Kolsch I

OYL-017

Available in Probrew pitches only

Yeast Thumb 17

An enthusiastically top cropping, lager-like ale strain from the Kolsch region, Kolsch I is lightly fruity, crisp and clean, and accentuates hop flavors well. Sulfur disappears with age. This strain can be fermented colder than Kolsch II (OYL- 044), and is powdery and slow to drop clear (filtering recommended). Kolsch II (OYL-044) is a little easier to manage.
