Project description
Terroir studies in South Africa have been focussed on the Stellenbosch district and on Cabernet Sauvignon and Sauvignon blanc in order to determine suitable methodology for delimitation of terroirs. This preliminary study has been completed and it is necessary to test the methodology in a different region.

The aims are:
1. to delimit natural terroir units in a selected sub-region of the Robertson valley
2. to determine the viticultural and enological performance of Chardonnay and Shiraz in the selected sub-region of the Robertson Valley
3. to delimit terroirs for Chardonnay and Shiraz in a selected sub-region of the Robertson Valley.
