A new release this weekend from Jester King Brewery will use the “waste” from one beer to make another one.

The beer in question is named Grim Harvest, a 5.8 percent ABV farmhouse ale that has been conditioned on “spent” blackberries sourced from Oregon that were used in the Austin-based brewery’s Nocturn Chrysalis. This is not the first time that Jester King has used this process, as Detritivore (5.5 percent ABV) is refermented with the same Michigan cherries used in the production of Montmorency vs. Balaton barrel-aged sour ale (6.7 percent ABV), and La Vie en Rose (6.2 percent ABV) is refermented with the “spent” raspberries that were used for Atrial Rubicite (5.8 percent ABV.)

Jester King Grim Harvest 750ml Bottle Label Feature

“Several years ago, we noticed that the refermented fruit from our beer still had a lot of character left in it,” reads a post on Jester King’s website. “So we decided to do a second refermentation of the fruit to draw out more of that character. The inspiration for this technique also came from reading that Cantillon had once done this. We have now completed this technique with blackberries for Grim Harvest.”

According to Jester King, Grim Harvest will be packaged in 750ml bottles ($18) with a total of 800 bottles available and a limit of one bottle per person. In addition, the brewery will be releasing 4,00 750ml bottles of the eighth batch of Funk Metal, an 8.2 percent ABV sour stout brewed with pale malt, black malt, chocolate malt, caramalt, brown malt, carafa malt, dark crystal malt and roasted barley as well as millennium and East Kent golding hops before being refermented in oak barrels.
