Belgian-Style Quadrupel – Belgian Origin Ale Styles

Belgian-Style Quadrupel Style

  • Color: Amber to dark brown
  • Clarity: Chill haze is acceptable at low temperatures
  • Perceived Malt Aroma & Flavor: Caramel, dark sugar and malty sweet flavors and aromas can be intense, but not cloying, and should complement fruitiness.
  • Perceived Hop Aroma & Flavor: Not present to very low
  • Perceived Bitterness: Low to medium-low
  • Fermentation Characteristics: Perception of alcohol can be strong. Complex fruity flavors, such as raisins, dates, figs, grapes and/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. Diacetyl and DMS should not be present.
  • Body: Full with creamy mouthfeel
  • Additional notes: Head should be dense and mousse-like. Quadrupels are well attenuated and are characterized by an intense alcohol presence balanced by other flavors, aromas and bitterness. They are well balanced with savoring/sipping-type drinkability. Oxidized character, if present in aged Quads, should be mild and pleasant.
