How Much Sugar Is in Dark Chocolate? Sugar by Cacao Percentage

Short answer: according to USDA FoodData Central, dark chocolate with 45–59% cacao contains about 47.9 g of sugars per 100 g, 60–69% about 36.7 g, and 70–85% about 24.0 g (roughly 6.8 g in a 1 oz / 28 g piece). In other words, roughly 24% to 48% of the bar's weight is sugar. The higher the cacao percentage, the less room there is for sugar; for comparison, USDA lists milk chocolate at 51.5 g and unsweetened baking chocolate at 0.91 g per 100 g. For a specific bar, the Nutrition Facts table on its label is the number that counts.

Dark chocolate sugar content by cacao percentage

Sugar drops as the cacao percentage rises: USDA's dark chocolate entries go from 47.9 g of sugars per 100 g at 45–59% cacao to 24.0 g at 70–85%.

Chocolate (USDA entry)	Total sugars per 100 g	Per 1 oz (28.35 g)*	USDA samples (range per 100 g)
Dark, 45–59% cacao solids	47.9 g	13.6 g	5 samples (43.9–51.7 g)
Dark, 60–69% cacao solids	36.7 g	10.4 g	6 samples (35.4–37.9 g)
Dark, 70–85% cacao solids	24.0 g	6.8 g	2 samples (14.5–30.3 g)
Baking chocolate, unsweetened	0.91 g	0.3 g	3 samples (0.56–1.09 g)

*Per-ounce values are calculated by us from USDA's per-100 g figures.

Two things to keep in mind when you read the table. First, USDA groups everything from 70% to 85% in one entry, and its two samples ranged from 14.5 g to 30.3 g of sugars per 100 g, so two bars with similar percentages can differ a lot. Second, these are averages of analysed samples, not the values of any particular brand. The label on the bar, or the technical sheet of the couverture you buy, is always the reference for that product.

To understand what the percentage on the wrapper measures, read our guide to chocolate percentages.

Dark vs milk vs white chocolate

Per 100 g, USDA lists milk chocolate at 51.5 g of sugars and white chocolate at 59.0 g, against 24.0 g for 70–85% dark chocolate.

Chocolate (USDA entry)	Total sugars per 100 g	Per 1 oz (28.35 g)*
White chocolate	59.0 g	16.7 g
Milk chocolate	51.5 g	14.6 g
Dark, 45–59% cacao solids	47.9 g	13.6 g
Dark, 70–85% cacao solids	24.0 g	6.8 g

*Calculated by us from USDA's per-100 g figures. USDA's milk chocolate value comes from 9 samples (50.1–55.1 g); its white chocolate record lists no analysed samples for total sugars.

Note how close a 45–59% dark chocolate sits to milk chocolate: the word "dark" alone says little about sugar. The cacao percentage says much more.

Where the sugar in dark chocolate comes from

Almost all of the sugar in dark chocolate is sugar the maker adds; the cacao bean itself carries very little.

• The bean: the nutrition values on our Ucayali Peru cacao beans list about 1 g of sugars per 100 g (approximate values), and USDA lists unsweetened baking chocolate at 0.91 g per 100 g.
• The type of sugar: in USDA's analyses of dark chocolate, the sugar is sucrose (table sugar). Glucose and fructose were measured at 0 g in all three dark entries; sucrose accounts for 24.0 of the 24.0 g in the 70–85% entry, 36.4 of 36.7 g at 60–69%, and 46.2 of 47.9 g at 45–59% (that entry also shows 1.65 g of lactose).
• The recipe: look at an ingredient list. Bassan's Sur del Lago 71% couverture is declared as 71% total cocoa, made from roasted cocoa beans, cocoa butter, cane sugar and organic sunflower lecithin. FCH's 55% Venezuela dark chocolate minibars list cocoa liquor, cocoa fat, sugar and soy lecithin.

For a producer, this is the key point: the sugar in your chocolate is a decision in your recipe, made through the couverture you choose or, in bean-to-bar, through the sugar you add to your beans.

How much is a lot? Sugar guidelines in context

Health Canada uses a Daily Value of 100 g of total sugars on the Nutrition Facts table, and the WHO recommends keeping free sugars below 10% of total energy intake.

• Health Canada: the % Daily Value for sugars is calculated on 100 g a day for people aged 4 and over. Health Canada's rule of thumb: 5% DV or less is a little, 15% DV or more is a lot.
• World Health Organization (2015): adults and children should reduce free sugars to less than 10% of total energy intake; a further reduction to below 5%, or roughly 25 g (6 teaspoons) a day, would bring additional benefits. Free sugars are the sugars added by the manufacturer, cook or consumer, plus those in honey, syrups and fruit juices.
• American Heart Association: no more than about 100 calories (about 6 teaspoons) of added sugar a day for most American women and 150 calories (about 9 teaspoons) for men.

To put the USDA figures against Health Canada's 100 g Daily Value:

1 oz (28.35 g) of…	Total sugars*	Share of the 100 g Daily Value*
Dark chocolate, 70–85%	6.8 g	about 7%
Dark chocolate, 60–69%	10.4 g	about 10%
Dark chocolate, 45–59%	13.6 g	about 14%
Milk chocolate	14.6 g	about 15%

*Calculated by us from USDA's per-100 g values. The %DV printed on a real label is based on the serving size declared on that product.

For anything about your own diet, including diabetes, ask your doctor or a registered dietitian. Our article on dark chocolate and diabetes covers that question separately.

Reading the sugar on a Canadian label

On a Canadian label, look at "Sugars" in the Nutrition Facts table and at the sugar-based ingredients grouped in the ingredient list.

• Nutrition Facts table: it shows total sugars per serving and their % Daily Value. Compare two chocolates on the same serving size.
• Ingredient list: sugar-based ingredients added to a prepackaged food appear in brackets after the word "Sugars", in descending order by weight, so you can see at a glance that sugars were added and how much they weigh in the recipe.
• Front-of-package symbol: since January 1, 2026, prepackaged foods that meet or exceed set levels of sugars, sodium or saturated fat must carry Health Canada's nutrition symbol. For sugars, the trigger is 15% DV or more for products with a reference amount above 30 g, and 10% DV or more for products with a reference amount of 30 g or less.

If you sell packaged chocolate, check Health Canada's front-of-package labelling guide for your product's reference amount and for the exemptions, such as very small packages under 15 cm² of display surface, and the conditional exemptions for products sold only at farmers' markets or where they are made.

For producers: how you control the sugar in your chocolate

You control sugar by choosing the cacao percentage of your couverture, by working from unsweetened cacao, or by setting your own recipe from the bean.

What you need	Product	Price
A 70%+ couverture for bonbons, tablets and ganache	Bassan Sur del Lago 71%	from $69.95 CAD
70% chips for baking	Organic Dark Chocolate Chips 70%, 1 kg	$45.95 CAD
Cacao with no added sugar for cakes, brownies and sauces	Natural Cocoa Liquor Wafers, 100% Peruvian cocoa	from $29.99 CAD
Beans for your own bean-to-bar recipe	Sur del Lago cocoa beans, Venezuela	from $80.00 CAD
A 55% for breads, croissants and brioches	Venezuelan Blend 55% sticks, 2.27 kg	$62.50 CAD

Choose the cacao percentage of your couverture

Moving a recipe from a 55% to a 70%-plus couverture is the simplest way to reduce sugar, because a higher share of the bar is cacao. Bassan's Sur del Lago 71% is made in Canada from Venezuelan Trinitario cacao with ancestral Criollo lineage, with a working temperature of 30–32°C (86–90°F) and a bilingual technical sheet included. Keep the 55% where sweetness is part of the product, such as the FCH 55% sticks made for breads, croissants and brioches.

Work from unsweetened cacao

Our Natural Cocoa Liquor Wafers are 100% natural cocoa mass from Peruvian fine cocoa, with no added fat or sugar, in easy-melt wafers for cakes, brownies, cookies, sauces and fillings. You decide how much sugar goes in. KKO Real Repostería, the Venezuelan baking cocoa we distribute exclusively in Canada, is a dark alkalized cocoa powder with no sugar added and 10–14% cocoa butter, sold with a bilingual Canadian Nutrition Facts label.

Set your own recipe from the bean

In bean-to-bar, the sugar in the bar is the sugar you put in the refiner. Our Sur del Lago beans come from the southern basin of Lake Maracaibo in western Venezuela, Trinitario cacao with 10–30% ancestral Criollo lineage, fermented to at least 65% uniformity and sun-dried over 7 days, in 1.5 kg, 5 kg, 20 kg and 60 kg formats. For refining, the Bilait R15 takes batches up to about 15 kg, heats up to 70°C (158°F) and holds that temperature in a closed chamber; a conching fan and a glass lid can be requested.
