Just one month after Wild Bitter was released, New Glarus Brewing Co. has another beer in its R&D series ready to go.

The New Glarus, Wis.-based brewery will be releasing R&D Vintage 2014, a 6 percent ABV “sour blonde” gueuze composed of a blend of one-, two- and three year-old beers aged on oak and bottled in August 2014. The release of the new beer is meant to coincide with the 26th Annual Village Polka Fest and Beer, Bacon, & Cheese Event, which takes place in the town of New Glarus every year.
