I'm talking about growing the vine not processing the harvest/marketing it. google biodynamic wine and see how prevelant it is. When comparing high value crops grapes are one of the easiest to grow biodynamically. Making a fine wine is alot different than growing grapes.
I really think that you should check yourself- I have been around vineyards my entire life.
edit.
And in reference to my post about it being 'easy' in the USA, it was in the context of producing a more consistent grape harvest due to the available irrigation during the growing season.
Ahhhh - just to clarify for you. If you just grow a vine, you will never produce a viable grape crop. Just as I, a grape grower for over 35 years, am experiencing a learning curve with this hobby of a crop that we all grow here. And I understand soil, water and fertilizers better then most. Grow a lush and beautiful vine and you will produce no viable fruit. It's a balance that doesn't come from a text book but takes YEARS to understand and learn, since you don't get 4 crops a year.... you get one.
But don't take my word for it, instead of "just being around a vineyard", just sink all your dough in a vineyard and go broke. I've forgotten more, in 35 years of growing over 20 various varieties and selling over 300 million Lbs. of grapes to supermarkets all over the world, then you'll ever know. You'd be better off arguing with your mom or dad. Or impressing someone who doesn't know any better.
biodynamic. Pffft.
