Why Choose Dbgogo S-Type Twin Bubble Airlocks?

Airlocks Are Simple and Important Devices

You can monitor the brewing temperature in time by using the temps strip, they are easy to read; The dust cap with gas venting hole will vent the co2 out and the airlock will not let oxygen enter your brewing bucket by simply filling some water into the airlock.

  • Keep undesired microorganisms away
  • Reduce oxidation (oxidized beer tastes stale at least, some say like cardboard or worse)
  • Allow you to measure how much fermentation is taking place (i.e. how many bubbles per minute)
  • The bubbles are formed, then co2 will escape through the water.
  • If it fails to bubble, it means that the air pressure inside the bucket or carboy isn't high enough. This easily happen if the lid isn’t fully closed or perfectly sealed.

Use a 3/8 bit to gently drill through top of the bucket. Seen here on a 2 gallon food grade bucket from my local home improvement store. May all your brews & ferments be a roaring success. 🦁

Worked as described but the stoppers were a bit tricky to install I lost two of them inside the bottle by pushing too far to get a good seal. There are now like a ship in a bottle 🤣
