What is the standard pickling brine ratio?

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.

What vinegar should I use for pickling?

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.

How much brine do I need per jar?

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.

What is the difference between quick pickles and preserved pickles?

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.

Can I reuse pickling brine?

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.

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.
