Grenache or Garnacha is one of the most widely planted red wine grape varieties in the world. It ripens late, so it needs hot, dry conditions such as those found in Spain, where the grape is believed to have originated. It is also grown on the Italian island of Sardinia, in the Colli Berici hills in the Vicenza province of Veneto in Northern Italy where it is known as Tocai Rosso, the south of France, Australia, and California's Monterey AVA, Paso Robles, Santa Barbara County, San Joaquin Valley and Willcox, Arizona.
