Powell & Son Riverside GSM 2023

GSM blends combine Grenache's bright fruit and spice, Shiraz's structure and depth, and Mourvèdre's earthy complexity to create wines with greater balance and complexity than any single variety could achieve alone. This Barossa expression showcases how these three Mediterranean varieties complement each other, with the textured, savoury style indicating careful winemaking that allows each grape's character to shine while creating a harmonious whole.

The Barossa's warm, dry climate and diverse soil types mirror the Mediterranean conditions where Grenache, Shiraz, and Mourvèdre originated, allowing these varieties to reach full phenolic ripeness while retaining natural acidity. The region's old vine Grenache and Mourvèdre plantings, some dating back over a century, contribute concentrated flavours and complexity that younger vines simply cannot match.

Serve this GSM at 16-18°C to highlight its textured, savoury character and bright fruit flavours of blackcurrant, cherry, and raspberry. The medium body makes it versatile for food pairing - try it with grilled lamb, Mediterranean dishes with herbs, or aged cheeses where the wine's complexity won't overpower the food but will provide complementary savoury notes.

This style descriptor indicates the wine has substantial mouthfeel with fine tannins that create texture rather than harsh astringency, while savoury elements like herbs, spice, and earthy notes balance the fruit sweetness. This suggests traditional winemaking techniques that preserve the natural character of the grapes, likely including some whole bunch fermentation or extended skin contact to develop complexity.

The 2023 vintage is young and likely drinking beautifully now, showcasing fresh fruit flavours and the wine's natural vibrancy. However, quality GSM blends from the Barossa typically develop additional complexity over 5-8 years, with the Mourvèdre component particularly benefiting from cellaring as it integrates and softens, while the Grenache maintains its fruit character and the Shiraz provides structural backbone.
