Vinegar (white wine)

Why vinegar (white wine) is rated low

White wine vinegar is low FODMAP at 40mL, and no FODMAP group reaches a meaningful level at that serve. Larger amounts are not rated, so keep to around this serve as your guide. Strip it back and it is acid and water with a wine aroma, and there is almost no fermentable carbohydrate for gut bacteria to feed on. 40mL comfortably covers whisking it into a vinaigrette with olive oil and herbs, deglazing a pan or seasoning rice. Where white wine vinegar tends to cause trouble is by association. It rarely arrives alone. It arrives in a pickle jar, a pan sauce or a pot of brine, and flavoured or sweetened versions bring added ingredients, so the company it keeps is what decides how the meal sits.

What changes your risk

• Serving size 40mL is low and larger amounts are not rated. That covers the splash used to deglaze a pan, sharpen a sauce, dress a salad or season rice. A larger pour is not a realistic way to eat vinegar, so the amount is rarely the deciding factor.
• Pickling brine The vinegar in the jar is not the issue. Pickled onions, pickled garlic and mixed pickles made with an onion and garlic brine are, because the brine takes on what was steeped in it. A jar of plain pickled cucumber or carrot is a different proposition from a jar built around aromatics.
• Pan sauces and reductions Deglazing with white wine vinegar is a genuinely useful move, but only if the pan was not started with onion or garlic. If it was, the sauce carries that flavour for a reason, and reducing it further concentrates whatever was already dissolved in the liquid.
• Flavoured and seasoned bottles Herb infused, fruit infused and seasoned rice style vinegars have added ingredients, and sweetened versions may carry honey or other added sweeteners. Plain is the version this rating describes.
• The rest of the plate Low is a per serving rating rather than a per meal one. Vinegar contributes little to a meal's total, but it also cannot offset the total that other ingredients build up over a sitting.

What else works

Plain white wine vinegar is the keeper here, so the useful comparison is with the bottles people treat as equivalent. Seasoned or sweetened vinegars, shop bought marinades and creamy salad dressings carry extra ingredients that the plain bottle does not, and malt vinegar is a barley product with its own page. Distilled white vinegar behaves as the blunter, harsher cousin in cooking rather than a like for like flavour swap, so choose it for pickling brine and keep the wine vinegar for dressings. To replace the savoury lift that a garlic and vinegar marinade would have given, use white wine vinegar with garlic infused oil, lemon, chives, leek leaves or the green tops of spring onions, and a pinch of asafoetida if you want that deeper background note.

How to keep it low

Look for a bottle whose ingredient list stops at wine vinegar and sulphites, and put back anything labelled seasoned, sweetened or dressing. Once opened, keep it capped in a cupboard rather than beside the hob, since it holds its bright flavour better away from heat. For pickling at home, make your own brine with white wine vinegar, sugar, salt and whole spices so you control what steeps in it, and pack the jars with carrot or cucumber instead of onion or garlic. In the kitchen, a spoonful stirred in at the end of a soup or braise wakes up a dish that would otherwise have needed a sofrito, which is a useful trick when the onion base is off the table.

Common questions

is white wine vinegar ok on a low fodmap diet

Yes. White wine vinegar is low at 40mL, and no FODMAP group reaches a meaningful level at that serve. Larger amounts are not rated.

how much white wine vinegar is low fodmap

40mL is the low serve, so a normal cooking or dressing splash is well covered. Larger amounts are not rated, and in practice the limit is taste.

are pickles made with white wine vinegar low fodmap

It depends entirely on what was pickled and what went into the brine. The vinegar itself is low, but pickled onions, pickled garlic and mixed pickles made with an onion and garlic brine carry what was steeped in them.

can i use white wine vinegar on the elimination phase

Plain white wine vinegar at up to 40mL fits the elimination phase. Seasoned, sweetened or flavoured bottles are not covered by this rating and need checking ingredient by ingredient.
