America's Bitterest Brews Slideshow
120 Minute IPA, Dogfish Head Craft Brewed Ales
To create this extreme elixir, the Delaware brewery (founder Sam Calagione is the star of the Discovery Channels "Brew Masters") uses heaps of hops during the brewing process, then ages it for several more months with even more hops. The result: 120 IBUs and a head-spinning 18 percent ABV.
Mean Manalishi Double IPA, Hoppin' Frog Brewery
The deeply copper creation is jam-packed with gobs of hops, which impart plenty of pine and grapefruit aromas and flavors. Caramel keeps this hugely bitter hop bomb 168 IBUs (!) grounded.
