Balsamic vinegar is not high in sodium. A tablespoon of traditional balsamic vinegar contains somewhere between 0 and 5 mg of sodium, making it one of the lowest-sodium condiments available. For context, the FDA threshold for labeling a food “low sodium” is 140 mg per serving, so balsamic vinegar falls far below that cutoff.
How Much Sodium Is in a Serving
A standard one-tablespoon serving of balsamic vinegar delivers roughly 0 to 5 mg of sodium. That’s essentially negligible. The American Heart Association recommends no more than 2,300 mg of sodium per day, with an ideal target of 1,500 mg for most adults. Even if you used several tablespoons of balsamic vinegar in a salad dressing or marinade, you’d still be adding a fraction of a milligram toward that daily limit.
The reason balsamic vinegar is so low in sodium comes down to its ingredients. Traditional balsamic vinegar is made from a single ingredient: grape must, the pressed juice of grapes. That juice is boiled down to a concentrate, then fermented, acidified, and aged in wood barrels for 12 to 25 years or longer. No salt is added at any point in the process.
How It Compares to Other Vinegars
Balsamic vinegar is in line with other vinegars when it comes to sodium. According to USDA data, both apple cider vinegar and distilled white vinegar contain 0 mg of sodium per tablespoon. Vinegar in general is a naturally sodium-free category. If you’re swapping between types of vinegar for flavor reasons, sodium isn’t a factor worth worrying about.
Where balsamic does differ from other vinegars is in calories and sugar. A tablespoon has about 14 calories and 2 grams of sugar, compared to essentially zero for distilled or apple cider vinegar. That’s because of the concentrated grape must. It’s still a small amount, but worth knowing if you’re tracking sugar intake closely.
Watch Out for Balsamic Glazes
Here’s where sodium can sneak in. Balsamic glaze, the thick syrupy reduction often drizzled over caprese salads or roasted vegetables, is a different product from plain balsamic vinegar. A one-ounce serving of balsamic glaze can contain around 192 mg of sodium. That’s nearly 40 times more than a tablespoon of traditional balsamic vinegar, and it crosses the FDA’s 140 mg threshold for “low sodium” labeling.
Glazes often include added ingredients like sugar, thickeners, and sometimes salt or soy sauce to enhance flavor and create that syrupy consistency. If you’re watching your sodium intake, check the label before buying a balsamic glaze or reduction. The bottle might look similar to regular balsamic vinegar on the shelf, but the nutritional profile can be very different.
Cheaper Commercial Bottles Vary Too
Most balsamic vinegar sold in grocery stores isn’t the traditional aged variety. Commercial versions typically blend wine vinegar with grape must and sometimes include caramel coloring or other additives to mimic the flavor of the real thing. These products are still generally low in sodium, but the exact amount depends on the brand and what’s been added. A quick glance at the nutrition label will tell you what you need to know. If sodium is listed at 0 to 10 mg per serving, you’re in safe territory.
Plain balsamic vinegar, whether traditional or commercial, is one of the better choices you can make if you’re trying to add flavor without adding sodium. A splash on roasted vegetables, grilled chicken, or a salad gives you a lot of taste for essentially zero sodium cost, especially compared to soy sauce (around 900 mg per tablespoon) or many bottled salad dressings (150 to 300 mg per serving).
