Apple Cider Vinegar Labels: Raw, Unfiltered, the Mother and Acidity
A bottle of apple cider vinegar has more words on it than you might expect: raw, unfiltered, unpasteurized, “with the Mother”, a percent acidity and a Nutrition Facts panel full of zeros. Some of those words come from FDA policy and some are the brand’s own. This guide walks through each part of the label and says which is which. Our worked example is the one vinegar we carry, Bragg Organic Raw Apple Cider Vinegar. For the basics of any food panel, see our guide on how to read a Nutrition Facts label.
How we wrote this: the label details come from the Bragg 32 fl oz (946 mL) bottle as photographed on Open Food Facts, product 0074305001321 (user submitted photos; the current front and side photos are dated September 2025, viewed in October 2026). The rules come from FDA Compliance Policy Guide Sec. 525.825 on vinegar, and from the FDA labeling regulations at 21 CFR 101.12 and 21 CFR 101.9. We describe what the label and the rules say. We have not tested this product, the label on your bottle may differ, and this is not diet or medical advice.
Step 1: What “apple cider vinegar” means
There is no formal standard of identity for vinegar. Instead, FDA Compliance Policy Guide Sec. 525.825, issued in 1977 and revised in 1995, sets out how FDA expects vinegar to be labeled, and FDA says it remains current policy. It defines “vinegar, cider vinegar, apple vinegar” as the product made by the alcoholic and then acetous fermentation of the juice of apples. In other words, apple juice is first fermented to alcohol, and then the alcohol is fermented to acetic acid.
The name is about the juice. The same FDA guide says vinegar made from dried apples, apple cores or apple peels should be labeled “vinegar made from ___” instead. It cites a 1924 Supreme Court case, U.S. v. 95 Barrels … Alleged Apple Cider Vinegar, in which the Court held that vinegar made from dried apples could not simply be called “Apple Cider Vinegar”. So when a label says apple cider vinegar, the policy expects it to start from apple juice.
Step 2: The acidity line
Strength is the one number that really sets vinegars apart. According to CPG 525.825, natural vinegars normally contain more than 4 grams of acetic acid per 100 mL, and each listed variety, cider vinegar included, should contain 4 grams per 100 mL. If water is added, the label must say so, with a statement such as “diluted with water to ___ percent acid strength”, and in no case should the strength be less than 4 percent.
The Bragg label photographed on Open Food Facts says “DILUTED TO 5% ACIDITY.” next to the Nutrition Facts panel. By our comparison, that is above the 4 percent floor in the FDA guide. The label gives the strength as a percent only; it does not name the acid. By our calculation, reading 5% as about 5 g of acetic acid per 100 mL (the unit the FDA guide uses), one tablespoon (15 mL) holds roughly 0.75 g.
Why is it diluted? The current ingredients line on the photographed label reads “ORGANIC APPLE CIDER VINEGAR, WATER.” An earlier version of the label, photographed in 2021, read “Certified Organic, Raw Apple Cider Vinegar and Purified Water. Diluted to 5% acidity.” Either way, the water is there to set the strength printed on the bottle.
Step 3: Raw, unfiltered, unpasteurized and the Mother
The front of the Bragg bottle, as shown on Open Food Facts, says “ORGANIC”, “RAW~UNFILTERED”, “APPLE CIDER VINEGAR”, “WITH THE ‘MOTHER'” and “UNPASTEURIZED”. By our reading of CPG 525.825, the FDA guide does not define raw, unfiltered, unpasteurized or Mother. Treat them as the brand’s own description of how the vinegar is made, not as terms with an FDA definition behind them.
What is the Mother? Bragg has described the Mother on an older label, photographed in 2021 and shown on Open Food Facts, as “molecules of organic acids and enzymes connected in strand-like chains.” We did not see that wording on the current wrap, and the label does not tie the Mother to any particular result, so neither do we. The current side panel on the photographed label also says “AS A NATURAL PRODUCT, COLOR & FLAVOR MAY VARY.”, so one bottle can look a little different from the next.
Step 4: The Nutrition Facts panel
The photographed Bragg label carries a Nutrition Facts panel, which means it is sold as a food, a condiment. Compare a dietary supplement such as collagen peptides, which carries a Supplement Facts panel instead; our collagen peptides label guide shows that kind. Here is what the Bragg panel lists:
- Serving size: 1 tbsp (15mL), with 63 servings per container. 21 CFR 101.12 sets the reference amount for major condiments, vinegar included, at 1 tbsp, with the label statement “1 tbsp (15 mL)”. By our calculation, 946 mL divided by 15 mL is about 63.
- Calories 0. Under 21 CFR 101.9(c)(1), calories are declared in 5 calorie steps up to 50, and amounts under 5 calories may be shown as zero. So “0” means less than 5 per serving, not necessarily none at all.
- Total fat 0g, sodium 0mg, total carbohydrate 0g, protein 0g, each with 0% Daily Value where a %DV applies.
- The footnote: “Not a significant source of saturated fat, trans fat, cholesterol, dietary fiber, total sugars, added sugars, vitamin D, calcium, iron and potassium.”
That short layout has a name. 21 CFR 101.9(f) allows a simplified format when a food has insignificant amounts of eight or more of the listed nutrients. The panel must still show calories, total fat, total carbohydrate, protein and sodium, and it adds a “Not a significant source of ___” line for the rest, which is exactly what the Bragg panel does.
Step 5: Organic and other marks
The front of the photographed bottle shows the USDA Organic seal and the Non-GMO Project Verified mark, and the side panel says “Certified Organic by Organic Certifiers”, “PRODUCT OF USA” and “DISTRIBUTED BY: BRAGG LIVE FOOD PRODUCTS, LLC SANTA BARBARA, CA”, along with a Certified B Corporation mark. In the USDA Organic Integrity Database, Bragg Live Food Products, LLC is listed as Certified by Organic Certifiers, Inc., with apple cider vinegar on its handling list.

A quick label check
- Name: “apple cider vinegar” should mean vinegar from apple juice, not from dried apples, cores or peels.
- Acidity: look for the percent; FDA policy expects at least 4 percent, and a “diluted” statement if water was added.
- Raw, unfiltered, Mother: these are the brand’s words, not FDA defined terms.
- Panel: Nutrition Facts, 1 tbsp serving, and zeros that follow the FDA rounding rules.
- Marks: check any organic claim against the USDA Organic Integrity Database.
FAQ
Does “Calories 0” mean apple cider vinegar has no calories?
Not exactly. 21 CFR 101.9(c)(1) lets a label show less than 5 calories per serving as zero.
Is 5% acidity strong or weak?
It is above the 4 percent minimum in FDA CPG 525.825. The Bragg label says it is diluted to that strength.
Does the FDA define “raw” or “the Mother” for vinegar?
By our reading of CPG 525.825, no. Those words are the brand’s label terms.
Is the label the same on every bottle size?
We looked at the 32 fl oz bottle only. Servings per container will differ on other sizes, and labels change over time, as the older Bragg wording shows.
