Awhile ago I made a coffee porter and during primary, the airlock blew straight off, even using a 6.5 gallon carboy. Gunk everywhere. I learned my lesson from then on that I should use a blow off tube most of the time. Better safe than sorry.
My question though is regarding the set up of a blow off tube. The tube fits snugly into the primary and is leading out into a 5 gallon stainless steel pot. I did not put any fluid in the pot, no sanitizer, no water, nothing. There has been a bit of blow off, the top of the carboy is coated as well as the beginning of the blow off tube in the fermenter. Only a bit leaked out, hardly enough to cover the blow off tube in the pot. Since I didn't use any water or sanitizer in the pot, is there any risk of contamination?
