Good to hear that the "sulfur" smell has disappeared. I can see from your sig that you are also a homebrewer. I have a feeling that this smell may have something to do with the wine just being a little "green" still. Just like beer, the wine does need time in the bottle to mellow out. These Island Mist kits are basically ready to be drank in 30 days. However, I have found that these kits benefit from an additional 30 days of aging in the bottles. A good two months from start to glass should result in much lower amounts of this "sulfur" smell. I smelled the same thing and was worried about the wine, but it has disappeared after about half the batch is already gone!
