Organic producers are criticized for their use of copper in the vineyards. The EU allows 6 kilograms of copper per hectare and per year for organic producers, as we mentioned recently (Organic viticulture: How do you use less copper?).

Gottfried’s vineyard gets quite a lot of rain during the year, 800-900 mm, but he usually can cope with between 2 and 2.5 kilograms of copper.
