Major
grape varieties are
Shiraz,
Pinot noir,
Cabernet Sauvignon,
Merlot,
Chardonnay, About
130 different grape varieties are used by commercial winemakers in Australia. Over recent years many winemakers have been rediscovering so-called "alternative varieties" other than those listed above. Many varieties from France, Italy and Spain, for example
Petit Verdot,
Pinot grigio,
Sangiovese,
Tempranillo,
Nebbiolo,
Malbec,
Barbera,
Arneis,
Fiano and
Viognier are becoming more common. Wines from many other varieties are being produced. Australian winemaking results have been impressive and it has established benchmarks for a number of varietals, such as Chardonnay, Pinot noir and Shiraz. Moreover, Australians have innovated in
canopy management and other viticultural and in wine-making techniques, and they have a general attitude toward their work that sets them apart from producers in Europe. Australian wine-makers travel the wine world as highly skilled seasonal workers, relocating to the northern hemisphere during the off-season at home. They are an 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 blends 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. A very similar blend is traditional to
Priorat (in
Catalonia, Spain), still based on Garnacha (Grenache), but adding Mazuelo (Carignan), Syrah, and Merlot (same GS, different M's). Grenache is the lightest of the three grapes, producing a pale red juice with soft berry scents and a bit of spiciness. As a blending component, it contributes alcohol, warmth and fruitiness without added
tannins. Shiraz can contribute full-bodied, fleshy flavours of black fruits and pepper. It adds colour, backbone and tannins and provides the sense of balance such blends require. Mourvèdre contributes elegance, structure and acidity to the blend, producing flavours of sweet plums, roasted game and hints of tobacco. ==Production==
