Gibbston organic wine trial proves a success

A three-year trial has shown it’s reasonably simple to convert to organic wine production in Central Otago, provided there’s the desire to do so and the financial backing, Gibbston Valley Wines (GVW) vineyard manager Grant Rolston says. GVW, with Wither Hills in Marlborough and Mission Estate in Hawkes Bay took part in the national organic grape-growing trial. The results will be presented at New Zealand’s first national Organic and Biodynamic Winegrowing Conference, in Blenheim next week.
