Frequently Asked Questions - Troubleshooting

Everything you need to know about storing and troubleshooting your ferments

  • When stored properly in the refrigerator, fermented vegetables can last 4-6 months or even longer. Keep them submerged in brine and use clean utensils to maintain freshness.

  • If you see mold (fuzzy growth), discard the entire batch. To prevent mold, ensure vegetables stay submerged under the brine and use proper fermentation weights. A little white yeast on the surface is normal and can be skimmed off.

  • Soft vegetables usually result from fermenting at too high a temperature or for too long. Keep ferments at 18-22°C and taste regularly. Adding tannins from grape leaves or oak leaves can help maintain crispness.

  • Yes! Bubbling is a sign of active fermentation. A tangy, sour smell is normal. However, if it smells rotten or putrid, something has gone wrong and the batch should be discarded.

  • Yes! Leftover brine from a successful ferment can be used as a starter for your next batch, speeding up fermentation. You can also drink it as a probiotic tonic or use it in salad dressings.

Meet the Maker

Hi, I'm Tina van der Walt — farmer, fermenter, and firm believer that real food is the best medicine. I live and work on a small farm in Limpopo, where I grow most of the vegetables that go into our ferments. When I'm not elbow-deep in a crock of sauerkraut, you'll find me in the garlic fields, feeding the animals, or experimenting with new fermentation recipes. Fermentastic was born from a simple idea: that gut health starts with what you eat, and what you eat should be real, raw, and alive.
