World War I Accelerates The Decline Of Traditional India Pale Ale

During World War I, British brewing was reshaped by wartime controls, higher taxation, and restrictions on raw materials. Brewers were forced to reduce the strength of their beers, and India Pale Ale was affected along with other British styles. The older tradition of stronger, well-attenuated export IPA became increasingly difficult to maintain under wartime conditions. The impact continued after the war. British beer strengths did not fully return to prewar levels, and IPA increasingly survived in Britain as a weaker bottled or draught beer rather than as the stronger export style associated with the nineteenth century. Examples from the interwar period show British IPAs with significantly lower gravities than their Victorian predecessors. World War I did not by itself end India Pale Ale, but it accelerated an existing decline. By weakening beer strengths and changing the economics of British brewing, the war helped push traditional IPA away from its nineteenth-century identity and toward the much lighter British IPAs that persisted through much of the twentieth century.
