Ok so this was my first attempt at brewing. Can't wait to actually do it so I can be outside drinking a few brews in warm weather. Anyhow since this was my first brew after 3 days of fermenting and the bubbling stopped my curiousity got the best of me. I opened my bucket several times to see what was going on during the process to learn and understand the process. My question is this other than possible "contamination" is there any other harm that I could have done to the beer? Did I let some magical gas escape or anything. I will do much better bext time!
