26-466: Piave may refer to: Piave (river) , in north Italy Piave cheese , an Italian cow's milk cheese that is named after the Piave river Francesco Maria Piave (1810–1876), Italian librettist, journalist and theater impresario See also [ edit ] Battle of Piave River (disambiguation) 10th Infantry Division "Piave" Topics referred to by

52-723: A percentage of total mass . The alc/vol value of a beverage is always higher than the ABW. Because ABW measures the proportion of the drink's mass which is alcohol, while alc/vol is the proportion of the drink's volume which is alcohol, the two values are in the same proportion as the drink's density is with the density of alcohol. Therefore, one can use the following equation to convert between ABV and ABW: ABV = ABW × density of beverage density of alcohol {\displaystyle {\text{ABV}}={\text{ABW}}\times {\frac {\text{density of beverage}}{\text{density of alcohol}}}} At relatively low alc/vol,

78-473: A 50% v/v ethanol solution, 50 mL of ethanol and 50 mL of water could be mixed but the resulting volume of solution will measure less than 100 mL due to the change of volume on mixing, and will contain a higher concentration of ethanol. The difference is not large, with the maximum difference being less than 2.5%, and less than 0.5% difference for concentrations under 20%. Some drinks have requirements of alcoholic content in order to be certified as

104-415: A certain alcohol brand or label. Low-alcohol beers (<0.5) are considered in some countries such as Iran as permitted (or "halal" under Muslim vocabulary) despite alcohol being banned. However, the level of alcohol-free beers is typically the lowest commercially sold 0.05. It is near impossible for a healthy person to become intoxicated drinking low-alcohol drinks. The low concentration severely limits

130-457: A halt as the alcohol produced becomes too concentrated for the yeast to tolerate, defining an upper limit of alc/vol for non-distilled alcoholic drinks. The typical tolerance for beer yeasts is at 8–12%, while wine yeasts typically range from 14–18%, with speciality ones reaching 20% alc/vol. Any higher would require distillation, producing liquor . Details about typical amounts of alcohol contained in various beverages can be found in

156-666: A wine labelled Verduzzo ). For wines to qualify for DOC labelling the stated variety, they must make up at least 95% of the blend from grapes that are harvested within a maximum yield restriction—11 tonnes / hectare for the Cabernets, Verduzzos and Friulano varieties, 12 tonnes/ha for the Pinots, 13 tonnes/ha for Merlot and 14 tonnes/ha for Raboso. The finished wines also must meet a minimum alcohol level —11.5% for all varieties except Merlot and Friulano which only need to reach 11% alcohol by volume. A separate riserva bottling for

182-420: Is 0.78945 g/mL (0.82353 oz/US fl oz; 0.79122 oz/imp fl oz; 0.45633 oz/cu in). The alc/vol standard is used worldwide. The International Organization of Legal Metrology has tables of density of water–ethanol mixtures at different concentrations and temperatures. In some countries, e.g. France , alcohol by volume is often referred to as degrees Gay-Lussac (after

208-441: Is 1.05 times that of water, it has a specific gravity of 1.05. In UK brewing usage, it is customary to regard the reference value for water to be 1000, so the specific gravity of the same example beer would be quoted as 1050. The formulas here assume that the former definition is used for specific gravity. During ethanol fermentation the yeast converts one mole of sugar into two moles of alcohol. A general formula for calculating

234-457: Is a standard measure of the volume of alcohol contained in a given volume of an alcoholic beverage , expressed as a volume percent . It is defined as the number of millilitres (mL) of pure ethanol present in 100 mL (3.5 imp fl oz; 3.4 US fl oz) of solution at 20 °C (68 °F). The number of millilitres of pure ethanol is the mass of the ethanol divided by its density at 20 °C (68 °F), which

In 1918, during World War I , it was the scene of Battle of the Piave River , the last major Austro-Hungarian attack on the Italian Front, which failed. The Battle of

286-642: Is sugar by weight and SG is relative density. SG can be measured using an hydrometer and Brix can be calculated from SG. One of the accurate formulas for calculating Brix from SG is: By substituting Brix in the SBV formula above, we get a formula for calculating SBV from SG only: The general calculation steps involves calculation of SBV at the start and the end of fermentation: Advanced formula derived from Carl Balling empirical formulas. The formula compensates for changes in SG with changes in alcohol concentration and for

312-1225: Is the specific gravity when fermentation ends, Plato start is the sugar by weight when fermentation begins, Plato final is the sugar by weight when fermentation ends. Brix can be used insted of Plato as they are nearly identical. The simplest method for wine has been described by English author Cyril Berry : ABV ≈ 136 × ( Starting SG − Final SG ) {\displaystyle {\text{ABV}}\approx 136\times \left({\text{Starting SG}}-{\text{Final SG}}\right)} One calculation for beer is: ABV ≈ 131 × ( Starting SG − Final SG ) {\displaystyle {\text{ABV}}\approx 131\times \left({\text{Starting SG}}-{\text{Final SG}}\right)} For higher ABV above 6% many brewers use this formula: alc/vol ≈ 105 0.79 × ( Starting SG − Final SG Final SG ) {\displaystyle {\text{alc/vol}}\approx {\frac {105}{0.79}}\times \left({\frac {{\text{Starting SG}}-{\text{Final SG}}}{\text{Final SG}}}\right)} Another way of specifying

338-400: Is used to measure the change in specific gravity (SG) of the solution before and after fermentation. The volume of alcohol in the solution can then be estimated. There are a number of empirical formulae which brewers and winemakers use to estimate the alcohol content of the liquor made. Specific gravity is the density of a liquid relative to that of water, i.e., if the density of the liquid

364-486: Is usually found in non-polar mixtures. Thus, alc/vol is not the same as volume fraction expressed as a percentage. Volume fraction, which is widely used in chemistry (commonly denoted as v/v), is defined as the volume of a particular component divided by the sum of all components in the mixture when they are measured separately. For example, to make 100 mL of 50% alc/vol ethanol solution, water would be added to 50 mL of ethanol to make up exactly 100 mL. Whereas to make

390-730: The United Kingdom , proof is 1.75 times the number (expressed as a percentage). For example, 40% alc/vol is 80 proof in the US and 70 proof in the UK. However, since 1980, alcohol proof in the UK has been replaced by alc/vol as a measure of alcohol content, avoiding confusion between the UK and US proof standards. In the United States, Arkansas , Kansas , Mississippi , South Carolina , and Tennessee regulate and tax alcoholic beverages according to alcohol by weight ( ABW ), expressed as

416-602: The Veneto wine region known as the Piave DOC. Here both red and white wine are produced, mostly as varietal wines, with Merlot being the dominant grape of the region. Among the other grapes grown in the region are Cabernet Sauvignon , Cabernet franc (which can be made separately or together as a wine labelled Cabernet ), Pinot blanc , Pinot grigio , Pinot nero , Raboso , Friulano , Verduzzo Trevigiano and Verduzzo Friulano (which can be made separately or together as

442-608: The French chemist Joseph Louis Gay-Lussac ), although there is a slight difference since the Gay-Lussac convention uses the International Standard Atmosphere value for temperature, 15 °C (59 °F). Mixing two solutions of alcohol of different strengths usually causes a change in volume. Mixing pure water with a solution less than 24% by mass causes a slight increase in total volume, whereas

468-666: The Piave River was a decisive battle of World War I on the Italian Front. In Italy the river is thus called Fiume Sacro alla Patria (Sacred River of the Homeland) and is mentioned in the patriotic song " La leggenda del Piave ". It was eventually followed by the Battle of Vittorio Veneto later that year. North of the city of Venice along the Piave Valley is the Denominazione di origine controllata (DOC) zone that makes up

494-536: The amount of alcohol content is alcohol proof , which in the United States is twice the alcohol-by-volume (alc/vol) number. This may lead to confusion over similar products bought in varying regions that have different names on country-specific labels. For example, Stroh rum that is 80% ABV is advertised and labeled as Stroh 80 when sold in Europe, but is named Stroh 160 when sold in the United States. In

520-547: The articles about them. (most juices do not have alcohol but orange or grape [the highest here] may have some from early fermentation) Under 2.5% in Finland, and 2.25% in Sweden, however. During the production of wine and beer, yeast is added to a sugary solution. During fermentation, the yeasts consume the sugars and produce alcohol. The density of sugar in water is greater than the density of alcohol in water. A hydrometer

546-584: The fact that not all sugar is converted into alcohol. All values are measured at 20 degree C.

572-441: The mixing of two solutions above 24% causes a decrease in volume. The phenomenon of volume changes due to mixing dissimilar solutions is called " partial molar volume ". Water and ethanol are both polar solvents. When water is added to ethanol, the smaller water molecules are attracted to the ethanol's hydroxyl group, and each molecule alters the polarity field of the other. The attraction allows closer spacing between molecules than

598-438: The rate of intake, which is easily dispatched by human metabolism. Quickly drinking 1.5 L of 0.4% alc/vol beer in an hour resulted in a maximum of 0.0056% BAC in a study of German volunteers. Healthy human kidneys can only excrete 0.8–1.0 L of water per hour, making water intoxication likely to set in before any alcoholic intoxication. The process of ethanol fermentation will slow down and eventually come to

624-543: The red wine varieties is permitted provided the wine is aged at least two years prior to release and attain a minimum alcohol level of at least 12.5%.
