Barossa Valley Estate GSM is a classic Australian red wine blend from one of South Australia's most celebrated wine producers, founded over 170 years ago in the iconic Barossa Valley. GSM stands for Grenache, Shiraz, and Mourvèdre — the three traditional Rhône-style grape varieties that together create this expressive, food-friendly red.
The wine delivers an earthy, fruity nose with flavors of cherry, raspberry, blackberry, and plum, accented by hints of licorice and subtle oak. Medium-plus body with vibrant acidity and a long, balanced finish make this a versatile everyday red with outstanding quality for its price. The blend is slightly off-dry, with ripe fruit taking center stage alongside gentle tannins.
Sourced from the Barossa Valley's unique microclimate and ancient red clay soils — renowned for producing some of Australia's most acclaimed reds — this GSM showcases Grenache's soft fruity richness, Shiraz's spice and depth, and Mourvèdre's earthy structure. Pairs beautifully with beef, lamb, hard cheeses, and tomato-based dishes. Sold individually as a 750ml bottle (cases of 12 available).
