Quadrupel

The Belgian-Style Quadrupel (Quad) is a dark, complex, and very strong ale. Originating from the Trappist monastic brewing tradition, the style name was commercialized by De Koningshoeven Brewery (La Trappe) in the Netherlands in 1991.

Notes: Quads represent the pinnacle of monastic brewing strength, building linearly upon the Single, Dubbel, and Tripel hierarchy.

Flavor Profiles

Malt Profile:

Caramel, dark sugar and malty sweet flavors and aromas can be intense, but not cloying, and should complement fruitiness.

Not present to very low

Fermentation Character:

Perception of alcohol can be strong. Complex fruity attributes reminiscent of any of raisins, dates, figs, grapes, or plums are often present and may be accompanied by wine-like attributes at low levels. Clove-like phenolic flavor and aroma may be present at low to medium-low levels. Noticeable ester profile. Fusel alcohols should remain in balance and not overwhelm overall aroma and flavor. Diacetyl and DMS should not be present.
