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.

- 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 12 – 20°C (54 – 68°F)

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