The brewers only use natural Burton spring water and traditional varieties of barley and hops (Maris Otter Barley, Fuggles and Goldings hops), rather than less expensive, commercially grown, modern hybrids. Unique in this world, it is still brewed in the oak casks of the Burton Union to preserve its unique character, consistent quality and taste. Many brewers have abandoned this traditional method of brewing over the years due to its extra cost and labour intensive maintenance, which requires a skilled cooper to constantly service the wooden casks. It has been the commitment and belief of each Marston's Head Brewer to preserve the extra effort that goes into each brew that makes Marston's Pedigree such an exceptional beer. When you want a truly exceptional premium ale, Don't compromise, choose Pedigree.
