 The brewery is well known for its "huge taste" beers.
 Most of their brews are high in alcohol, with QUAD clocking in at 11.8% alcohol by volume, and a one-off 10th anniversary ale called Decadence brewed to 13% alcohol by volume.
 Hops Infusion is one of the bitterest examples of the IPA style.
 Weyerbacher is also a pioneer of aging beer in wooden barrels previously used for aging bourbon.
 This process was used to transform Old Heathen imperial stout into Heresy, Blithering Idiot barley wine into Insanity, Merry Monks Belgian tripel into Prophecy, and QUAD Belgian quadrupel into Blasphemy.
 These four styles are all very high-alcohol brews with complex flavor profiles; the barrel-aging lends additional oak and whiskey flavors.
