International Happy Gose Day is observed worldwide every November 17, celebrating the unique style of German beer known as gose, which originated in the town of Goslar. This sour beer, characterized by its tart, salty, and herbal flavors, was first brewed in the early 13th century and gained popularity in Leipzig by the 18th century. Although the production of gose declined in the 20th century, it experienced a revival in the late 1980s and has since grown in popularity. To celebrate, enthusiasts are encouraged to enjoy a glass or two of gose, often brewed with malted wheat, coriander, and salt, and to share their experiences on social media using the hashtags #InternationalHappyGoseDay and #HappyGoseDay. The holiday was first celebrated in 2016 and has become a cherished occasion for gose lovers around the globe.
