We photographed this scene one evening a few weeks ago near Chinon. This is a typical vineyard in early spring, with vines pruned to a single leader. No sign of leaves yet -- it was too early and the buds are tight little buttons, just as they should be in late March. The winemaker has very sensibly let the grass grow under the vines rather than apply a herbicide. The grass absorbs excess moisture and creates a microclimate at low level which benefits the vines. It also means that you can work amongst the vines without churning up the wet winter soil and risking the vine roots becoming exposed due to erosion.
