Our vineyard didn’t make as much money as surrounding vineyards but it was still self sustaining. More robust demand for organic wines would have made it even more so.
Organic farming has external benefits as well, or rather the absence of negative externalities like harmful chemical run off and less water usage. These aren’t as easily noticed by just looking at market dynamics currently.
All that being said, my understanding is that organic farming isn’t the right choice in all cases. It’s definitely more labor and sometimes resource or land intensive. It takes a certain wealthy consumer base to support it.
