Quick Answer
One tablespoon (16 g) of balsamic vinegar has about 14 calories, 2.7 g of carbohydrate, 2.4 g of sugar, no fat and almost no sodium. The sugar is naturally occurring, from concentrated grape must, not added. Beyond that the honest summary is short: balsamic vinegar is a low-calorie flavouring, not a source of any nutrient. It contains negligible calcium, iron, potassium and vitamins, and the one health effect with reasonable evidence behind it – a modest blunting of the blood glucose rise after a carbohydrate meal – comes from acetic acid, which every vinegar contains.
Balsamic Vinegar Nutrition Facts

That table is the whole nutritional story, and the part worth internalising is the column of zeros. Balsamic vinegar is often credited with supplying calcium, iron, potassium and manganese, and with supporting bone health. It does not, in any amount that matters. Four milligrams of calcium is 0.3 percent of a day’s requirement.
Why Every Bottle Shows a Different Number
Search for balsamic vinegar calories and you will find figures from 5 to 40 per tablespoon. They are not contradicting each other. “Balsamic vinegar” covers three quite different products, and which one is in your bottle determines everything on the label.
| What it is | What is in it | Effect on the numbers | |
|---|---|---|---|
| Aceto Balsamico Tradizionale DOP (di Modena or di Reggio Emilia) | The protected traditional product, aged a minimum of 12 years, 25 for Extra Vecchio | Cooked grape must and nothing else. No wine vinegar, no colouring, no thickener | Slightly higher sugar and calories per spoon, because years of evaporation concentrate the grape sugars. Used in drops, so intake stays tiny |
| Aceto Balsamico di Modena IGP | The broader protected category. This is what almost everyone actually buys | Cooked grape must blended with wine vinegar. Caramel colour and sulphites are permitted | Lower sugar than DOP because the must is diluted with vinegar. Usually 2 to 4 g carbohydrate per tablespoon |
| Balsamic condiment or glaze | No protected status. Includes most flavoured and infused bottles and all glazes | May contain added sugar, concentrated juice, thickeners and colouring | The widest range and the highest figures. This is where 40 calories a tablespoon comes from |
Two practical markers. Genuine DOP arrives in a numbered, sealed 100 ml bulb-shaped bottle whose shape is legally protected, and costs accordingly. And the ingredient list settles it faster than the front label does: grape must first and a short list means one thing; caramel colour, sugar or glucose syrup means another.
Balsamic Products Compared, All at One Tablespoon
Published figures for these products come at different serving sizes, which makes them impossible to compare as printed. Converted to a common tablespoon:
| Product (1 tbsp) | Calories | Carbs | Sugars | Notes |
|---|---|---|---|---|
| Balsamic vinegar, generic (USDA) | 14 | 2.7 g | 2.4 g | The reference figure |
| Pompeian balsamic vinegar | 5 | 2 g | 2 g | Label figures, rounded as labels permit |
| White balsamic vinegar | 15 | 3 g | 3 g | Made from white grape must, not aged dark |
| Flavoured infused balsamic | ~26 | ~6 g | ~5.8 g | Converted from a 2 tbsp serving |
| Fruit-infused balsamic (raspberry) | 40 | 10 g | 9 g | Nearly three times the generic figure |
| Bottled balsamic vinaigrette | ~43 | ~1.5 g | ~1.2 g | Plus about 4 g fat and roughly 240 mg sodium, from the oil and salt in the dressing |
The spread is roughly eightfold across products all sold as balsamic. The plain vinegars cluster tightly; the infused and glazed ones climb; and a bottled vinaigrette is a different food altogether, because the oil and salt dominate it. That last row is worth noting if you buy dressing rather than making it, since the sodium is the figure that matters there and it does not come from the vinegar.
What the Evidence Actually Supports
One claim about vinegar has a genuine evidence base, and it is worth stating precisely rather than inflating.
Vinegar taken with a carbohydrate meal modestly reduces the blood glucose and insulin rise afterwards. A systematic review and meta-analysis of clinical trials published in Diabetes Research and Clinical Practice concluded that vinegar attenuates postprandial glucose and insulin responses. A 2026 umbrella review of meta-analyses of randomised trials found pooled improvements in fasting glucose, postprandial glucose, HbA1c, total cholesterol, body weight and systolic blood pressure, at doses of roughly 15 to 30 ml a day taken before meals. The proposed mechanisms are slowed gastric emptying and interference with the enzymes that break down starch.
Now the caveats, which matter more than the headline:
- Most of this research used apple cider or white vinegar, not balsamic. The active compound is acetic acid, which balsamic contains, so the effect should broadly transfer – but balsamic has not been the test substance in most trials, and it carries sugar that plain vinegars do not.
- The doses studied are larger than culinary use. Trials typically use 15 to 30 ml, taken deliberately before a meal. A drizzle over salad is a fraction of that.
- The effects are modest and adjunctive. These are pooled averages across small trials, most under 12 weeks. Vinegar is not a treatment for diabetes and does not replace medication or dietary management.
Balsamic also contains polyphenols from grapes, which is a real observation. What does not follow from it is any specific clinical outcome. Polyphenol content is not a health claim on its own.
Claims That Do Not Hold Up
Balsamic vinegar attracts an unusual volume of unsupported claims. For clarity:
- It does not prevent colds or flu. Acetic acid is antimicrobial on a surface in a laboratory. Eating vinegar with a meal does not protect you from respiratory viruses.
- It does not have anti-ageing properties in any demonstrated sense, and nothing about it will make you look younger for longer.
- It does not prevent heart attacks or strokes. Pooled trial data show a small average reduction in total cholesterol and systolic blood pressure. That is not the same as preventing cardiovascular events, and no trial has shown that.
- It is not a source of calcium, iron, potassium or magnesium, and it does not support bone health. See the column of zeros above.
- Boosting pepsin activity is not an established benefit. The idea that vinegar polyphenols increase pepsin, thereby improving protein digestion and raising metabolism, is repeated widely and rests on very little. Balsamic vinegar does not raise your metabolic rate.
- It does not cause weight loss. The umbrella review’s pooled weight difference was around one kilogram across trials, at doses well above culinary use. Using balsamic instead of a creamy dressing saves calories, which is a real and useful thing – but that is arithmetic, not a property of the vinegar.
Risks Worth Knowing
This is the part of the vinegar story with the strongest evidence behind it.
- Dental erosion. Vinegar sits at a pH low enough to dissolve tooth enamel. In an eight-week controlled study, adults taking vinegar daily showed an 18 percent increase in erosive tooth wear scores while the control group showed no change. If you take vinegar deliberately rather than as a seasoning, dilute it, drink it through a straw, rinse with water afterwards, and do not brush immediately.
- Reflux and gastrointestinal irritation. Undiluted vinegar can irritate the throat and oesophagus and worsen reflux.
- Interaction with glucose-lowering medication. Because vinegar can lower blood glucose, taking it regularly alongside insulin or oral diabetes medication carries a hypoglycaemia risk. This needs a conversation with your prescriber, not self-experimentation.
- Kidney disease and potassium-altering medication. Reviews specifically flag caution here.
- Sulphites. Most commercial balsamic contains sulphites, declared on the label, which matters for the small number of people who react to them.
How to Buy and Use It
- Read the ingredient list, not the front label. Grape must and wine vinegar is what you want. Caramel colour, sugar, glucose syrup or thickeners tell you it is a condiment rather than a vinegar. Our guide to reading nutrition labels covers the claims that are legally defined and the ones that are not.
- Treat glaze as a different product. Balsamic glaze is thickened and often sweetened, and can carry several times the sugar of the vinegar it was made from.
- Age claims outside DOP are unregulated. “Aged” on an IGP bottle has a legal meaning of three years; on an unprotected condiment it means whatever the producer wants.
- The swap that actually helps is the dressing one. Balsamic and a little olive oil in place of a bottled creamy dressing genuinely cuts calories and sodium, and the olive oil is the part doing the nutritional work.
Frequently Asked Questions
About 14 calories per tablespoon (16 g) for generic balsamic vinegar, according to USDA data, with 2.7 g of carbohydrate and 2.4 g of naturally occurring sugar, no fat and almost no sodium. Per 100 g that works out to about 88 calories. Flavoured and infused bottles run considerably higher, up to around 40 calories a tablespoon, and balsamic glaze higher still.
Because the name covers three different products. Aceto Balsamico Tradizionale DOP is cooked grape must only, aged at least 12 years, with nothing added. Aceto Balsamico di Modena IGP, which is what most people buy, blends grape must with wine vinegar and may contain caramel colour and sulphites. Balsamic condiments and glazes have no protected status and may contain added sugar and thickeners. Published figures range from about 5 to 40 calories a tablespoon across them, and the ingredient list tells you which you have.
In a true balsamic vinegar, no. The sugar comes from concentrated grape must and is naturally occurring, so it does not count towards the added sugars line on a US nutrition panel. In balsamic condiments and glazes it may well be added, which is why the ingredient list matters. If sugar, glucose syrup or concentrated juice appears there, you are looking at added sugar.
There is reasonable evidence that vinegar taken with a carbohydrate meal modestly blunts the blood glucose and insulin rise afterwards, probably by slowing gastric emptying and interfering with starch-digesting enzymes. A meta-analysis of clinical trials supports this, and a 2026 umbrella review found small pooled improvements in fasting glucose, postprandial glucose and HbA1c at doses of roughly 15 to 30 ml a day. Three caveats: most trials used apple cider or white vinegar rather than balsamic, the doses are larger than a culinary drizzle, and the effects are modest. Vinegar is not a treatment for diabetes and does not replace medication.
No. A tablespoon supplies about 18 mg of potassium, 4 mg of calcium and 0.12 mg of iron, every one of which rounds to zero or one percent of the Daily Value. It contains no vitamin A, vitamin C or fibre. Claims that balsamic vinegar supports bone health through calcium and magnesium, or supplies manganese and iron in useful amounts, are not supported by its composition.
Yes, with regular deliberate use. Vinegar is acidic enough to dissolve tooth enamel, and in an eight-week controlled study adults taking vinegar daily showed an 18 percent rise in erosive tooth wear scores while the control group showed none. Using it as a seasoning on food is a much smaller exposure than drinking it. If you do take vinegar deliberately, dilute it, use a straw, rinse with water afterwards and avoid brushing immediately, since brushing softened enamel makes erosion worse.
At roughly 2.7 g of carbohydrate per tablespoon, all of it sugar with no fibre, balsamic is higher in carbohydrate than plain white, wine or cider vinegar, which are close to zero. A teaspoon or two fits most low-carbohydrate approaches without difficulty; a generous pour is a different matter. Flavoured balsamics and glazes carry considerably more and should be checked against the label rather than assumed.
Glaze is balsamic vinegar reduced and thickened, usually with sugar and often with a thickener added, to make a syrup for drizzling. That concentration means it can carry several times the sugar and calories of the vinegar per spoonful. It is a condiment rather than a vinegar, has no protected designation, and should be read off its own label rather than assumed to match balsamic vinegar figures.
