In two weeks, New Glarus Brewing Co. will be releasing the final R&D beer of the year.

Pommier Sauvage is a 5.2 percent ABV fruited sour-style beer that has been “spontaneously fermented with varietal apples from Wisconsin’s Kickapoo Valley.” A label posted on New Glarus, Wis.-based brewery’s Instagram page indicates that the beer was brewed in Nov. 2015 and bottled in May of this year.

Pommier Sauvage is the final of three different beers in the brewery’s R&D Series to be sold this year: the first beer in this year’s series was Vintage 2015 (5 percent ABV) that was released on June 10 followed by Champ du Blanc (10 percent ABV) that was released on Aug. 12.

According to a post on New Glarus’ Instagram page, R&D Pommier Sauvage will be packaged in 500ml bottles ($10) and will be available at the brewery starting on Sept. 23, with a two bottle per person per day limit.
