International Cava Day is celebrated worldwide on April 23 and July 12 each year, recognizing the unique Spanish sparkling wine known as cava. The first date commemorates the 1969 adoption of official regulations for sparkling wines by the Ministry of Agriculture of Spain, while the origins of the July date are less clear but have been promoted by the Regulatory Board of the D.O. Cava. Cava, primarily produced in the Penedès region of Catalonia, was invented in 1872 by Josep Raventós, who sought to create a Spanish sparkling wine using local grapes after a phylloxera epidemic. The traditional grape varieties for cava include Macabeo, Parellada, and Xarel·lo, distinguishing it from Champagne, which uses different grape types. Celebrations often involve sharing a bottle of cava, attending tastings, or planning trips to wineries in Spain to learn about the production process. Participants are encouraged to share their experiences on social media using the hashtags #InternationalCavaDay and #CavaDay.
