Whether it's hops, water, barley or malt - only the finest ingredients find their way into our beer. Only the strictest of quality controls - from the raw materials to the finished product - help guarantee the unique and unmistakable flavor of Erdinger's wheat beer specialties. Hops We use only hops supplied by a registered grower subject to independent monitoring. They are produced with the optimum use of fertilizer and lowest possible use of pesticide. The hops come exclusively from the Hallertau region, about 50 kilometers from the brewery. Malt Our malt comes exclusively from registered malthouses. Only pure-grade wheat and barley are processed. New types of barley and wheat are developed in collaboration with the malthouses, growers and seed producers and tested for their brewing suitability. Controls are implemented from the field (field inspection) to the point of delivery of the malt (incoming inspection). Water The water used for brewing and cleaning comes exclusively from two of our own deep springs, which are approximately 160 m deep. The water is of excellent drinking-water quality. Ongoing testing of the water is undertaken by internal and external institutions. Yeast The top-fermenting yeast used by Erdinger Weissbräu is unique the world over and is grown and stored in our own traditional pure-culture environment. The yeast is largely responsible for the typical taste of Erdinger Weissbier varieties.
