Pinot Grigio Day, also known as International Pinot Gris Day, is observed worldwide every May 17 to celebrate the popular white wine grape variety, pinot gris. This grape, which originated in Burgundy, France, is known for its grayish-blue fruit and can produce a range of wine styles, including fuller-bodied wines from regions like Alsace and lighter-bodied Italian pinot grigio. The day was established in 2017 by Cavit, an Italian winery, and has been celebrated on May 17 since 2018 after initially being known as National Pinot Grigio Day. Typical customs include sharing a bottle of pinot gris with friends, attending wine tastings, and enjoying food pairings with the wine, such as seafood and pasta dishes. Participants often use social media to promote the holiday with hashtags like #PinotGrigioDay and #InternationalPinotGrisDay.
