La Trappe Quadrupel Oak Aged (11%)

In 2009, the Koningshoeven Brewery reinstated an old tradition by aging La Trappe Quadrupel in oak barrels, thus creating a unique Trappist ale with a perfectly balanced flavour, special aroma of wood, and an alcohol content of 11%.

The complex taste depends on the type of barrel in which it is aged and therefore, each batch is different. The ale continues to ferment after bottling, may be kept for many years, and offers real indulgence to the genuine ale lover.


The aging process involves new as well as used barrels. The tantalising combination of flavours thereby created depends on the drink that had been previously stored in the barrels, whether it was port, whisky, wine, or brandy. The ultimate taste is also affected by the type of wood the barrel is made from. New oak casks, for example, give the ale its characteristic tannins, which impart a delicate vanilla and almond flavour.

Batch 33

Bourbon US


New Oak Medium Toast


New Oak High Toast


Batch 33 has a dark amber colour, darker than the regular Quadrupel. The head is beige in colour and consists of very fine bubbles.

The main component of this batch spent 2 years maturing in American Bourbon Whiskey barrels from Kentucky. Due to this long maturation process and secondary fermentation in the bottle, the ABV has increased to almost 12%.

There are pronounced notes of Bourbon Whiskey in the nose and palate, with hints of vanilla, oak, almond and prunes. Batch 33 is extremely flavourful and complex,

resulting in a pleasant, even balance between La Trappe Quadrupel, Bourbon Whiskey and oak. New associations keep cropping up during the tasting process. Despite the considerable sweetness, the carbonation of the beer keeps it fresh and produces a pleasant tingling sensation.

The taste of alcohol is clearly present in the finish. As the beer warms up, the taste of the oak becomes more pronounced, the beer becomes richer in tannins and a soft note of vanilla creeps in.

A highly recommended beer, characterised by great complexity and a harmonious taste.

A very high-quality tasting beer to be enjoyed in utter peace.
