At Homebrew In Paradise http://www.homebrewinparadise.com/Index.aspx I can buy any grain in the store in the exact amount I want. Be it 1 oz or 30 lbs. I measure out myself what I need and pay the man. No extra grain laying around the house.
BTW..When is the tasting of the Irish Red against Kevin's? I'd like to see how the controlled fermentation worked out. Aloha!
