To mark the milestone anniversary, New Glarus is releasing its 20th Anniversary Ale, modeled after the Belgian Dubbel style. 20th Anniversary Ale is just hitting store shelves this week. It’s intended to be a beer that gets better with age, a symbol that won’t be lost on the New Glarus faithful. "Deb wanted something that would improve with age, a beer people could buy, store and something that gets better as the years go by," says Dan.
