Grape sorting is extremely important, especially for domaines that don't use sulfites. We must have an absolute faultless quality harvest, if we don't wish to have problems later. We at Domaine Prieuré Roch reckon that 95% of sorting... is done in the vineyard. This is so as to not let any lesser quality grapes into the winery. Then in the winery we make a second sorting, where we eliminate the last berries, which are not totally clean.
