During the Gold Rush, one of the most popular beer styles was the export stout. It was brewed at a higher gravity to survive the long overseas voyage from Dublin. Flying Cloud San Francisco Stout from Anchor Brewing is made with this history in mind, and is part of The Argonaut Collection, a series of adventurous beers from one of America's oldest breweries. The 7.4% stout arrives with a dark, chocolaty maltiness and a dry finish. It hits store shelves in March and is the first beer Anchor has released in 4-packs since 1971.
