The soils are predominantly terra rosa soils (over 80%). These soils are shallow with red-brown earth over hard capped limestone. They tend to produce deeply coloured red wines with good structure and backbone that show great capacity for ageing.
The Estate vineyards are predominantly Shiraz, planted as early as 1919. The variety balance grown at Coriole is 65% Shiraz, 10% Sangiovese, 5% Chenin and 5% Cabernet Sauvignon. Other varieties are Fiano, Grenache, Barbera, Montepulciano, Merlot and Semillon. There are in total 25 different vineyards from 90 years old to 3 years old.
Coriole manages most vineyards where fruit is sourced. It also has vineyards in the sub-regions of Blewitt Springs and Willunga.
This year the first moves have been made to organic viticulture. This programme is set to expand in following years.
