Next month, Sierra Nevada Brewing Co. is adding a variant of one of its most popular beers to its Trip In The Woods Series.

The Chico, Calif.-based brewery will be releasing Red Wine Barrel Bigfoot, a 9.6 percent ABV barleywine that has been aged for approximately nine months in red wine barrels sourced from California’s Napa Valley. The new release uses Sierra Nevada’s Bigfoot barleywine (9.6 percent ABV) as its base, a beer that debuted in 1987.

The Trip In The Woods Series is made up of beers aged in various types of barrels and has included releases such as Barrel-Aged Lime Ale (9.3 percent ABV); Scotch Style Ale (9.1 percent ABV), which was aged in bourbon barrels; Ovila Quad (10.3 percent ABV) aged in madeira barrels (11.5 percent ABV) and Barrel-Aged Porter, a 7.4 percent ABV porter that was aged in red wine barrels.

In an email, Bill Manley, beer ambassador at Sierra Nevada, told Tenemu that Red Wine Barrel Bigfoot will be packaged in 750ml bottles, with about 2,000 bottles available when it goes one sale at the brewery’s three on-site retail sites in August. In addition, a limited number of bottles will be sent to distribution, mostly in the state of California.
