Mitchell produces Shiraz and Rhône-style blends from Clare Valley, a region in South Australia's Mount Lofty Ranges known for structured red wines and cool-climate intensity. The winery's McNicol Shiraz and Auburn Hills Shiraz showcase the region's signature dark fruit and spice character, while the GSM Red—a blend of Grenache, Mourvèdre, and Sangiovese—reflects the broader Mediterranean palette that thrives in Clare Valley's terroir. These wines have been assessed by Wine Enthusiast, Wine Advocate, Wine Spectator, and Decanter.
