Grenache – Syrah – Mourvedre blended wines – commonly known by the acronym GSM – are the particular specialty of the southern Rhone Valley in France. Grenache and Syrah are key in this part of the world, and are complemented in this instance by the addition of Mourvedre: an important but slightly less famous inclusion to the blend. GSM wines, which have been readily adopted by the New World, are rich, full bodied and leathery, and are characterized by flavors of dark fruit and spice. All three varieties have the Mediterranean coast as their homeland, and all three are very important to the region's viticultural makeup. Grenache, which contributes spice, red fruit and alcohol to the blend, is widespread in southern France and also in Spain, where it is known as Garnacha and is part of the Rioja blend. Mourvedre, the key grape variety in Bandol, shares this Mediterranean dispersal and is also found in Spain where it is known as Monastrell. It gives tannins, color and length to the wine. Syrah, with its structure and dark fruit, is very much a French variety and is the mainstay of the northern Rhone Valley. Nowadays it is also planted across the world from Australia to India.
