International Carignan Day is celebrated worldwide every last Thursday of October to honor the Carignan grape variety, which originated in Spain and is predominantly found in French wines. This grape, also known as Cariñena and Mazuelo, is characterized by its late budding and ripening, and it is primarily cultivated in regions such as Languedoc-Roussillon in France, as well as Italy and Spain. The day was established by Carignan Renaissance, a French association of wine professionals, to promote the visibility of this historic grape. Celebrations typically involve enjoying a glass or two of Carignan wine, gifting bottles to introduce others to the wine, attending wine tastings or vineyard tours, and sharing the occasion on social media using the hashtags #InternationalCarignanDay and #CarignanDay. Carignan wines are known for their high acidity and tannins, making them excellent companions for flavorful meat dishes and rich cheeses.
