“In the fall of 1991, the monks at Abbaye Notre-Dame de Scourmont in the south of Belgium contracted with monks at the Dutch abbey Koningshoeven to brew Chimay Blanche because construction at their own brewery limited production. To ensure the beer tasted no different from the Blanche brewed at Chimay, workers filled tanker trucks with water that would be shipped to Koningshoeven.”
