Brine Calculator: Precise, Safe Brines for Vegetables
Set your brine % or end-salinity, choose your jar or total weight, pick your temperature — we'll calculate exact salt grams and give you a clean, step-by-step plan.
⚠️ Educational tool. Always keep vegetables submerged and use clean equipment.
🚀 Quick Start Guide
Weigh
Place jar on scale, tare, add vegetables, cover with water. Note total weight.
Choose Mode
Brine % (2–5% typical) or End Salinity (0.8–2.0% typical target).
Calculate
Get exact salt grams, then follow mixing and submersion steps.
📋 Recommended Brine Ranges by Vegetable
| Vegetable | Brine % Range | Notes |
|---|---|---|
| Cucumbers | 3.5–5% | Higher % for crispness |
| Carrots | 2–2.5% | Mild, sweet ferment |
| Beets | 2–2.5% | Earthy, vibrant color |
| Green Beans | ~2% | Tender texture |
| Garlic | ~3% | May turn blue (safe) |
| Onion | ~5% | Strong flavor |
| Radish | 3–5% | Peppery, crunchy |
| Olives | ~10% | High salt for preservation |

⚠️ Safety & Quality Guidelines
- Use filtered, boiled-then-cooled, or dechlorinated water; chlorine can inhibit desirable bacteria.
- Prefer non-iodized salt without anticaking agents; fine sea salt dissolves easiest.
- Keep produce fully submerged with weights; clean jars and utensils help reduce surface issues.
- When in doubt, throw it out. Red, pink, or fuzzy mold = discard immediately.

🔧 Common Issues & Fixes
Normal during active fermentation. Cloudiness is caused by lactic acid bacteria and yeast activity. If it smells sour and pleasant, it's fine. Learn more →
Choose fresher produce, ferment cooler (15–17°C), or slightly increase salt within recommended range. Consider tannin sources like grape leaves. Texture troubleshooting guide →
Kahm yeast (white film): Skim and ensure proper submersion. Mold (fuzzy, colored): Discard batch. Visual ID guide →
Briefly soak a portion in unsalted water just before eating. Do not store after de-salting. Flavor adjustment tips →
