We use only natural ingredients in our brewing process: hop, barley, yeast and water from our own spring. Fermentation is done with a type of yeast that is most active at 18°C to 20°C. We fill the bottles with the beer, yeast and sugar. Consequently, La Trappe continues to ferment in the bottle and develops a unique aroma. The flavour and aroma get all the time to ripen. The result is La Trappe, an authentic Trappist beer.
