What Does ‘GSM’ Mean?

GSM is an acronym used for Grenache, Shiraz, and Mataro red blends(*1). Shiraz can also be referred to as Syrah and Mataro as Mourvèdre (Monastrell)(*2). You may see other letter combinations such as ‘SGM’ and ‘MGS’. The first letter indicates the grape with the highest concentration in the blend. The grape used most in these blends is Grenache, followed by Shiraz and finished with Mataro(*1).

Where Did GSM Wine Blends Originate?

GSM originated in the Rhône valley in France at the base of the Rhône Alpes (French Alps) which border Switzerland and Italy(*1-3). The Southern Rhône region – notably Côtes du Rhône produces, on average, 380 million bottles of wine annually(*4).

Australian GSM – And What to Expect in Your Glass

GSM grapes have been cultivated in Australia for up to 150 years! The most common locations to find GSM are in the Barossa Valley and McLaren Vale(*1).

Typically, GSMs are:

  • Medium to full-bodied.
  • Full of sweet fruit flavours such as red berries, rich dark fruits, and spice.
  • Soft and smooth on the finish.

Why Make a Red Blend Rather Than Single Varietals?

By using a blend of wine grapes, producers have extensive control over the final flavour(*2).

A Classic Five-Star Blend Bursting with Flavour

Palate: Enthralling red fruits, savoury nuances. Fleshy in the mid-palate with a superb fresh finish.

Drink today or cellar – or why not do both as this is priced very well from $22 per bottle.

2019 Tim Smith Wines, ‘Barossa’ – Mataro, Grenache and Shiraz (MGS)
A Complex Old-Vine Vintage with a Twist

As Mataro makes up the bulk of this blend, it is more complex and exhibits more savoury flavours and spice than its counterparts(*1). Mataro also gives the wine an impressive ageing capacity. You can either open it today or cellar for enjoyment in the years to come(*10).

Aroma: Oak and aniseed.
Palate: Mataro gives good weight and complexity which sits gently on spices and juicy dark fruits(*1,11,12).

When you are ready to try a GSM with intriguing layers, this is the one! Priced from $23(*12).

2018 Torbreck, ‘The Steading’ – Grenache, Mataro and Shiraz (GMS)

For a more premium GSM, look no further than Torbreck’s old-vine, ‘The Steading’. This GMS is really juicy, vibrant, fresh, easy-drinking and a delight on the palate(*1,13,14).

Aroma: Gentle violet and spicy star anise unveil an orchard of fruits.
Palate: Pure fruit aromas continue onto the palate. Through the middle, tannins emerge to make this wine an absolute stand-out.

 You would expect to pay a mighty sum for a wine of this quality, but it is priced incredibly well, with half-bottles starting at $22.

All of Summer Hill Wine Shop’s staff have their favourites. For Alex, Torbreck’s ‘The Steading’ is one of his top GSM picks. If ‘slurpable’ was a word, it would certainly be synonymous with this GMS.
