I began the boil for my second brew last night, a Cream Stout, only to realize I had no airlock to use. You'll notice the only airlock I own resting atop my fermenting Apfelwein.
Well, this wasn't a problem in the slightest. Some tubing sliced lengthwise to slide in with the other end submerged in a dish of sanitizer.
This is the third brew (of my life) since the beginning of the month. I bottled an Irish Stout 4/12/08, which is now very delicious. The Apfelwein has been fermenting since Monday 4/21/08, and this Cream Stout just started fermenting this afternoon after last night's airlock improv.
Does anyone else have an easy way of making a check valve/airlock from common tools?
