While Tannat originated in the Basque country of southwest France, it’s best known as the national grape of Uruguay, where it was first planted by the Basque immigrant Pascual Harraigue in the 1870s. The name of the grape refers to its high level of tannin, owing to its thick skins and many seeds. Tannat is well-suited to the coastal climate of Uruguay in part because of its thick skins, which make it resilient to both rain and drought. The grape is used to make a single varietal red wine that in modern times is usually unoaked to give it a fresher style, as well as rosé and sparkling wine. April 14 is Tannat Day 2024.
