This jar is ideal for fermentation

You can use this jar to brew your kombucha, kefir, tepache, fruit wines, and more.

  • Volume suitable for many fermentation uses.
  • Wide opening for easy use and cleaning.
  • Quality glass offering effective resistance.
  • Plastic cover included (does not rust like metal ones).
