Pickling Brine Calculator
Calculate vinegar, water, sugar, and salt quantities for pickling brine by jar size and count.
How We Calculate This
This calculator estimates the total brine volume needed based on your jar count and size, then calculates the individual ingredient quantities using standard pickling ratios.
Standard Brine (per 500ml)
- Standard: 250ml vinegar, 250ml water, 2 tbsp sugar, 1 tbsp salt
- Sweet pickle: 250ml vinegar, 250ml water, 4 tbsp sugar, 0.5 tbsp salt
- Quick pickle: 250ml vinegar, 250ml water, 1.5 tbsp sugar, 1 tbsp salt
Jar Filling
- Brine fills approximately 45% of total jar volume
- Vegetables fill the remaining 55%
These are typical UK table-pickle ratios and a representative 40–50% brine-fill assumption (you can override both under Advanced options for your own recipe). They are flavour guidelines, not a hard rule. The one figure that is safety-critical is acidity: for shelf-stable preserving, always use vinegar of at least 5% acetic acid and keep the vinegar fraction at 50% or more of the liquid. Quick (refrigerator) pickles are not heat-processed and must be kept in the fridge. When in doubt, follow a tested recipe and the FSA guidance on home preserving.
Frequently Asked Questions
A standard pickling brine uses equal parts vinegar and water (250ml each per 500ml total), with 2 tablespoons of sugar and 1 tablespoon of salt per 500ml of brine. This provides a balanced flavour with enough acidity for preservation.
Use vinegar with at least 5% acidity. White distilled vinegar gives the cleanest flavour and does not discolour vegetables. Malt vinegar is traditional for British pickles like piccalilli and pickled onions. Cider vinegar adds a mild fruity note.
Brine typically fills about 40-50% of the jar volume, with the rest being vegetables. So a 500ml jar needs approximately 225ml of brine. Always ensure vegetables are fully submerged in the brine — if not, top up with a little extra vinegar.
Quick pickles (refrigerator pickles) are not heat-processed and must be stored in the fridge. They are ready to eat within 24 hours and keep for 2-3 weeks. Preserved pickles are sealed in sterilised jars and can be stored in a cool dark place for up to 12 months.
It is not recommended to reuse brine for preserved pickles as the acidity and salt concentration will have changed. For quick refrigerator pickles, you can reuse brine once. Bring it to the boil first and use it within a few days.
