmer. The eastern side of

4340-427: The tannin's most important role is during the grape's ripening stage as its function is to formulate color and body shape. Although many factors can affect the overall quality of a grape vine, the three most important are climate, slope , and soil , often collectively referred to as the terroir . Climate is the most significant external factor in determining a grape's inherent qualities. Each grape variety has

4410-477: The valley tends to be more arid due to the rain shadow caused by the western mountains and hills. Napa Valley's climate and geography are shaped by a unique cooling effect, crucial for premium grape growing. Originating from a cold ocean current from Alaska, this effect involves fog formation and cool air influx from the Pacific, offset by warmer air rising from California's Central Valley. This dynamic results in

4480-497: The viticultural practices developed in this time period would become staples of European viticulture until the 18th century. Varietals were studied more intently to see which vines were the most suitable for a particular area. Around this time, an early concept of terroir emerged as wines from particular places began to develop a reputation for uniqueness. The concept of pruning for quality over quantity emerged, mainly through Cistercian labors, though it would create conflict between

4550-699: The wine be fully finished within the state. Washington requires 95% of the grapes in a Washington wine be grown in Washington, although notably the Columbia Valley AVA , Columbia Gorge AVA , and Walla Walla Valley AVA are shared with Oregon. AVAs vary widely in size, ranging from the Upper Mississippi River Valley AVA , at more than 19 million acres (29,900 square miles (77,000 km )) across four states ( Illinois , Iowa , Minnesota , and Wisconsin ), to

4620-526: The wine business further. These events stalled the growth of the wine industry in Napa County, California for years. André Tchelistcheff is generally credited with ushering in the modern era of winemaking in California. Beaulieu hired Tchelisticheff in 1938. He introduced several techniques and procedures to the region, such as aging wine in small French Oak barrels, cold fermentation, vineyard frost prevention, and malolactic fermentation . Following Prohibition , Beringer Vineyards invited attendees of

4690-498: The winter months. Viticulturists are often intimately involved with winemakers, because vineyard management and the resulting grape characteristics provide the basis from which winemaking can begin. A great number of varieties are now approved in the European Union as true grapes for winegrowing and viticulture. The earliest evidence of grape vine cultivation and winemaking dates back 8,000 years. The history of viticulture

4760-615: Was also instrumental in establishing the modern wine industry in Napa. After an earlier career as a teacher, he transferred to the order's Mont La Salle located on Mount Veeder in the Mayacamas Mountains northwest of Napa in 1935 to become the wine chemist for the order's expanding wine operations. Christian Brothers had grown grapes and made sacramental wine in Benicia, California during Prohibition, but decided to branch out into commercial production of wine and brandy after

4830-472: Was producing 50,000 US gallons of wine per year. Crabb experimented with over 400 grape varieties to find the types best suited for the area. By 1880, its first great period of prominence, the Napa Valley had 443 vineyards with a thousand or more vines each. Of these major holdings, 72 were in the Calistoga district, 126 were in Napa City and 245 in the St. Helena area. At the end of the nineteenth century, there were more than one hundred and forty wineries in

4900-562: Was the first new large scale winery to be established in the valley since prohibition and included the original To Kalon land. After this, the number of wineries in the valley grew rapidly, as did the region's reputation. During the Bicentennial , the region gained international recognition from the Paris Wine Tasting of 1976 when featured Napa Valley Chardonnay and Cabernet Sauvignon vintages ranked #1 honors, scored by renown French oenophiles , besting several famous French labels in
