Tannat got a claim to a fame in the early 2000s thanks to its high anthocyanin levels thanks to its high tannin content (from the red grape skins) as it was said to have a high level of resveratrol (an anti-cancer compound). Long before that bit of press came about, Tannat is home in Madiran in the southwest of France and more recently it is found a home in Uruguay. In both of these countries it is often blended with Cabernet Sauvigon or Merlot to help soften its high tannins.
