GSM (Grenache, Syrah, Mourvèdre)

GSM refers to a popular blend of three red grape varieties—Grenache, Syrah, and Mourvèdre—commonly used in Southern France’s Rhône Valley. Each contributes unique characteristics: Grenache adds fruitiness and softness; Syrah provides boldness, spice, and depth; Mourvèdre offers structure, tannins, and complexity. When combined, these grapes create balanced wines with rich fruit flavors, complexity, and a harmonious tannic profile. GSM blends are appreciated for their versatility, aging potential, and expressive regional style, making them a favorite among wine enthusiasts worldwide.
