Three times a year, Sierra Nevada releases a limited-edition series of beers that push the extremes of brewing. Please note that the High Altitude beer you get may be different than the one pictured here, but it will certainly be delicious. Winter 2023: Bigfoot Barleywine-Style Ale Beer Description: Bigfoot is a beast of a beer, packed with bittersweet malt and heaps of aggressive whole-cone Pacific Northwest hops. First introduced in the winter of 1983, Bigfoot is a cult-classic brewed in the barleywine style—strong and robust with the refined intensity of a wine. Bigfoot is prized by beer collectors for aging in cellars. Under the proper conditions, it can develop enticing new flavors and character as it matures in the bottle. Each new release or “expedition” is vintage dated. Collect your own and savor the evolving flavors. 9.6% ABV and 90 IBU Spring/Summer 2023: Hoptimum Triple IPA Beer Description: Each year, we try to top ourselves by making the hoppiest, most intense IPA we can muster. We sample endless hop varieties during the annual harvest to choose the ultimate mix—flavorful and aggressive, yet refined. Then we push them beyond their limits to reimagine Hoptimum, a remarkably drinkable triple IPA. 11% ABV and 75 IBU Fall 2023: Narwhal Imperial Stout Beer Description: Narwhal Imperial Stout is inspired by the mysterious creature that thrives in the deepest fathoms of the frigid Arctic Ocean. Rich with notes of espresso, baker’s cocoa, roasted grain and a light hint of smoke, Narwhal brims with malt complexity. Aggressive but refined with a velvety smooth body and decadent finish, Narwhal will age in the bottle for years to come. 10.2% ABV and 60 IBU
