Another fruited variant of The Collective Brewing Project’s Petite Golden Sour lineup is being released at the brewery today.

The newest incarnation of the ale will be Plum 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 plum puree sourced from Oregon. According to co-founder Mike Goldfuss, the beer was conditioned on on the puree for more than a month before being packaged.

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

  • Petite Golden Sour (4.5 percent ABV) — Draft and 500ml bottles
  • Apricot Petite Golden Sour (4.7 percent ABV) — Draft only
  • Blueberry Petite Golden Sour (4.7 percent ABV) — Draft only
  • Raspberry Petite Golden Sour (4.7 percent ABV) — 500ml bottles only
  • Peach, Vanilla And Cinnamon Petite Golden Sour (4.5 percent ABV) — Draft only
  • Blackberry Petite Golden Sour (4.5 percent ABV) — Draft and 500ml bottles
  • Plum Petite Golden Sour (4.5 percent ABV) — Draft only

Plum Petite Golden Sour will be packaged exclusively on-draft and will be priced at approximately $20 for a 32-ounce crowler with no purchase limit, and members of The Collective Brewing Project’s Growler Club will be able to use their allotments to purchase crowlers of the beer. In addition, Cranberry Petite Golden Sour is scheduled to be released on-draft at the brewery before the end of next week.
