I've tried a couple of wine kits now but have been rather put off by the instructions with each. They're very basic and not very detailed, so it's hard to tell what might have gone wrong if the wine doesn't come out the way you hoped.
Oh that stinks! I hate it when you don't have good directions for something new you are trying. Did you look online? Sometimes you can find things on the internet that are better than what comes with the kit.
