The following ratio was used for Batch 33:
Bourbon US. 80%
New Oak Medium Toast. 15%
New Oak High Toast 5%

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.
