The Collective Brewing Project has bottled its first beer that incorporates fruit, but fans will have to wait another month to buy it.

According to owner Ryan Deyo, the Fort Worth, Texas-based brewery will be releasing Raspberry Petite Golden Sour, a 4.6 percent ABV sour ale brewed with brettanomyces bruxellensis var. drie. and conditioned on 42 pounds of raspberry purée. The new beer uses The Collective Brewing’s Petite Golden Sour (4.5 percent ABV) as its base before adding the raspberries and aging the final concoction for three months in French oak barrels.

This is the third incarnation of Petite Golden Sour to incorporate fruit, following Blueberry Petite Golden Sour (4.5 percent ABV) and Apricot Petite Golden Sour (4.7 percent ABV), both of which were draft-only releases in 2015. The new beer was bottled on March 18.

Raspberry Petite Golden Sour will be packaged in 500ml bottles ($15) with 964 bottles available and no purchase limits when it goes on sale at the brewery on April 28 to member’s of The Collective Brewing Project’s Growler Club, with sales to the general public starting on April 29. In addition, unlike previous versions, the new beer will not be available on draft due to a mishap at the brewery.
