As it has for the past six years, Russian River Brewing Co. has released its Framboise For A Cure, but this year’s release has a twist.

According to a post on the Santa Rosa, Calif.-based brewery’s Facebook page, this year’s incarnation is a draft-only release due to “production schedule issues.” The 6 percent ABV sour barrel-aged blonde ale is a blend of the brewery’s Temptation and Sonambic that has been aged in chardonnay wine barrels and conditioned on two pounds per gallon of organic California-grown raspberries. The beer was first released in 2010 and has been historically packaged in 375ml bottles, with all proceeds donated to the Sutter Pacific Medical Foundation of Santa Rosa.

While there will be no bottles of this year’s Framboise For A Cure, the sour ale is being sold in 64-ounce growlers ($60) with refills priced at $51 and a limit of one growler per person. According to Russian River, the brewery filled 64 kegs of the beer, meaning it should be available on tap “for several weeks.”
