Brewers’ yeast extractsMore than just a nitrogen source

Leiber-Fermentation S

Pure and well-balanced brewers’ yeast extract
Leiber-Fermentation S is partly debittered and contains a perfectly adjusted concentration of hop oils. Due to a very gentle treatment during the extraction process, the characteristics of the brewers’ yeast are very well preserved. This unique property of brewers’ yeast extracts allows the selective growth of certain microorganisms. In cooperation with numerous partners from universities and research institutions, we have been able to highlight the advantages of using yeast extracts in beer production. The increase of aroma-active components or the shortening of the storage time of the beer by faster by-product reduction are only a few examples describing the peculiarity and advantages of the yeast extract.
