I will try to describe this the best I can. I have a Canadian Ale in the secondary. I racked it over about 2 weeks ago. Within the last 2 days a white ;ooking scum formed on the inside wall of the carboy??? Looks real thick on the bottom of the carboy. I opened it and it smelled fine. I will try to a picture and post it. If was contaminated would ther be a bad smell??
Brew it Drink it Brew MORE!!!!!
