Let it bubble, on purpose

Ferment your own tangy, living foods, starting with one jar.

A friendly, practical guide to fermenting food and drinks at home for people who've never let anything bubble on the counter on purpose. We cover the simple science of how salt and good microbes keep ferments safe, your first batch of sauerkraut and a jar of crunchy pickles, brewing kombucha from a SCOBY and culturing your own yogurt and kefir, the handful of jars and tools you actually need, and how to tell healthy ferments from the ones to toss, so you go from a bag of cabbage to a fridge full of tangy, living foods you made yourself.

Fermentation Brine Calculator

Get the exact salt weight for a safe brine, by brine-only or total-weight method, for pickles, olives, kraut, and kimchi.

Use 20 g of salt (roughly 3.4 tsp).

Never go below 2% for vegetable ferments. Use non-iodized salt (pickling, kosher, or sea salt without anti-caking additives), and use filtered or boiled-and-cooled water if your tap water is heavily chlorinated, since chlorine can slow fermentation. A scale beats teaspoons; the tsp figure is a rough backup only.
