15 liter narrow mouth glass demijohn with protective plastic basket, clip on airlock, lid and cleaning brush. Ideal for fermenting approximately 3.5 gallons of beer, wine, cider or other beverages while leaving proper headspace.
This narrow mouth glass demijohn with plastic basket from North Mountain Supply is a versatile fermenter sized for small to medium batches. With a total capacity of 15 liters (about 3.97 gallons), it is typically used to ferment around 3.5 gallons of wine, beer or cider while still maintaining the headspace needed for active fermentation.
Each set includes:
15 liter clear glass demijohn
Durable plastic basket with handles
Clip on airlock
Matching lid
Cleaning brush
The clear glass construction allows you to visually monitor fermentation progress, sediment formation and clarity over time. The narrow mouth design works well with standard stoppers and airlocks, making it easy to control air exchange and protect your batch from unwanted contaminants.
The rustic style plastic basket serves several purposes:
Protects the glass from minor bumps and contact during handling
Provides integrated hand holds for lifting and moving full containers
Helps support the demijohn during storage and fermentation
This setup is ideal for:
Homebrewed wine, beer and cider
Mead, hard seltzer and other small batch fermented beverages
Experimenting with new recipes or flavor additions in 3 to 4 gallon ranges
For best results, always remember to leave sufficient headspace at the top of the demijohn during fermentation, typically about 2 to 3 inches below the bottom of the stopper or airlock. This helps accommodate foaming and CO2 release during the most active stages.
A few notes on the glass and components:
The demijohn is made from blown glass, and small bubbles or variations in the glass are normal and not considered defects
Brush and lid colors may vary depending on production runs
The included cleaning brush is sized to help you reach inside the vessel and keep the glass surface free of residue between batches
