In principal, one goal of anyone making wine naturally - organic, biodynamic, or anywhere in between - is heightened expression of terroir. I'm of the opinion that the success of the venture is most perceptible when one evaluates it across the boundaries of individual domaines and regions; in general, one might say, natural wines tend to reflect more dramatically the vicissitudes of the vintage and the composition and exposition of the soil. This is because, when compared to the panoply of invasive techniques available to the contemporary winemaker, natural winemaking is a fundamentally subtractive process. It is, at least in part, a resistance to overcorrection of naturally occurring traits.
Nevertheless, when we use terms like "non-interventionist," we risk obscuring the fact that winemaking itself is one big intervention. What we taste in a glass remains a product of the individual habits and customs of a given estate. Evaluating wines is always a more or less informed stab in the dark about which traits come from the whims of nature and which come from the whims of man.
This brings me, finally, to my conflicted feelings about Cascina delle Rose, a 3ha organic Barbaresco estate we visited in Piemonte this past August. The estate had come highly recommended from two different sets of friends - a surprise, since despite having tasted the region's wines pretty exhausively, I'd never heard of them. Estate owner Giovanna Rizzioli was a marvelous hostess, intelligent and expressive, and the best of the wines we tasted reflected the same qualities. There was, nevertheless, across the range of wines, a rigidity of style that felt determined by something other than the terroir of the estate's 3ha of vineyards. (Cue darkness, stabs.)
