Durif Day is observed worldwide every June 10, celebrating the Durif grape variety, also known as Petite Sirah, which is recognized as the “best unknown wine in Australia.” This day was established by the Riverina Winemakers Association in New South Wales, a region that produces a significant portion of Australia's grapes and wine. The Durif grape was created in the 1860s by French botanist François Durif and has since become popular in Australia and California, where most Durif wines are labeled as Petit Sirah. Celebrations typically involve enjoying a bottle of Durif wine, visiting vineyards, and participating in wine tastings. The wine is known for its dark, intense flavors and pairs well with rich foods, making it a fitting choice for the occasion. Participants are encouraged to share their experiences on social media using the hashtag #DurifDay.
