Copper as the saviour of viticulture, but at what cost?
As a geologist, my fieldwork regularly has me wandering through vineyards in warm countries. When this happens, I frequently ask myself if and how geology affects these vines. The winemakers themselves are often convinced of the importance of their specific soil on the taste of the wine they produce. However, there is no simple connection, as I already discussed in detail with my colleague Denise Maljers and oenologist Stan Beurskens. There is a lot involved in making wine; take the use of copper sulphate to prevent leaf mould and rot, for example. This also applies to organic wine, as copper sulphate is a natural product. But why is copper sulphate used? And what are the consequences for the soil? Curious what Geert-Jan will discover? Read it (in Dutch) in his blog.
