I started a batch of Brew King's International Australian Shiraz this weekend in a 6+ gallon carboy. Within a day it was foaming through the airlock. The airlock spewed wine for a few hours. I tried a few times to rinse the airlock with tap water and put it back on the carboy but ended up installing a blow tube which solved the problem. I rinsed the blow tube with One Step sanitizer before using it.
My question is - in the above scenario is there much chance of contamination? The fermentation had been going pretty strong before the foam over. I'm going to keep my fingers crossed!!!
Thanks for any help, ff
