Salt percentage
3% salt — brine-pickle standard
Clearly salty — the brine bite you expect in a deli pickle. Most traditional half-sour recipes use 3-3.5% brine (30-35g salt per 1000g water).
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.
All salt grains
| Grain | Grams | Teaspoons | Tablespoons |
|---|---|---|---|
| Diamond Crystal kosher | 30 g | 10.56 | 3.52 |
| Morton kosher | 30 g | 6.25 | 2.08 |
| Fine sea salt | 30 g | 5.27 | 1.76 |
| Pickling / canning | 30 g | 5.45 | 1.82 |
Safety and use at 3%
The reliable middle for brine-pickling at room temperature. NCHFP recommended floor for brine-pickled cucumbers. Provides safety margin for typical kitchen (65-75°F) at 7-14 day ferment lengths.
Technique notes
For brine-pickling: calculate 3% of total brine weight, not of vegetable weight. E.g., 1kg water = 30g salt. For dry-salting: less common at this %, but used for onions + harder root vegetables.
Typical ferments at 3%
- brine pickle half sour
- giardiniera
- cauliflower brine
Frequently asked questions
How much salt is 3% for fermentation?
3% salt = 30.0g salt per 1000g vegetables. For 500g: 15.0g salt. Multiply vegetable weight by 0.03. Use non-iodised salt and weigh in grams — teaspoon equivalences vary by salt grain type.
Is 3% salt safe for fermentation?
The reliable middle for brine-pickling at room temperature. NCHFP recommended floor for brine-pickled cucumbers. Provides safety margin for typical kitchen (65-75°F) at 7-14 day ferment lengths.
