Quick vs fermented
Quick pickles are preserved by vinegar acidity and stored cold. They are crunchy and fast but not fermented — no live cultures.
Quick pickles keep cold for weeks. Fermented pickles build live cultures and keep longer, cold.
Salt-type note
Use non-iodised salt — fine sea salt runs about 18 g per tablespoon. Weigh whenever you can; the gram figure is the one that travels between recipes.
Estimates only. For water-bath canning, follow a tested recipe for acidity and processing time.
All-purpose brine
Equal parts 5% vinegar and water with about 2% salt. Sweeten for bread-and-butter pickles, or drop the vinegar to ferment instead.
1 L classic → 500 ml vinegar + 500 ml water + 20 g salt. 1 L fermentation → 1 L water + ~35 g salt, no vinegar.

Pickling brine guide
Vinegar for speed, salt for fermentation.
Use the calculator above for the exact ratios. Use the guide below to choose between a quick vinegar pickle and a salt fermentation brine, and to get the crunch and safety right.
Classic quick brine1:1 + 2%
Equal vinegar and water with a modest salt level — the all-purpose pickle.
Sharp deli brine2:1
Vinegar-forward for a punchy, sour bite.
Fermentation brine3–3.5%
Salt and water only — the vegetables sour naturally over a week or two.
Quick-pickle brineequal 5% vinegar + water + ~2% salt
1 L of classic brine is 500 ml vinegar, 500 ml water, and about 20 g salt. Drop the vinegar entirely and raise the salt to ferment instead.
01
The vinegar-to-water ratio for pickling
For quick pickles, the brine is a blend of vinegar, water, and salt, and the vinegar-to-water ratio sets how sharp the result is. Equal parts vinegar and water, a 1:1 ratio, is the reliable all-purpose starting point that suits most vegetables. Lean toward 1:2 for a milder, more cucumber-forward pickle, or 2:1 for a punchy, deli-style bite.
Use vinegar with at least 5% acidity, which is the standard for supermarket white, cider, and wine vinegars. The calculator splits your chosen jar volume into exact millilitres of vinegar and water, and the split bar shows the balance at a glance so you can see a mild brine turn sharp as you change the ratio.
Fast anchors (1 L brine)
Mild 1:2 → about 340 ml vinegar, 660 ml waterClassic 1:1 → 500 ml vinegar, 500 ml waterSharp 2:1 → about 660 ml vinegar, 340 ml water
02
How much salt to add
Salt is part of the brine in both styles, but it plays a different role in each. In a quick vinegar pickle, roughly 2% salt by weight of the total liquid is about seasoning and crunch, because the vinegar is doing the preserving. In a fermentation brine there is no vinegar, so the salt has to carry the whole load and sits higher, around 3 to 3.5%.
Because salts vary so much by grind and brand, the calculator gives you the weight in grams as well as tablespoons. Weigh it where you can — the gram figure is the one that survives switching from fine sea salt to flaky kosher without wrecking the balance.
03The core choice
Quick pickles vs fermented pickles
These are two different preservation methods that happen to share a jar. Quick pickles rely on vinegar acidity: you pour a hot or cold vinegar brine over the vegetables and keep them in the fridge. They are ready in hours to days, stay crunchy, and taste bright, but they are not fermented and contain no live cultures.
Fermented pickles rely on salt and time. A salt brine with no vinegar lets the vegetables sour naturally over one to two weeks as lactobacillus convert their sugars into acid. The payoff is a deeper, more complex flavour and live probiotics. Switch the calculator between the two modes to see how the recipe changes: vinegar disappears and the salt climbs.
Quick (vinegar)Vinegar + water + ~2% salt. Fast, crunchy, fridge-stored, no cultures.
Fermented (salt)Salt brine only, ~3–3.5%. Sours over 1–2 weeks, builds live cultures.
04
Choosing a vinegar
For safe quick pickling, acidity matters more than variety. Any vinegar at 5% acidity or higher preserves reliably; below that, results are unpredictable and not safe for longer keeping. White distilled vinegar is neutral and lets the spices lead, apple cider vinegar adds a mellow fruitiness, and white wine or rice vinegar bring softer, rounder notes.
Avoid homemade or unlabelled vinegars for preserving unless you know their acidity, and never dilute vinegar below the 5% mark in a recipe meant to keep. If you want a milder pickle, change the vinegar-to-water ratio rather than using a weaker vinegar — that keeps the acidity of the vinegar itself where it needs to be.
05
Sugar: dill to bread-and-butter
Sugar is the optional dial that moves a brine along the sweet-sour spectrum. Straight dill and sour pickles use little or no sugar, letting the vinegar and salt dominate. Bread-and-butter pickles, on the other hand, lean on a generous amount of sugar to balance the vinegar into that familiar sweet-tangy flavour.
The calculator offers none, light, and sweet levels for quick pickles so you can nudge the balance without guessing. Add sugar to the brine along with the salt and dissolve both fully before pouring. For fermented pickles, sugar is generally left out, since the point is to let the vegetables sour rather than sweeten them.
06
Mixing and pouring the brine
For a quick pickle, combine the measured vinegar, water, salt, and any sugar, and warm gently until the salt and sugar dissolve. You can pour the brine hot over the packed vegetables for a softer, faster pickle, or cool it first for a crunchier fridge pickle. Either way, make sure the vegetables are fully submerged.
For a fermentation brine, dissolve the salt in the water, cool it to room temperature, and pour it over the vegetables, keeping everything weighted below the surface. The exposed-vegetable problem is the number one cause of fuzzy growth, so a weight or a filled bag on top earns its place in the jar.
07
Keeping pickles crunchy
Soft pickles are the most common complaint, and a few habits prevent them. Start with the freshest, firmest vegetables you can, and trim the blossom end of cucumbers, which carries enzymes that soften the batch. Cold-pack fridge pickles stay crunchier than hot-brined ones, so if crunch is the priority, cool the brine before pouring.
A tannin source, such as a grape, oak, or blackcurrant leaf, or a pinch of black tea, helps firm things up in both quick and fermented pickles. And do not over-soften with heat: if you are hot-packing, pour and cool promptly rather than letting the vegetables sit in hot brine longer than needed.
08
Storage and safety
Refrigerator quick pickles are not shelf-stable. They keep for several weeks to a couple of months in the fridge, but leaving them at room temperature is not safe. To store quick pickles on the shelf, you must use a tested water-bath canning recipe with a verified acidity level and processing time — do not improvise that part.
Fermented pickles sour at room temperature and are then moved to cold storage, where they keep for months. Trust your senses: cloudy brine and a sour smell are normal, but slimy textures, off odours, or coloured fuzzy mould mean discard the batch. When in doubt with any preserving question, follow a tested recipe rather than a rule of thumb.

Quick answers on vinegar-to-water ratios, salt levels, and quick versus fermented pickles.
What is the ratio of vinegar to water for pickling?
A classic all-purpose quick-pickle brine is equal parts vinegar and water (1:1). For a milder pickle use 1 part vinegar to 2 parts water; for a sharp, deli-style pickle use 2 parts vinegar to 1 part water. Use 5% acidity vinegar as the standard.
How much salt goes in pickling brine?
For quick vinegar pickles, about 2% salt by weight of the total liquid gives good flavour. For fermented pickles, use a stronger 3 to 3.5% salt brine because the salt, not vinegar, is doing the preserving. The calculator handles both.
What is the difference between quick pickles and fermented pickles?
Quick pickles are preserved by vinegar acidity and kept cold — they are fast and crunchy but not fermented, so they contain no live cultures. Fermented pickles use a salt brine and time; the vegetables sour naturally through lacto-fermentation and develop probiotics.
Can I use any vinegar for pickling?
Use a vinegar with at least 5% acidity for safe quick pickling — white, apple cider, and white wine vinegar all work. Below 5% acidity is not reliable for preserving. Flavour aside, the acidity percentage is the number that matters for shelf stability.
Do I need sugar in pickling brine?
Sugar is optional. Straight dill pickles use little or none, while bread-and-butter pickles rely on a generous amount for their sweet-sour balance. Add sugar to taste for quick pickles; fermented pickles generally skip it.
How long do quick pickles last?
Refrigerator quick pickles typically keep for several weeks to a couple of months, stored cold. They are not shelf-stable unless processed in a water-bath canner using a tested recipe. Fermented pickles, kept cold after souring, last longer.
