Boundary Bay Brewery is one of the Pacific Northwest's original craft breweries, independently owned and operated in Bellingham, Washington since 1995. Known for handcrafting ales and lagers using a 17-barrel brew system, this brewery has built a devoted regional following for its commitment to quality and community. This Costco exclusive offering features a seasonal selection from Boundary Bay's rotating lineup, packaged in 6-packs of 12oz cans.

Boundary Bay's seasonal beers showcase the brewery's range and creativity, drawing on Washington-grown ingredients and Pacific Northwest brewing traditions. Their seasonal offerings have included well-regarded beers such as Cabin Fever, a rich and malty Winter Warmer brewed with 2-Row Pale, Munich, Crystal, Carastan, Chocolate malts, and Oats, hopped with Zeus, Simcoe, Willamette, and Celeia for a balanced character and extended conditioning period that delivers a smooth, deceptively strong finish. Other seasonal releases rotate throughout the year, reflecting the brewery's deep roots in Bellingham and the surrounding Whatcom County region.

Boundary Bay distributes throughout Whatcom, Skagit, Snohomish, and King Counties, and has been a fixture of Washington's craft beer scene for three decades. Their beers are contract-brewed in partnership with Black Raven Brewing following the closure of their Railroad Avenue location, ensuring continuity of their beloved recipes.
