Salt calculator
Enter your vegetable weight and a salt percentage. We return the exact salt mass in grams, plus teaspoons for each common grain.
Grain matters: one teaspoon of Diamond Crystal weighs half as much as one teaspoon of fine sea salt. Weigh in grams when you can.

About Zucchini
A high-water summer squash that ferments fast but softens easily. Like cucumber, zucchini's ~95% water content makes it prone to going mushy, so it is brined at a higher salt percentage (3.5-5%) to keep the flesh firm and slow softening. Best fermented in spears or thick coins rather than shredded.

Technique
Cut into spears or 1cm coins. Submerge in a 3.5-5% salt brine (35-50g salt per liter of water) with a grape, oak, or horseradish leaf for tannins that preserve crunch; add garlic and dill if desired. Keep fully under the brine with a weight at 65-72°F for 5-10 days, then refrigerate once sour. Firmer at the lower end of the time range.
Salt level notes at 4%
Never use 4% for final dry-salted sauerkraut — way too salty. Only for pre-ferment rinse stages or for dilute brines (kvass) where the resulting beverage is drunk diluted or cooking vinegar.
Safety: Flavour-forward. Ferment will be slower; brine will taste salty. Good for pickles and hot-sauce mashes that need long shelf life.
