The story
The co-op first met in January 2006 with sixteen people in attendance. By 2010, the growing organization raised more than $325,000 and found a location to begin operations. Black Star brews two groups of beers, the "rational" and "irrational". Rational beers are types beer drinkers may be familiar with and made with mostly traditional ingredients. Irrational beers are experimental and innovative with flavors not everyone may find palatable.
