Straight to the point...my immersion chiller hose came off the copper chiller today while chilling and before I could fix it about 1/2 gallon of un-sanitized tap water went into my brew kettle post boil while the wort was about 160 degrees. I've never had an infected batch before and am wondering if this is going to be the first. I would have boiled again for a bit but my propane ran out with 5 minutes left in the boil so that wasn't an option. Has anyone had a similar issue like this? If so how did the beer come out? The yeast were prime and ready to go...I began to see activity about an hour after pitching. Any thoughts?
