COLOGNE - GERMAN ALE STRAIN Cologne is a clean, crisp, traditional German Kölsch strain. A very low ester profile makes this strain perfect for Kölsch, and other light coloured delicate beers. Cologne has better flocculation characteristics than most Kölsch strains which allows brewers to produce clean, bright beers in a shorter amount of time.

Enhanced esters, higher flocculation, more concentrated yeast pack and higher viability after fermentation are just some of the many advantages liquid yeast has over traditional dry yeast products. Liquid yeast also allows for up to 10x more brews per batch – which means our yeast goes much, much further and is easier on your hip-pocket.
