This yeast nonsense has spun completely out of control.originally posted by Oswaldo Costa:
Mark, if there are descendants on non-native yeasts, and presumably there are most of the time, then the expression of that particular terroir (understood as soil, climate, and microbial life, including yeasts and bacteria) will be slightly less.
Let's stipulate for a moment to your terroir definition (or as the Professor has convincingly explained, your terroir re-definition) to cover the dirt but not the culture of a place. For the reasons I've already gone through, I think there are more things in heaven and earth than are dreamt of in that philosophy, but at the very least I'm willing to admit that there are aspects of terroir so understood that relate to real differences in wine and the reasons people prefer one wine over another one. Exposition, for example, is going to result in real and replicable differences in wine and account for the difference between that perfectly situated mid-slope grand cru and the nosebleed village plot up in the hills that never ripens quite as well and has those coarser tannins. The reason we care about terroir is because the differences in those two sites are interesting to observe and to preserve.
At some point, whoever sits on the self-appointed Supreme Court of Natural Wine decided that because selected yeasts could be used to impart particular flavors and control other characteristics, suddenly native yeast was a part of terroir. The problem is that this decision was reached WITHOUT any demonstration that the difference in the yeast population between, say, La Romanee-Conti and Les Beaux Monts played any part whatsoever in the qualities that make La Romanee-Conti and Les Beaux Monts taste different from one another. Indeed, there has not even been any demonstration that differences in native yeast populations respect in any way the historic boundaries from one terroir to the next (it goes without saying that none of the monks and other figures lost to history who mapped out the terroirs we care about so dearly knew the first thing about microbes). This is a wholly unnecessary dogma. You don't need to make any terroir claims on behalf of yeast in order to oppose the use of designer yeasts to spoof a wine.
Separately...
The more I think about it, the more difficult it seems to be to sustain any definition of terroir that wholly excludes historical tradition. Oswaldo earlier defined terroir as what "come
