The Boundary Bay Brewing Company, also known as the Boundary Bay Brewery & Bistro is a microbrewery and brewpub in Bellingham, Washington. It was founded in 1995 by Ed Bennett, and has won numerous awards in national and international beer competitions. It is named after Boundary Bay, a bay north of Bellingham that is partially Canadian and partially American territory. During prohibition, rum-runners and bootleggers crossed illegal alcohol into the States through this unique geological feature.
The New Brewer, a publication of the Brewers Association, announced in their 2008 annual industry review that the Boundary Bay Brewery & Bistro was the nation's largest brewpub based on number of barrels sold (a brewpub being defined as a restaurant-brewery that sells 25% or more of its beer on site).
