Have trouble with any sulphites. I have all the wine making equip including a filter machine and have made 100 bottles of wine. Would love to try and leave the sulphites out but hate to wait 3 months to find out I ruined a batch. Basment stays around 60 degrees in the winter months.
When I started making wine I asked the same question. An experienced wine maker told me that I could leave it out, but the wine wouldn't keep as long and it wouldn't taste like what I expected it to taste like. He was right. So, I guess my answer would be that yes, you can leave them out, but you need to be aware of the effects of doing that.
