Our company only purchases and processes quality hops that meet our strict quality requirements. Our hops are professionally hand-selected and hundreds of our freshly harvested hops are sampled for strict scrutiny. The special combination of bitter and aroma hops from the best quality growing regions is unique and is a key component of the high demands of Warsteiner.

Malt from selected and audited two-row spring barley of specified types and provenances.

Another top-quality attribute is the original and especially soft brewing water. This is obtained from the Kaiserquelle, among other sources.
Albert Cramer Senior discovered the Kaiserquelle (‘Kaiser’s Spring’) at the edge of the Arnsberg Forest, close to the Waldpark brewery of today. With a water hardness of only one to two degrees, the water is especially suitable for brewing beer and contributes to the beer’s wholesomeness. The Kaiserquelle’s soft water, which still to this day feeds the Warsteiner Brewery’s water tanks, was crucial for the huge success of Warsteiner Pilsener, which was brewed from 1927 following the registration of water rights.
