GSM wine is a blended red wine made from the Rhône Valley wine region grape varieties Grenache, Shiraz and Mourvèdre of France. The abbreviation has been adopted from the New World wine countries, especially Australia. The most famous expressions of the GSM wine is coming from the appellation Chateauneuf-du-Pape of the Rhône Valley, where the most used grapes are the magnificent trio. Although, the GSM blend has found a natural home in South Australia, more particularly in the Barossa Valley where these wines thrive in the local conditions. The warm climate, the topography and the reddish clay soils of the Barossa are perfect for the three varietals to achieve maximum ripeness and depth of flavour like nowhere else on earth. The profile and the characteristics of the GSM wines are usually rich, full-bodied, leathery, and are marked by flavours of dark fruit and spice with good ageing potential. Each grape variety brings different characteristics to the final blend of the wine. The Grenache brings elegance, flavours and aromas of sweet fruits and a touch of spice. The Shiraz gives dark fruit, spice and savoury nones. And the Mourvèdre brings rich fruit, power, spice and smoke flavours, and adds tender floral aromas of rose and violet. The GSM wine has become one of the benchmarks of Australian wine production recognised all over the world.
