A Belgian quadrupel (or quad) is a type of Belgian Strong Ale with an impressive ABV and medieval European roots; seriously, Catholic monks were well-regarded brewers in the Middle Ages, perfecting the recipes for rich, malty beers. The quadrupel itself did not emerge until the 1990s, and like so many European fads before it (nods to the Spice Girls), met a real appreciation from U.S. markets. Quadrupels are complex and tasty ales, though the flavor can vary from caramel to dried fruit to spice depending on the yeast strains and roasted malts added as well as the beer’s age; you’ll likely notice an alcohol taste as a consequence of the high ABV, so you’ll want to sip and savor your quad like a fine wine.
