The next fruited variant of The Collective Brewing Project’s Petite Golden Sour will be released before the end of the month.

The newest incarnation of the ale will be Blackberry Petite Golden Sour, a 4.5 percent ABV sour golden ale brewed with brettanomyces bruxellensis var. dire,  lactobacillus delbrueuckii and brettanomyces lambicus before being aged in wine barrels with blackberry puree sourced from Oregon. According to co-owner Ryan Deyo, the beer was conditioned on 42 pounds of blackberry puree per barrel for three and a half months before being bottled.

This will be the fifth version of Petite Golden Sour to be sold so far, although there are multiple versions still scheduled to be released in the future:

Blackberry Petite Golden Sour will be packaged in 500ml bottles ($12) with approximately 1,400 bottles available when it goes on sale at the brewery on May 26 to member’s of The Collective Brewing Project’s Growler Club, with sales to the general public starting on May 28. However, unlike previous versions, there will be no sales on Friday and the new variant will have a purchase limit of 12 bottles per person.
