More than a year after the first batch of Colour Five was released, Jester King Brewery has started the process to produce more.

According to a post on the Austin, Texas-based brewery’s Facebook page, blueberries sourced from Brownsboro, Texas were run through a “crusher/destemmer” before being added to “mature, barrel-aged beer for refermentation.” The original incarnation of Colour Five (7.1 percent ABV) was released on Oct. 31, 2014 and was composed of a blend of 89 percent Das Überkind, a saison, and 11 percent RU55, a farmhouse red ale, as the base beer.

Jester King had attempted to produce a sour, barrel-aged beer with blueberries in 2013, but the entire batch was dumped down the drain after it was found to be too acetic for the brewery’s standards.

According to Jester King, the blueberries for the beer were added to the base beer to start the refermentation process on Thursday. An email to the brewery for additional information was not immediately returned.
