Getting started with the fermentation set

Step by step to safe fermentation - without daily venting.

Quick start

  1. 1 Wash and cut the vegetables.
  2. 2 Weigh the salt: <strong>2%</strong> of the vegetable weight (e.g. 20 g per 1 kg).
  3. 3 Massage it in (cabbage) or cover with brine (carrots).
  4. 4 Fill the jar, leaving <strong>2-3 cm headspace</strong>.
  5. 5 Place the glass weight on top - everything must stay below the brine.
  6. 6 Add the silicone lid with valve and gently fix the screw band.
  7. 7 Ferment at 18-22 °C, then store in a cool place.
The valve lid releases gases and the glass weights keep everything below the brine - for clean fermentation and full flavor.

Why ferment?

  • More flavor: Lactic acid gives vegetables a deeper aroma.
  • Longer shelf life: Weeks to months when stored cool.
  • Simple and natural: Just vegetables, salt and time.
  • Low effort: The valve releases gases automatically.
