I like the taste of this:

Still, if the wine is being transported half way across the world to a region where wine grow perfectly well, that counteracts the gains.
It has become fashionalbe in some quarters to sneer at organic cultuvation. We did a long hike down the mid-Loire. There were dramatic differences in flora and fauna in areas of conventional viniculture compared to ones following organic or biodynamic principles. We tasted some of the latter’s produce. To be honest, we could not tell any great difference from ‘ordinary’ ones but that is only one element in the sustainability jigsaw. That said, the best wine I’ve ever tasted was indeed organic, a local wine in a restaurant in Biot in souhtern Provence, not far from Nice. Sometimes it is all gain!
