Laser Engraving Options Overview
  • Let the Percolating Begin!
  • An air-lock, sometimes called a fermentation lock - is a small device used in brewing beer or in making wine. When filled partially with water, it acts as a water trap allowing carbon dioxide to be released. When inserted into the bung of the oak barrel, it allows the gases caused by a fermentation to literally percolate through it and then, out of the barrel.
  • Air-locks also play a vital role in protecting your wine or brew during 'secondary fermentation' when the contents become most susceptible to contamination from outside sources.
  • It's easy to use! Simply attach the air-lock by placing its stem into the hole of the rubber stopper and then place the rubber stopper into the 3/4" bung hole of the oak barrel. After you have the air-lock in place, fill it approximately half full with water. Be sure to put the cap back on the air-lock. The cap has tiny pinholes that allow the gasses to make their way out.
