CCT Velké Popovice - yeast propagation, two-way filling, stripping and homogenization of beer using CO2.

Abstract

Inoculation of yeast culture in transferred wort facilitates its fast and thereby natural transmission from the laboratory conditions into the operational CCTs. Growth rate together with gentle fermentation rate enables acquisition of fermenting yeast free of nutrient stress in a standard way. This fact together with maintaining of yeast cells in an exponential growth phase results in even attenuation of beer. Stripping using CO2 offers an efficient tool for homogenisation of wort in CCT before fermentation or during cooling. CO2 flow enables not only to keep the circulation of beer at abnormal temperatures, but also allows the possibility to standardise contInoculation of yeast culture in transferred wort facilitates its fast and thereby natural transmission from the laboratory conditions into the operational CCTs.
