FOLLOW THE INSTRUCTIONS!!! If this is your first kit wine and it came with instructions and it is from a reputable manufacturer, your wine will turn out very well. If you stray from the instructions, the results can not be gaurenteed.
I have mad many, many kits and have neveer had one turn out bad.
Patience, Patience, Patience. If you are a home brewer, you should already have this ability.
FOLLOW THE INSTRUCTIONS!!!
