National IPA Day, also known as National India Pale Ale Day, is celebrated worldwide every first Thursday of August. This holiday was established in 2011 by craft beer expert Ashley Routson to honor one of the most popular styles of craft beer, the India Pale Ale (IPA). The day encourages beer enthusiasts to enjoy and explore various IPA brands, promoting a sense of community among breweries, pubs, and bars. Traditionally, participants may indulge in IPAs, host tasting parties, or attend beer festivals and events focused on this distinctive beer style. Originating in England in the early 19th century, IPAs evolved from heavily hopped ales designed for export to British colonies, particularly India. The craft beer revolution in the 20th century led to a resurgence in IPA popularity, particularly in the United States, where numerous styles have been developed.
