Almost everything I say in this shop is about what to pour; this piece is about the one bottle in the house that isn’t destined for a glass at all. Cooking with wine is one of the oldest tricks going — the Roman chef Apicius was already splashing it into his sauces long before anyone thought to write a recipe book — and the plain version is this: it means using wine as an ingredient, for acidity, body and flavour, not as the thing next to your plate (though it’s no crime if the same bottle does both jobs). It works because wine does what vinegar, stock and citrus do, but brings fruit and sometimes oak that none of those quite manage. By the end of this you’ll know which bottle earns a place by the hob, how the classic techniques actually work, and — the bit nobody tells you at the till — exactly what to do with the half-bottle standing on the counter on a Tuesday night.
What is the best way to cook with wine?
There isn’t one best way — there’s a handful of proper techniques, each suited to a different job, and the trick is knowing which one you’re actually doing. Get that right and a £7 bottle earns its keep. Get it wrong and even a decent wine adds nothing but a splash of acid.
| Technique | What it does | Where you’ll use it |
|---|---|---|
| Deglazing | Wine poured into a hot pan lifts every browned bit left after roasting or searing, turning it into the base of a sauce | Pan sauces, a beurre blanc, gravy under a Sunday roast |
| Marinade | The acidity and fruit season and soften meat or fish before heat touches it | Chicken thighs before the grill, oily fish before poaching |
| Stock replacement | Wine stands in for some of the water in a soup, stew or risotto, adding a depth plain stock won’t give | Risotto, French onion soup, a weeknight bolognese |
| Court-bouillon | White wine and water, infused with herbs, used to poach fish or white meat gently | Poached salmon, chicken breast for a salad |
| Reduction | Wine simmered down hard until syrupy, concentrating flavour as the liquid disappears | A red wine jus with steak, a glaze for poached pears |
Cooking with dry white wine works best in the lighter jobs — court-bouillon, deglazing a chicken pan, risotto — where you want acidity without a red wine’s tannin muscling in. On choosing the bottle itself, the trade rule I’ve come to trust after years of getting it backwards is simple: if you wouldn’t drink it, don’t cook with it. Corked wine stays corked once it’s in the pan — that musty, wet-cardboard fault doesn’t cook off, it just gets folded into the dish. Dedicated “cooking wine” off the bottom shelf tends to add nothing at best and something unpleasant at worst. You don’t need to reach for anything special — an everyday bottle around the £8 mark does the job, and if you’re buying one for the hob on purpose, make it a crisp dry white: it covers court-bouillon, deglazing and risotto in a way no red can. Save your good aged bottle for the glass, not the pot (more on why in a moment). If you want the fuller picture of building a kitchen you actually cook and drink from, our pillar guide on drinking well at home covers the rest of that ground.
Turning your leftover half-bottle into tonight’s dinner
Don’t pour it away — that’s really the whole point of this piece. A half-drunk bottle from last night is not a problem, it’s tomorrow’s sauce base sitting there waiting.
The simplest trick going: freeze it. Measure how much wine fills one cube of your ice tray first (pour it in, then tip it into a measuring jug so you know the volume), then freeze the rest in the same tray. Bag the cubes once solid and you’ve got pre-measured wine on standby for any sauce, soup or risotto that calls for a splash — no opening a fresh bottle just to get two tablespoons out of it.
Beyond the freezer, leftover red earns its place properly in:
- Eggs poached in red wine (oeufs en meurette) — simple, and a genuinely good use for a bottle that’s past its drinking best
- Poached fruit — pears or prunes simmered in red wine and a bit of sugar make a fine, simple pudding
- Soups and stews — a splash deepens almost anything you’re already simmering
- Pasta cooked partly in wine — swap some of the pasta water for red wine as it cooks, then finish the sauce with more of the same bottle
If you cook from your leftovers often, let that quietly change what you buy in the first place: a bright, honest mid-week red does double duty in pan and glass in a way a delicate old bottle never will — one more reason the £8 shelf is the most useful one in the shop. If mulled wine is where you land, that’s fine too — just know it’s usually the last resort of a bottle that’s given everything else it had to give. And if what you’re actually after is stopping wine going downhill before it gets to “leftover” status at all, our guide to keeping open bottles alive will save you more bottles than the freezer trick ever will.
What is the 20 minute wine rule?
There isn’t a single number backed by good research, and it took me a while to stop repeating the “20 minutes” line myself before checking it. What’s genuinely true: alcohol boils off at 78°C, well below water’s 100°C, so any wine held above that temperature loses alcohol steadily the longer it cooks — there’s no magic cut-off point where it suddenly vanishes.
What this means in practice is that a sauce simmered gently for five minutes behaves very differently from one reduced hard for forty. The longer you go, the more the wine’s water and alcohol cook away and the more concentrated everything else — the fruit, the acid, the colour — becomes. That’s the actual mechanism behind a good reduction, and it’s worth more than any tidy rule of thumb.
Is dry wine ok for diabetics?
That one belongs with your GP or a dietitian, not your wine merchant — I’m not going to guess at something that matters that much, and I’d rather send you to the right person than offer half an answer. What I can tell you, as a plain fact about the drink rather than a health claim, is what “dry” actually means.
Dry wine is wine where most of the grape’s natural sugar has fermented out into alcohol, leaving little residual sugar behind — that’s the entire definition, nothing more mystical than that. It sits at the opposite end from an off-dry Riesling or a properly sweet Sauternes. In the kitchen, that dryness matters: a dry white won’t sneak unwanted sweetness into a savoury sauce the way an off-dry bottle can catch you out.
Matching what’s in the glass to what’s in the pot
Once you’ve cooked with a wine, the tidiest trick is serving the same bottle alongside the dish — coq au vin is the classic example, made and finished with a red Burgundy or Beaujolais, then poured at the table too. The logic holds elsewhere: a Bordeaux-based sauce sits happily with a red Bordeaux in the glass, and a proper Barolo reduction wants Barolo beside it, not something lighter fighting to keep up. If you’re stocking for this trick rather than chasing one recipe, a Beaujolais-style red and a dry white with a bit of weight will cover the same-bottle-in-pot-and-glass game for most of what a home kitchen cooks.
Poaching asks the opposite of your reduction instinct — go gentle. A tannic, intensely flavoured wine will fight delicate fish or white meat rather than support it; a white Burgundy suits poaching or salt-baking far better than anything with grip. And one habit worth breaking, if you haven’t already: don’t cook with your best aged bottle. Aged wine’s whole appeal is its delicacy, and that’s exactly what gets flattened by garlic, mint, cream or a sharp, sweet-and-sour sauce — the very ingredients most kitchen dishes are built on. Save the old bottle for a quiet night with nothing more than good bread. If you’re after pairing ideas that go beyond the pan, our piece on pairing Italian reds with what you actually cook picks up that thread properly.
Questions customers ask us
Can I use cooking with white wine substitute if I’ve got none in the house? A splash of stock with a spoon of vinegar or lemon juice gets you closer than plain water, mimicking the acidity a dish is usually leaning on. It won’t taste identical, but it won’t sink the dish either.
Does it matter if the wine’s a bit past its best? For cooking, less so than for drinking — a wine that’s tired for sipping can still do good work in a stew or a reduction, provided it isn’t corked or fully vinegary.
Can leftover wine go in a marinade overnight? Yes, and it’s one of the better uses for it — the acidity and fruit work into meat or fish over hours, not minutes, so a slightly flat bottle is no loss here at all.
The merchant’s last word
I’ve poured plenty of wine down the sink over the years before I learned better, and I still wince thinking about it. A half-bottle sitting on the side isn’t a problem to solve — it’s tomorrow’s sauce, or an ice cube tray away from six more meals. Keep something honest and drinkable in for cooking, not the bottle you’re saving, and you’ll never look at leftovers the same way. If you fancy stocking a shelf built for exactly this kind of week, come and browse the Red cellar — I’ll happily point you at the bottles that earn their keep twice.
