What it is
What happens to a sprig of tarragon left in white wine vinegar for two weeks? The herb's oils slowly migrate into the acid, and the result is a vinegar that tastes distinctly of tarragon, ready to lift a dressing or sauce far beyond what plain vinegar could.
Crafting infused vinegars is the practice of steeping herbs, fruit, garlic, chilli, or aromatics in vinegar to draw out their flavour over days or weeks. The acid acts as both a solvent and a preservative, pulling flavour from the ingredient while its low pH keeps spoilage at bay. The result is a seasoned vinegar that does double duty in dressings, marinades, and finishing sauces.
The method is patient rather than difficult. You pack clean, dry aromatics into a sterilised jar, cover them completely with vinegar, and leave it somewhere cool and dark to infuse. Time does the work; most infusions are ready in one to four weeks, then you strain out the solids. Raspberry, tarragon, garlic, and chilli are reliable starting points, and the colour often shifts beautifully as the infusion develops.
Most people start with a single herb and are surprised how much character it adds. The honest caution is around fresh garlic and low-acid additions, which can carry a botulism risk if not handled properly, so many people use dried aromatics or keep garlic infusions refrigerated and short-lived. A bottle costs little to make and looks striking, which is why infused vinegars make popular gifts.
How it works
The vinegar you choose sets the whole character, so decide first. White wine vinegar is a clean neutral canvas that lets delicate herbs shine. Cider vinegar brings its own fruity backbone. Avoid anything below 5% acidity, because that level both preserves safely and stands up to dilution by the added ingredients.
Pack a sterilised jar with your aromatics: fresh tarragon, thyme, or rosemary, peeled garlic, chilli, raspberries, or citrus peel all work well. Bruise herbs gently to release their oils. Warm the vinegar to just below a simmer, which speeds infusion and helps it draw flavour, then pour it over to cover everything completely. Any plant matter above the surface can spoil or mould.
Seal with a non-metallic lid, or place a layer of greaseproof paper under a metal one, because vinegar corrodes metal and taints the flavour with a tinny edge over time. Leave it somewhere cool and dark for one to four weeks, tasting as it develops.
Once the flavour is where you want it, strain out the solids through muslin and rebottle the clear vinegar. You can drop in a single fresh sprig as a marker of the flavour, but the bulk of the plant material should come out so it does not over-infuse or cloud.

FAQs
Pack a clean jar with your flavouring, cover it fully with vinegar, and let it steep. I use herbs, fruit, garlic, or chillies, fill the jar, pour vinegar over to submerge everything, seal with a non-metal lid, and leave it somewhere cool and dark for two to four weeks. Shake it every few days. Strain out the solids before bottling, or they'll keep flavouring it and can go off.
Match the vinegar to the flavour, with at least 5% acidity for safety. White wine vinegar is a clean, neutral base that lets delicate herbs shine, cider vinegar suits fruit and warming spices, and white distilled vinegar is sharp and good for pickling-style infusions. Whatever you choose, it needs at least 5% acidity, which the acidity protects the infusion from spoilage.
Vinegar corrodes metal. The acid reacts with metal lids, which can rust, taint the flavour, and leach into the vinegar. I use plastic lids, or put a layer of baking paper between a metal lid and the jar. This matters for the whole steeping period, since it's in contact for weeks.
Several months once strained and bottled, kept cool and dark. The acidity makes vinegar naturally shelf-stable, so a strained, sealed bottle keeps for months. I strain out all solids first, because anything left floating can cloud the vinegar or, in the case of fresh garlic and herbs, raise a small spoilage risk over time. Refrigerate fruit-based ones to be safe.
A small one, and it's worth knowing. Garlic stored in low-acid oil carries a botulism risk, but in vinegar the high acidity makes that far less of a concern, which is exactly why vinegar is the safer medium for garlic infusions. Still, strain the garlic out after steeping rather than leaving it in indefinitely, keep the vinegar at full strength, and refrigerate once opened. Discard anything cloudy or off-smelling.
⚠️ Garlic and fresh herbs are safer in acidic vinegar than in oil, but strain solids out after steeping and refrigerate to avoid any spoilage risk.
