Is there a website that has some sort of a database of all the Extract's Breakdowns? When I go to Northern Brewer they give a pretty good description there of their stuff and what their extract is made of, what it should be used for, etc. I didn't know if there is a database that has all different sorts combined? Just would liek to have one source when figuring out recipes instead of jumping from vendor to vendor to try and pinpoint my "flavors".
