In 1928, the brewery introduced La Trappe Blond - a blond and under-fermented ale with 4% ABV - and later continued to release a variety of brews, including pilsners, bocks, and Dortmunders. In the 1960s, La Trappe looked to collaborate with another Belgian brewery - Stella Artois - due to the increasing demand. The collaboration was short-lived as the monks decided to take the brewing process back into their own hands in 1980.

Like the other Trappist breweries, La Trappe uses the Authentic Trappist Product (ATP) logo on their beers. In order to use this certification, the brewery must fulfil the following requirements:

1) The product(s) must be made within the walls of a Trappist abbey
2) The product(s) must be made by or under the supervision of the monastery community
3) Most of the profit must be spent on social work

As such, La Trappe doesn’t brew for profit, but instead uses every penny it earns to fund charitable programs and raise money for the monastery. The brewery prioritises corporate social responsibility and also sustainability. By working with the Diamant Group and the Prins Heerlijk foundation, La Trappe can offer work to people who are out of touch with the job market.
