This is the world's strongest commercially available beer, brewed using six different yeast strains over seven months and then aged for half a year. Dark, rich, roasty, and complex, this well-made brew has a minimal head and hints of plum, grapes and tobacco, along with a noticeable but not overwhelming alcohol presence, in both taste and aroma. Worldwide Stout has much in common with a fine Port. Limited availability and it sells out fast.
