The signature grape of Uruguay is malbec, due to the country's close proximity to Argentina, where malbec is also the star.
Answer: False.
The signature grape of Uruguay is not malbec (as it is in Argentina), but tannat. Tannat is a tannic grape that originated in southwest France, although today more tannat is grown in Uruguay than in the entire rest of the world. Aged in oak to soften it, tannat (whose name refers to the dark color of the grapes) can be rich and mouthfilling, with black cherry, chocolate, and espresso flavors. In Uruguay, it is considered the perfect accompaniment to the popular local asados, wood-fired barbeques devoted to Uruguay's high-quality beef.
