This weekend, New Glarus Brewing Co. is releasing not one, but two different additions to its most popular series.

The first release will be Kriek, a 7.6 percent ABV spontaneously fermented ale brewed with three-year aged hops and local wheat before being aged in oak vats and conditioned on cherries sourced from Door county in Wisconsin. This is the second time that New Glarus has released a kriek-style ale in the R&D Series after Bourbon Barrel Kriek was released in 2010, although that beer was aged in bourbon barrels before being bottled.

In addition, New Glarus will be releasing Vintage 2017, a 5 percent ABV “American gueuze” that is a blend of beers brewed in three different years. The beer was soured naturally in the brewery’s coolship before being aged in oak barrels and is the fourth Vintage release so far:

The new beers will be the final two releases in the brewery’s R&D Series to be sold this year after 25th Anniversary Ale (11.5 percent ABV) was released on June 8.

According to a post on New Glarus’ Facebook page, both Kriek and Vintage 2017 will be packaged in 500ml bottles ($15) with a four bottle per person per day limit and will be available at New Glarus starting on Aug. 10.
