Key Moments

You don't need a starter culture to ferment vegetables

All plants growing in soil naturally host lactic acid bacteria, so you never need to buy a starter culture for vegetable fermentation. The bacteria are already present on the vegetables themselves, making store-bought lactobacillus packets an exploitative product.

"All plants growing out of soil on planet Earth are host to lactic acid bacteria. And so if we create the conditions in which the lactic acid bacteria can thrive, they are always there to do so."

Sandor Katz's five tips for beginner fermenters

Fermentation revivalist Sandor Katz shares five practical tips: don't be afraid, understand the environmental conditions you're creating, don't overthink simple processes, experiment freely with different vegetables and seasonings, and be creative incorporating fermented foods into your diet.

"Do not be afraid. Do not project all of the anxiety you've ever had about bacteria onto fermentation. Understand that these are ancient practices that have been tested by time and that they are extremely safe."
