I mean the argument is you're going to lose any sense of Terroir...and that is a huge amount of the cost at the high end of the market. Sure, you pay for taste, but you also pay enormously for origin and provenance.
Absolutely agree. I am not going to convince people that wine origin doesn’t matter. But I believe that 15% of grapes from a ‘Napa Valley Cab Sauv’ labeled wine can be grown outside of Napa. 25% if the wine is labeled as a ‘North Coast Cab Sauv'. So maybe the project is good for these types of situations.
