Red grapes produce an amazing array of red wine types: from the boldest, heartiest big reds, to elegant and structured dry red wines, to sweet and simple picnic sippers. So much depends on where grapes are from and what the winemaker does with them, but the most important factor is the variety of the grape itself.
There are the familiar international red varieties – Cabernet Sauvignon, Pinot Noir, Merlot and more – produced in the world’s top winemaking regions. Then there are regional red varieties, which produce types of red wine nearly synonymous with their place of origin, such as Sangiovese, from Italy, and Tempranillo, from Spain. There are hundreds more red grape varieties regularly used to make wine around the globe. (Source – Totalwine.com)
