Abstract

Organic and biodynamic viticulture is forecast to grow at over 11% per annum yet there is little information on the benefits or otherwise that can be attributed to these systems of grape production. With industry funding, a six year trial at McLaren Vale in South Australia investigated the changes in soil health, fruit production and wine quality. Organic and biodynamic production led to improved soil quality, with more soil organisms including much greater earthworm populations. Wine quality was also improved, but in the absence of price premiums, this was achieved at a financial penalty to the grower through reduced yields and increased production costs.
