This is a terrific discussion.
I agree with Cristof. What about the average wine drinker? They are our guests. I believe that they do actually care that a wine is made from organically grown grapes, hand-picked with love, or biodynamically farmed. But do they really care when they drink a wine? If the wine has the profile that they gravitate towards, does the guest care if the wine is an elephant or not. Manipulation in wine is like the a chef making green beans taste sublime.
Last summer I spent six weeks in Beijing serving wine to dignitaries during the 2008 Beijing games. I learned that since there is no regulations for wine authenticity in China, the wine that said "Made in China" could have been manufactured in China with juice from Chile. I found these finished wines to be disjointed, unbalanced and unappetizing. The Chinese thought the wine was terrific. Who is correct?
Technology can be an asset. Stainless steel tanks in wineries, Cryovac machines in kitchens. Is micro-ox a positive or negative advancement?
But when I drink wine, I want the wine to be a pure expression of a time, a place and a person who made the choice to put the wine into a bottle.
