Hi guys, I am completely new to brewing. My girlfriend got me a small personal brewing kit a while ago and we went through the process of getting it into the fermentation process. Well, that process has lasted a little longer than it should have. It has been sitting in a glass fermentor for a little over a month and a white mold has formed toward the top of the jug. I just wanted to know if the beer would still be safe to bottle and drink or if the batch has been infected and ruined.
