16-544: A variant of the category of French drip coffee pots is the group of so-called Bohemian coffee pots , manual zero-bypass flat bottom coffee makers made out of porcelain only, including Karlsbad coffee makers (1878), Bayreuth coffee makers (2007), the Walküre cup filter (2010) and the Walküre aroma-pot (2015). In contrast to French drip coffee pots, they all use a special double-layered conically cross-slitted strainer made from through- glazed porcelain as well as
32-409: A coffee strainer/filter, a water spreader/distributor, and a lid) all made out of porcelain, and they exist in a number of different shapes of unknown origin. The original shape appears to have been a cylindrical filter with two squarish handles combined with a ball-shaped pot. Another early style featured a somewhat trapezoid shape known as neukonisch ( ' neoconic ' ). In 1910, SPM incorporated
48-614: A double-layered cross-slitted filter construction similar to that found in Karlsbad coffee makers, but deliberately with a much coarser grid, with a large air gap between the layers, and using ceramics instead of porcelain. Around 1900, the Staatliche Porzellanmanufaktur Meißen of Meißen , Germany, manufactured cup filters utilizing a double-layered radially slitted porcelain filter construction much coarser than in Karlsbad coffee makers. Since 1926,

The devices were manufactured by Villeroy & Boch for him. While the permanent filter in early of his devices still featured round drilled holes like in French drip coffee makers, later units used
80-530: A water spreader with six (or, in the larger models, more) large round holes to ensure an even water distribution and reduce the agitation of the coffee bed , a method sometimes also called cake filtration . In particular before World War I , but still up to the advent of the Espresso machine in the 1950s, they were very popular in the Viennese coffee house culture . The special kind of drip coffee they produce

In Vienna, the Kleiner Schwarzer (confusingly also called Mokka or Piccolo ), a black coffee without milk or sugar, was often prepared in Karlsbad coffee makers as well, hence they were sometimes incorrectly also called Vienna coffee-making machines . Once manufactured by many porcelain manufacturers, demand gradually dropped and eventually production stopped when electrical coffee makers became more and more common, so that Karlsbad coffee makers were only available on

However, whilst they are zero-bypass flat-bottom French drip coffee pots with permanent filters , they too cannot be counted as Karlsbad-style coffee makers because they do not feature a cross-slitted double-layered filter sieve and also because they are not made out of porcelain.

However, experiencing a renaissance since about the millennium as part of the so-called third-wave of coffee one manufacturer restarted production of them.

As a product of the fin de siècle the original so-called Karlsbader Kaffeemaschine ( ' Karlsbad coffee maker ' )
144-447: The 1880s, Max Thürmer, a coffee roaster of Dresden , Germany, founded in 1879, advertised Karlsbad coffee and somewhat later also coffee makers (of unknown type) in various newspapers. In the early 1900s, he marketed his own invention of a manual coffee maker (the so-called Kaffeeaufgußkanne Max Thürmer ), which, from its outer appearance, looked quite similar to cylindrical Karlsbad coffee makers but featured an air-tight joint (through

Since c. 1952 (and up into the 1970s) the Neuerer Porzellanfabrik in Oberkotzau , Germany, the successor of Porzellanfabrik Greiner & Herda, manufactured coffee percolators named Aromator , which featured double-layered cross-slitted porcelain filters similar to those used in Karlsbad coffee makers, and thus not requiring any paper filter rings . Modern manual coffee makers sometimes associated with Karlsbad-style coffee makers include Coffee Consulate's intense extraction cup filter RS16 GlasFilter by Steffen Schwarz (2015) and

#1732783916862192-462: The idea to combine steeping with drip-filtering was also utilized by Berlin -based coffee roaster Carl Artur Büttner in his invention of a manual coffee maker. While his construction was considerably different, it also featured a valving mechanism (through a rotatable saucer ), a through-glazed porcelain filter with triangularly-arranged slits and with an air space below. These so-called "System Büttner" coffee makers were available up into, at least,

However, due to its non-symmetrical design it may be difficult to handle for left-handers . It has been available in two sizes (350 ml and 700 ml) produced by Walküre up to 2019, and since 2020 by Friesland (400 ml and 700 ml). As of 2020, Friesland

This design was copied by other porcelain manufacturers. Over the years it was available in various sizes ranging from 250 ml to 2.25 litre. In 2007, the so-called Bayreuth coffee makers were created by designer Daniel Eltner for Walküre. A somewhat Bauhaus -reminiscing slick modernized style (form 699) following

Producing lithophanes , the company, which was founded in 1793/1794, already had experience manufacturing very thin and fragile porcelain for decades.
