Just found out from The Full Pint that Millstream Brewing will be brewing their first high proof beer (thanks to SF 2088) next week. According to the website, it will be a 8% Weizenbock (a dark wheat beer). They mentioned most will be kegged, but also left open the possibility that a limited quantity of 22 oz. bombers will be available. They anticipate it should be done sometime in June.
Also mentioned was that Millstream hopes to bring out 4 different high proof beers this year, and will allow customers to choose which one will go into regular production.
