Why choose the open fermentation method for a beer fermentation process ?

The traditional Czech brewery cellar technology is based on historically proven method of slow fermentation of wort in opened fermentation vats and the maturation of beer in closed lager-tanks at moderate overpressure. In this manner, in Central Europe, beer has been manufactured for at least 150 years.

Although in the past 50 years, the traditional method of slow fermentation of the beer was usual, in many modern breweries this method was replaced by the more efficient concept of a brewery cellar, which is the production of beer provided in closed cylindrically-conical tanks. But in many small and medium-size breweries lately there is again a shift to a proven classic open fermentation technology.

The concept of a brewery cellar with cylindrical-conical tanks instead of opened fermentation vats has distinct advantages that make this system particularly preferred for large breweries. In contrast the classical concept has several essential characteristics, that make it particularly popular alternative for microbreweries and restaurant breweries. Among the main ones include lower cost, simple operation, and the possibility of convenient collection of so-called “quilt”. It is layer of dead yeasts. Their presence in the beer leaves an unpleasant sour – bitter tinge.

But there is one advantage of the technology of open fermentation for small breweries, which is irrelevant for big breweries. And that is the opportunity to show the beer production in its different phases . Who ever visited a microbrewery 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. The operator of a brewery can boast before the guests with this attraction. The view of the modern brewery that is full of stainless steel closed tanks definitely cannot replace that interesting experience.
