Twelve Staves produces wine in McLaren Vale, the warm, maritime-influenced region of South Australia's Fleurieu Peninsula. The winery focuses on two signature expressions: a Grenache that captures the region's ripe fruit character and structure, and a Shiraz that reflects McLaren Vale's capacity for depth and complexity. Both wines have been assessed by major international critics including Wine Advocate, Decanter, Wine Spectator, Wine Enthusiast, and Falstaff. The Grenache averages 90.4 points across prestige ratings, while the Shiraz averages 89.4. McLaren Vale's warm days, cool nights, and proximity to the Southern Ocean create conditions suited to these Mediterranean and Rhône-style varieties, allowing for full ripeness alongside natural acidity and balance.
