National Mourvèdre Day is observed worldwide every May 21 to celebrate the Mourvèdre grape variety, which is believed to have originated in Spain and is now widely cultivated in various countries, including the United States. The day was established following the 2017 Battle of the Texas Mourvèdre, where judges tasted and selected a winning wine from Texas wineries, leading to the decision to commemorate this event annually. Mourvèdre, also known as Mataro or Monastrell, is recognized for producing tannic wines with high alcohol content and is commonly used in varietal wines, rosés, and GSM blends (Grenache, Syrah, Mourvèdre). Typical customs include enjoying Mourvèdre wines paired with rich foods such as braised meats, stews, and aged cheeses, as well as vegetarian dishes like lentils and grilled vegetables. This celebration highlights the grape's significance in wine culture, particularly in regions like California, Texas, and Australia.
