For wine enthusiasts, artisanal wine is about continuous variation and the singularities that emerge from those variations. Wine enthusiasts devote most of their attention to tracking variation and assessing it. Differences between regions, varietals, vineyards, winemaking styles, weather and climate variation, soil variation, and bottle variation are of primary aesthetic interest. Life, vitality, is also fundamentally about variation. This shared connection between life and wine is the key to understanding wine’s expressiveness. The art of winemaking is basically the art of expressing vitality. I make the case in my column at Three Quarks Daily.
