Australian wine important resource in the globalisation of wine and wine critic Matt Kramer notes that "the most powerful influence in wine today" comes from Australia. "GSM" is a name commonly used for a red wine consisting of a blend of Grenache, Shiraz (Syrah), and Mourvèdre. Blends where Shiraz is the main component are sometimes referred to instead as SGM. This blend originated from those used in some Southern Rhône wines, including Châteauneuf-du-Pape, though it is also found in South Australia, California (particularly Paso Robles, originating with Tablas Creek Vineyard), and Washington (Columbia Valley); smaller production exists in Argentina and South Africa.
Syrah Côtes du Rhône, where Grenache usually makes up the bulk of the blend. Although its best incarnations will age for decades, less-extracted styles may be enjoyed young for their lively red and blueberry characters and smooth tannin structure. Syrah has been widely used as a blending grape in the red wines of many countries due to its fleshy fruit mid-palate, balancing the weaknesses of other varieties and resulting in a "complete" wine. From the 1970s and even more from the 1990s, Syrah has enjoyed increased popularity, and plantings of the variety have expanded significantly in both old and new locations.
