The Koningshoeven Brewery is one of the few Trappist breweries in the world authorized to use the "Authentic Trappist Product" logo. An ale can only be called Trappist ale when it is brewed within the walls of a Trappist monastery, under the supervision of the monastery's monks, and when part of the proceeds are destined for charity.

Only natural ingredients are used in the brewing process: hops, barley, yeast, and water from its own source. Fermentation is done with a type of yeast that is most active at 18 °C to 20 °C.

The bottles are filled with beer, yeast, and sugar. Consequently, La Trappe continues to ferment in the bottle and develops a unique aroma. The taste and aroma continuously mature. The result is La Trappe, an authentic Trappist beer.
