Jopen Bier is a brewery rooted in the rich brewing history of Haarlem, the Netherlands. From the 14th century onwards, Haarlem was known as a thriving brewing city, and Jopen was founded in 1994 to revive that proud heritage. The brewery takes its name from the 'joop', a traditional large barrel once used in Haarlem's historic brewing trade, and has since grown from a regional craft brewer into one of the most recognised specialty beer brands in the Netherlands. Jopen's portfolio is broad and distinctive, built around high-quality specialty beers that blend historical recipes with modern craft brewing techniques. The brewery is known for styles ranging from traditional ales to more adventurous and innovative brews, always with a focus on authenticity and character. Their Koyt, a recreation of a medieval Haarlem grain ale brewed with a blend of oats, wheat and barley, is one of their most iconic beers and a direct reference to the city's brewing past. Over the years, Jopen has built a strong reputation in the Dutch craft beer scene. The brewery operates out of Haarlem and has earned recognition at competitions including the Dutch Beer Challenge. With a taproom experience rooted in the city's brewing legacy and a growing portfolio of collaborations, Jopen continues to put Haarlem firmly back on the map as a city of great beer.
