Roeselare beer is a traditional Belgian beer style that originates from the city of Roeselare in West Flanders. Known for its unique sour flavors, it is often produced using a blend of different fermentation techniques, including wild yeast and bacteria. This results in a complex taste profile that can range from fruity to tart. The brewing process typically involves aging the beer in wooden barrels, which contributes to its distinctive character. Flanders red ale and oud bruin are popular examples of Roeselare beer, showcasing the region's rich brewing heritage and commitment to quality craftsmanship.
