Jester King Brewery has long been a proponent of using unusual ingredients in its creations, and a new beer released this weekend shows off a process it has only used once before.

Vague Recollection — 2017 Syrah & Sangiovese is a 6 percent ABV farmhouse ale refermented on pomace from sangiovese and syrah grapes, which is essentially the skins, pulp, seeds, and stems that are left after running wine grapes through a crusher. This process is is different than other releases from the Austin-based brewery that have conditioned beers on the “spent” whole fruit—i.e. La Vie en Rose and Detritivore.

Jester King has used the process once before, when it released 2016 Vague Recollection, a 6.1 percent ABV farmhouse ale refermented on pomace that was left over after brewing 2016 Bière de Lenoir.

“One of the things we like about this technique is the subtlety of the resulting flavors and aromas,” says a post on Jester King’s Facebook page. “Whereas beers like Cerveza de Tempranillo and Bière de Blanc du Bois are more hybrids of beer making and wine making, Vague Recollection is firmly in the beer camp. Aging on the pomace creates a really nice texture and delicateness to a very well attenuated base beer.”

According to Jester King, Vague Recollection — 2017 Syrah & Sangiovese is available at the brewery now packaged in 750ml bottles ($18) and has no purchase limit with approximately 6,500 bottles available.
