Quadrupel
type of beer, with an alcohol by volume of 9.1% to 14.2%
A Quadrupel (Flemish for 'quadruple') is a type of beer, with an alcohol by volume of 9.1% to 14.2%.
There is little agreement on the status of Quadrupel as a beer style. Writer Tim Webb notes that similar beers are called Grand Cru in Belgium even though the idea is derived from the Belgian beer naming convention that uses numerical values descriptive of the number of prominent ingredients.
Quadrupel is the brand name of a strong seasonal beer La Trappe Quadrupel brewed by De Koningshoeven Brewery in the Netherlands, one of the twelve Trappist breweries in the world.
In other countries, particularly the United States, quadrupel or quad has become a generic trademark. The term may refer to an especially strong style of dark ale with a spicy, ripe fruit flavor.

Why this record matters
The phrase “type of beer, with an alcohol by volume of 9.1% to 14.2%” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Nov 17, 2025. The linked authority identifier is Q7268438. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
