La Trappe Quadrupel
The beer that put the word "quadrupel" into the vocabulary, which is why the term describes a strength rather than a tradition.
- Strength
- 10% ABV
Also called Quadrupel, La Trappe Quad.
Dubbel and tripel are old abbey terms. Quadrupel is not: this brewery introduced it in 1991 for a beer stronger than its tripel, and the word spread from there into general use, particularly in the United States, where it is now applied to Belgian dark strong ales generally.
That history is the reason to carry the record. A reader who meets "quad" on a label is meeting a marketing term that became a category, and the beers it is applied to belong to a style that already had a name. This is the original, and it is malt-led, dark and warming in the way the older abbey strong ales are.
What it tastes like
Inherited from Belgian dark strong ale, because this beer sits within the normal range for it. BeerHQ’s comparative scale, not a measurement.
Why BeerHQ carries this beer

BeerHQ records no recipe, hop bill, malt bill, yeast strain, IBU or calorie figure for any commercial beer unless it is sourced. Nothing on this page is inferred from what the beer tastes like.
What is distinctive about it
- Introduced the term "quadrupel" in 1991, which subsequently became a general category name
- Brewed within a Trappist abbey in the Netherlands rather than in Belgium
If you like La Trappe Quadrupel
Worked out from what this beer actually tastes like rather than from what its style typically does. Three kinds of move, because “what should I try next” is three different questions.

Likely fits rather than promises. Taste varies, and a recommendation engine that claims certainty is claiming something it cannot know.
What to eat with it
Inherited from Belgian dark strong ale. BeerHQ does not duplicate pairings onto individual products unless the product genuinely differs from its style.
- Blue cheese
Dark fruit sweetness against salt and pungency, with high carbonation scrubbing the fat. A lighter-bodied alternative to a barley wine that achieves much the same balance.
- Mince pies
Dark candi sugar and Belgian yeast spice run parallel to the cinnamon, clove and dried fruit in the pastry.
- Christmas dinner
Enough residual sweetness to stand up to the dish rather than being flattened by it.
- Burrito
Malt sweetness rounds off the salt rather than compounding it.
Keeping it
Belgian dark strong ale is typically at its best 12–96 months after packaging, and time is working for it rather than against it.
Rewards age. Given cool, dark, upright storage this develops depth most drinkers would call an improvement. Buy two and compare.
