Karlsbad-style coffee maker

Special drip coffee maker utilizing a slitted through-glazed porcelain filter

A variant of the category of French drip coffee pots is the group of "Bohemian" coffee pots, manual zero-bypass flat bottom coffee makers made out of porcelain only, including Karlsbad coffee makers, Bayreuth coffee makers, 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 cross-slitted strainer made from through-glazed porcelain as well as a water spreader with six 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 is called a Karlsbader. In Vienna, the Kleiner Schwarzer, a black coffee without milk or sugar, was often prepared in Karlsbad coffee makers as well.
