assistant
Merlot is a red wine grape, and Cabernet Sauvignon is a red wine grape. They are both grown in the Bordeaux region of France, but the climate, soil, and other factors are different for each of these grapes. The result is that they produce different types of wine. Merlot is lighter and fruitier, while Cabernet Sauvignon is darker and more tannic.
