Vineyard owners love to talk about unchanging traditions. But over the decades, the style of their wines has probably changed.The world of wine likes to tout the traditional aspects of winemaking: the long history, the sustainable farming practices, the low-tech methods that have been unchanged for millenia. And to a great extent all that is true. I do not know of an industry where the environmental impact is so closely observed as in wine grape growing and winemaking. Nor do I know of any human endeavor today where the advances of science have had so little effect overall on a craft, despite the research and science that have gone into it in the last 50 years. Most dedicated winemakers have in fact marched away from the technological approach.
