I'm no doubt naive, but isn't a key idea behind organic and biodynamic agriculture to increase nutrient presence in the vines' rhizosphere by promoting healthy communities of decomposing organisms and soil animals? Their activities are supposed to distribute nutrients (especially nitrogen) continuously at a fine spatial scale, where vines' roots can get at them easily. All else equal, vines' easy access to these soil-borne growth supplies, you'd suppose, would cause early, rapid annual growth, with maturation of stems and fruit sooner than in soils where nutrients are delivered only occasionally and from above. Intense decomposer activity would be consistent, at least, with Eric's observations of rapid pruned shoot decomposition.
Tangentially, supposing this simplified account to be ball-park accurate, it would tend to exclude nutrient scarcity from the category of vine-stressing conditions that notionally produce better wines.
