Opened fermentation tanks / Uncovered fermentors
Traditional Czech non-pressure fermentors for the primary beer fermentation necessary to production of typical lager beers
A technology of the primary fermentation in open fermentation vats in a dedicated fermentation room (Spilka) is typical mainly for production of traditional Czech lagers like Pilsner beer.
The construction of the uncovered fermentors allows especially convenient collection of foam from the dead yeast on a surface of wort and its full removing in the last stage of the primary fermentation which is a prerequisite for making a quality bottom fermented beer of traditional taste. This type of fermentors is typical mainly for Czech craft breweries.
A craft brewery equipped with the technology of opened fermentors has an opportunity to show the beer production in its different phases . Who ever visited a traditional Czech craft brewery as a tourist, in his mind remains the memory of a bathtub full of young beer, which is covered by a layer of foam of interesting structure and colors. Looking at beer at the stage of primary fermentation is simply fascinating, and that is the most important for marketing of the small brewery.
