I have a technical question about my wine list that I hope you can help me with.

A winemaker says he does not spray any chemicals on his grapes and says he is “natural without compromises”. But he uses copper and sulphur, as well as treatments based on propolis. So I’m not sure if he would be organic or natural or sustainable. Can you give me some guidance? He’s in Italy, not the US by the way.
