International Viognier Day is celebrated worldwide every last Friday of April, with the next observance on April 24, 2026. This day was initiated by Yalumba, an influential Australian winery known for its Viognier production, to encourage people to try Viognier wines, which are characterized by floral and fruity aromas reminiscent of Muscat and Riesling. Viognier, a white wine grape variety that nearly became extinct in the 1960s, is primarily grown in regions such as the Rhône valley in France, North America, South America, Australia, and New Zealand. Participants celebrate by purchasing and enjoying Viognier wines, attending wine tastings, or sharing their experiences on social media using the hashtags #InternationalViognierDay and #ViognierDay. The celebration is supported by various wineries, including Clonakilla, Guigal, and Domaine Jean-Louis Chave, among others. Viognier wines are known for their bold aromas and pair well with a variety of dishes, making them a versatile choice for food pairing.
