McLaren Vale GI
Permitted Varieties
McLaren Vale GI
Overview
McLaren Vale is one of Australia’s most historic and diverse wine regions, producing exceptional Shiraz, Grenache, and increasingly celebrated Mourvèdre from vineyards that span an extraordinary range of terroirs just 35 kilometers south of Adelaide. Established as a GI in 1997, McLaren Vale’s maritime influence distinguishes it from the Barossa Valley to the north, producing wines that combine richness with freshness and structure. The region has emerged as the center of Australia’s GSM (Grenache-Shiraz-Mourvèdre) movement and is increasingly recognized for its terroir diversity, with over 40 distinct soil types creating wines of remarkable variety.
