I was going to mention the same thing in reference to Champagne. If they all had the ability to heat their vineyards in efforts to fight the frost, I for one, would not argue.

Personally, I am losing more terroir-ic faith as the days go. Wine has become so homogenized, the sense of terroir has been diminished (generally speaking).

I say they should shield their vineyards; heat them; net them; crop them; pare them; etc. Do whatever it takes to give the best quality and make the most money for themselves.

You know the second-tier and third-tier won't be losing any money. Right?
