But I have no idea how to make an extract. It seems like you just put your flavoring items in some alcohol and let it sit. So how much vanilla do I use to get it to be a really strong vanilla flavor? I have vodka 40 ABV and grain alcohol 75 ABV, don't know which one to use or how much of it to use. Also don't know how much to use in a 5 gal batch or when to put it in.
