Style notes: Quadrupels or "Quads" are characterized by the immense presence of alcohol and balanced flavor, bitterness and aromas. Its color is deep amber to rich chestnut/garnet brown. Often characterized by a mousse-like dense, sometimes amber head will top off a properly poured and served quad. Complex fruity aroma and flavor emerge reminiscent of raisins, dates, figs, grapes, plums often accompanied with a hint of winy character. Caramel, dark sugar and malty sweet flavors and aromas can be intense, not cloying, while complementing fruitiness. Though well attenuated it usually has a full, creamy body. Hop characters do not dominate; low to low-medium bitterness is perceived. Perception of alcohol can be extreme. Clove-like phenolic flavor and aroma should not be evident. Chill haze is acceptable at low serving temperatures. Diacetyl and DMS should not be perceived. Well balanced with savoring/sipping drinkability. Oxidative character if evident in aged Quads should be mild and pleasant.
