If you are interested in preserving and fermenting beverages, you have probably come across the demijohn – a glass vessel used for fermenting and aging liquids like wine, mead, or beer. Piercing a demijohn is an essential skill to master for successful fermentation. In this beginner’s guide, we will walk you through the step-by-step process of piercing a demijohn for your next beverage project.

What You Will Need:

  • A demijohn (glass fermenting vessel)
  • A demijohn bung or stopper
  • A rubber or silicone grommet
  • An airlock
  • A drill with a diamond or carbide bit
  • A marker or tape

Step 1: Marking the Spot

Begin by placing your demijohn on a stable surface and identifying the area where you want to pierce it. It’s crucial to pierce the demijohn at a suitable height to allow for proper liquid and airlock insertion. Use a marker or tape to mark this spot.

Step 2: Preparing for Drilling

Put on your safety goggles and gloves to protect yourself from any potential shards. Ensure your drill is fitted with a diamond or carbide drill bit suitable for glass. These specialized bits are designed to minimize the risk of cracking or shattering the demijohn.

Step 3: Drilling the Hole

Gently place the tip of the drill bit on the marked spot and start drilling. Remember to apply consistent but gentle pressure to avoid accidentally breaking the glass. Keep the drill steady and progress slowly until you penetrate the glass completely.

Step 4: Securing the Grommet

Once the hole is drilled, remove any glass shards and debris. Insert the rubber or silicone grommet into the hole, ensuring a snug fit. The grommet acts as a seal for inserting and securing various accessories.

Step 5: Inserting the Airlock

Take your airlock and gently push it into the grommet. The airlock will allow the release of excess carbon dioxide during fermentation while preventing any air or contaminants from entering the demijohn.

Step 6: Testing for a Secure Seal

Give the airlock a slight twist or pull to ensure it is securely attached. You do not want any potential leaks during the fermentation process. If it feels loose, double-check the grommet’s fit and make any necessary adjustments.

Step 7: Sanitizing and Filling the Demijohn

Before filling your demijohn with your chosen beverage, it’s crucial to sanitize it thoroughly to prevent any unwanted bacteria or yeast growth. Follow your preferred sanitizing routine, rinse well, and then carefully pour your prepared liquid into the demijohn.

Step 8: Sealing the Demijohn

Finally, seal the demijohn with a suitable bung or stopper that fits securely in the vessel’s neck. This will complete the setup, creating an airtight environment for fermentation to take place.

With these steps, you should now have a successfully pierced demijohn ready for preserving and fermenting your favorite beverages. Remember to take necessary precautions and always follow proper sanitizing techniques for a successful fermentation process. Enjoy your journey into the world of beverage preservation!
