From the brewery:

Named after the year Peter Walker patented the Burton Union system, 1838 is brewed exclusively on this historic set at Thornbridge. This premium pale ale showcases the finest ingredients, blending Maris Otter malt with Savinjski Goldings hops to create a full-bodied beer with a light amber hue. Expect rich, biscuity malt flavours, balanced by floral hop notes and a crisp, refreshing finish.
