A new collaboration between The Bruery & Stone Brewing Co. brewed in Berlin is based on The Bruery’s Ride That Goat.

The new beer is named Fahrt Die Ziege, a 9 percent ABV imperial wheat ale and aged in barrels for four months before being blended a fresh non barrel-aged version of the ale conditioned on strawberries that were locally sourced in Germany. The new ale was brewed in Stones Berlin brewery and is based on The Bruery’s Ride That Goat, a 13.8 percent ABV weizenbock-style ale that debuted in 2015.

Fahrt Die Ziege is one of the brewery’s Groundbreaking Collaborations that is being brewed at Stone’s new Berlin facility, which opened in Sept. 2015 after more than a year of construction. In 2014, StoneBerlin launched an Indigo campaign online that eventually raised more than $2.5 million to build the new brewery, with contributors having the option of being awarded large-format bottles of 14 different collaboration beers that will be produced in the next year. However, smaller format bottles will be sold of some of the resulting collaborations.

According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Fahrt Die Ziege will be packaged in 750ml bottles, although larger format bottles will also be available for some beers to the Indigo contributors. An email sent to the brewery for additional information was not immediately returned.
