Donnington still produces its beers by much the same recipe that has always been used. Spring water (or in brewing terms ‘liquor’) is drawn from the spring beside the mill pond and used as the main ingredient along with barley, malt and hops. Until the mid 1960s, the barley was grown on the local estate but today it’s brought as malt from Norfolk. The hops are from Herefordshire and Worcestershire. The original mill is still used in the brewing process and the mill wheel drives some of the machinery used by the brewery.
