Beer Description

Keen Observation is a golden sour beer aged in unrinsed Map of the Sun barrels. We started off by fermenting a clean golden with Saccharomyces in a stainless steel fermentor for about 2 weeks, then moved that clean beer into unrinsed Map of the Sun barrels and let it age there for months. All of the acidity and Brett characteristics you’ll experience in Keen Observation are derived from the same microbes that fermented Map of the Sun.
