I
n homebrew news, the airlock on my Saison blew off on Friday afternoon, requiring me to leave a conference early to clean up the kitchen. See, as yeast eats sugar, it produces foam and gas, which has to go someplace. Generally a simple airlock will suffice (see photo), allowing air to leave the carboy but not re-enter (oxygen is the leading cause of bad beer!). I'm guessing all the extra sugar I added was to blame, and it couldn't leave the container quick enough, so it forced the lock (and the extra foam) to shoot out the top, and onto my floor and wall. So from now on I will use a blow off tube, which goes from the carboy into a bucket of water. Lessons learned.
