We already have, not if you are France or Italy of course. I do own quite some land, but I was not able to plant in there, because of quota.
70% of wine consumption in Czech republic have to be imported and we were not allowed to plant new vineyards. The rules changed last year and we can plant up to 1% of our allowed area now. Still not enough.
Because of EU enforced quota. Even if your land is in vineyard apellation place you can't plant any new vineyard. This rule was enforced as we were joining the union, it is basically way to ensure big producing countries with over production have enough of market to sell their product.
Local producers are able to sell all of their wines without much problem and there is demand for more, but there is nothing we can do about it. Prices of vineyard land did grow 400% over last 10 years and there is huge consolidation going on. Not great place to be independent winemaker with expansion plans.
