The first R&D Series for 2016 will be released by New Glarus Brewing Co. in two weeks.

The New Glarus, Wis.-based brewery’s newest beer is Vintage 2015, a 5 percent ABV “American gauze” that is a blend of beers brewed in 2012 and 2014 and includes Wisconsin wheat and aged hallertau blanc hops. The beer was soured naturally in the brewery’s coolship before being oak barrels and was bottled in July 2015.
