LalBrew® Köln™ Kölsch Style Ale Yeast

$158.00

LalBrew Köln™ is ideal for brewing traditional Kölsch-style beers and other neutral ales. The neutral character of this strain accentuates delicate hop aromas while imparting subtle fruity esters.

Through expression of a beta-glucosidase enzyme, LalBrew Köln™ can promote hop biotransformation and accentuate hop flavor and aroma. Colder fermentations will be more neutral in character, while warmer fermentations will have more fruit-forward ester profile.

Brewing Properties

In Lallemand’s Standard Conditions Wort at 68°F (20°C) LalBrew Köln™ yeast exhibits:

  • Fermentation that can be completed in 7 days, a bit slower than most ale strains. This is perfectly characteristic of this strain.
  • Medium to high attenuation and medium flocculation.
  • Neutral to slightly fruity and estery flavor and aroma.
  • The optimal temperature range for LalBrew Köln™ yeast when producing traditional styles is 59°F (15°C) to 72°F (22°C).

Lag phase, total fermentation time, attenuation, and flavor are dependent on pitch rate, yeast handling, fermentation temperature and nutritional quality of the wort.

Why Dry Yeast?

Yeast regularly contains under 7% water while dry brewing. Rigid standards of quality are upheld during processing to refrain from microbial pollution. The exceptional strength of dry yeast takes into account rigorous QC testing to guarantee that under 1 wild yeast cell or bacterium per million cells of yeast is detected while brewing.

When it comes to most strains, 1g of dry yeast includes at least 5 billion suitable cells; however, the figure will shift marginally depending on the batch. Please contact us with any questions.
