I made a batch of coffee roasted porter and pitched in the yeast, which I used a starter. Well between midnight and 9am it blowed out, there was porter on the bucket the 3 gallon carboy was sitting on and still some in the air lock. I figured with the pressure being elevated still and with minimal air access that I could refill the airlock with vodka and let it finish working for the rest of the three weeks. If I see any scum on top or cloudy build up, I know it got a bug.
Is my course of action sensible?
