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

The Chico, Calif.-based brewery will be releasing Raspberry Bigfoot, a 11.9 percent ABV barleywine that has been aged for approximately 12 months in wine barrels and conditioned on 90 pounds of fresh whole raspberries per barrel for about three months. 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 Red Wine Barrel Bigfoot (9.6 percent ABV) aged in red wine barrels; Scotch Style Ale (9.1 percent ABV), which was aged in bourbon barrels and Ovila Quad (10.3 percent ABV) aged in madeira barrels (11.5 percent ABV.)

In an email, Bill Manley, beer ambassador at Sierra Nevada, told Tenemu that Raspberry Bigfoot will be packaged in 750ml corked and caged bottles, with approximately 400 bottles available when it goes one sale exclusively at the brewery’s three on-site retail sites in “late November (or) early-December.”
