Key for me is are the pesticides and additives beyond yeast ending up in wines..
"Yet, as natural wine advocates point out, the way most wine is produced today looks nothing like this picture-postcard vision. Vineyards are soaked with pesticide and fertiliser to protect the grapes, which are a notoriously fragile crop....The modern winemaker has access to a vast armamentarium of interventions, from supercharged lab-grown yeast, to antimicrobials, antioxidants, acidity regulators and filtering gelatins, all the way up to industrial machines."
There is organic wine. It'll still contain lab-grown yeast (to ensure quality) but gets rid of the additives. It's quite expensive (as grapes are fragile) and not very common but can be found in a lot of supermarkets by now.
