After doing research online, I have read that using screw caps is superior to using corks when bottling wine. It also seems to be a cheaper option. My question is, which kind of screw top is best to use for long term storage? I have seen Stelvin brand screw caps, which seem to be a good choice. I also have seen the standard 28mm metal screw caps. What made me notice the Stelvin caps, is that they have a quality seal built in. But I could not tell if you need a certain piece of equipment to put these tops on. Has anyone tried this brand? And how do people feel about the standard 28mm screw caps that most homebrew stores carry?
