Here is a snippet that the moderator Moley posted on his how to make WOW guide:
Eventually, the bubbling will slow right down and stop, and hereâs where you have to start to learn one of the hardest, but one of the most important lessons in winemaking - patience. Donât try to rush it, leave it for another week. Here comes the science:
Yeast turns sugar into alcohol plus carbon dioxide, but in between it makes other chemicals called aldehydes. If you try to rush it you will get an alcoholic drink which will get you plastered but might upset your guts and leave you with a headache. Give it a bit more time and the yeasties will finish clearing away those aldehydes and you should end up with a wine which you can be proud to share with your family and friends.
I know it's cider you're making but it's the same principle
Hope this helps
