We produce pressure and non-pressure stainless steel tanks for the brewing, food, pharmaceutical and chemical industries. Our main production activities are the design and manufacture of technological units of the brewery. We produce stainless steel beer tanks, CIP stations, bright beer tanks, breweries and beer production technologies.

Modern beer production using yeast was described in 1876, Louis Pasteur in his work A Study of beer. Yeasts are unicellular fungal organisms and are widely used in the food industry, especially in the production

of beer, wine and other alcoholic beverages, the production of which uses the main capability of yeast: Fermentation.

Fermentation is a process of conversion of organic matter (mostly sugars) in which the participation of microorganisms and their enzymes produce poorer energy substances. Fermentation of microorganisms obtains energy like breathing, while fermentation is simpler but also less efficient than breathing.

Spontaneous fermentation in beer production: Spontaneous fermentation means that the wort is allowed to ferment with naturally occurring yeasts. Fermentation takes place at higher temperatures, i.e. a top spontaneous fermentation. Previously, all fermented beverages were produced this way. Special yeast strains for different types of beers are a later product. The tradition of using wild yeasts in beer production survives especially in a few Belgian breweries using ancient recipes.

Top fermentation in beer production: Top fermentation is based on how yeast behaves at the final stage of the main fermentation. The top yeast produces a "crust" on the surface. Top-fermented beers are produced at temperatures of about 15-20 ° C using yeast Saccharomyces cerevisiae subsp. cerevisiae or by spontaneous fermentation. It is used to produce all top fermented wheat beers. The resulting yeast is collected from the vat level and the fermented wort is subsequently stored in barrels or tanks where it matures at natural or cellar temperatures for several days to months.

Bottom fermentation in beer production: Bottom fermented beers are produced by fermentation, which takes place at lower temperatures ranging from 8 to 14 ° C. Yeast from strain Saccharomyces cerevisiae subsp. uvarum. Subsequently, the beer lies for a month or more at temperatures close to zero. Bottom-fermented beers include most of the world's production, including most Czech production.

The primary difference between lower and upper yeasts (except sensory perception) is in their ability to process carbohydrates composed of galactose, fructose, and glucose - to process all the sugars that occur, thereby achieving better fermentation. Outer yeasts do not have this ability, and as a result, top-fermented beer is usually sweeter with lower levels of alcohol available. Top-fermented beers are the bearers of varied exotic fragrances and flavors, even without the addition of other ingredients, thanks to the higher fermentation temperature. Bottom fermented beer has a higher alcohol content, a clearer color and a more straightforward, typical taste. Cheers!
