So how can it be decided that a certain scent in a wine comes from a piece of land rather than a winemaking technique or a strain of yeast?
Oh, that can be decided, Otto. Not easily, but it can be determined by some careful testing. Simplest would be to take the same grapes as fermented by several different strains of yeasts and assessing the aromatic variations. People at UC Davis, and the U of Bordeaux and Montpellier do this all the time. Heck, individual wineries and winemakers and testing labs do this all the time.
Considering how many variables there are in a wine all of which produce aromas, I am very wary of accepting that one scent is inevitably a scent deriving from the parcel of land.
There you go. No problem agreeing with that.
It would to me seem that with all these variables, we cannot talk of terroir at all - only typicity. We all know that Bordeaux left bank tastes like Bx left bank, but I don't think we can say this is due to the terroir (whichever way defined) or to the grapes, but due to the whole influence of grapes, soil, climate, yeasts, human intervention, etc. ad inf.
Yep. Pretty much my view all along, and oft expressed: each wine can be assessed with the consideration of the three elements of variety, sense of place (since you don't care for terroir), and the winemaker's influence (or style). It's like a pie chart, with the movable sections adjusting to the variable influences of the three elements. An oaky, buttery Chardonnay, for instance, would likely have much more of the pie going toward the winemaker's influence. A Chablis would likely have much more leaning toward the sense of place and the varietal tipicity. Changes with every wine---the only thing of any importance to me is considering the three elements and how they interrelate, not precisely defining where the dividing lines are---that's a foolish chase.
But what I wonder about is why we should care about this! What I like about typicity is that it gives diversity to the world of wine, yet makes it a comprehensible whole with a unifiying theme in a certain area. Whether the similarities in an area are caused by the land or generally used techniques of native yeasts is irrelevant IMO - it serves no real purpose as long as what is in the glass seems typical to the area. How the typicity of an area is defined is of course an interesting question, but one which, if I've thought this out correctly, just cannot be answered.
Bite your tongue, you bad boy! People that hang around this place probably like talking about (or talking about talking about) wine as much (more?) than they do actually drinking the wine. Are you trying to deprive these good people (and I include you and me in that group) one of their key forms of amusement???
