Sulfites? Many wines have them thrown on the grapes to kill the natural yeasts so that they can then add a particular yeast.
No wild fermentation? I like the premium wineries in South Australia that have open concrete vats.
Apparently suphites are a natural byproduct of fermentation though that level is very low. Add to that its use as a fungicide.
