Quick Summary

The sugar content in 85% dark chocolate is minimal compared to milk chocolate, though it varies by brand. It's a nutrient-dense option, rich in fiber, antioxidants, and minerals. Higher cacao percentage generally results in lower sugar content.

Key Points

Low Sugar Content: 85% dark chocolate contains significantly less sugar than milk chocolate, with an average of approximately 6.8 grams per 1-ounce serving.
Varies by Brand: The precise sugar amount can differ based on the specific brand's recipe, so always check the nutrition label for the most accurate information.
Rich in Antioxidants and Minerals: Higher cacao content means more beneficial compounds like flavonoids, antioxidants, and minerals such as magnesium and iron.
Less Processed is Better: Choose minimally processed dark chocolate to preserve the maximum amount of beneficial flavanols and avoid less healthy added ingredients.
Key to a Balanced Diet: Enjoying 85% dark chocolate in moderation can be a heart-healthy and brain-boosting addition to your diet due to its low sugar and high nutrient profile.

Cacao Percentage and Sugar Content Explained

When looking at dark chocolate, the cacao percentage is the most important factor in determining its nutritional profile, especially its sugar content. The percentage refers to the total amount of cocoa solids and cocoa butter derived from the cacao bean. As the percentage increases, the amount of added sugar and other ingredients like milk solids typically decreases. For 85% dark chocolate, this means that 85% of the bar is made from the cacao bean, leaving only 15% for other ingredients, primarily sugar and sometimes vanilla or an emulsifier.

Dissecting the Sugar in 85% Dark Chocolate

So, how much sugar does 85% dark chocolate have? While specific values can vary between brands due to different recipes, an average 1-ounce (28g) serving of 70-85% dark chocolate contains approximately 6.8 grams of sugar. Per 100 grams, this can range from around 12 to 15 grams, based on specific product nutrition labels. Some brands may use slightly more or less sugar depending on their desired flavor profile, with some artisanal brands using minimal added sugar. It's crucial to check the nutrition label of your specific chocolate bar to get the most accurate information.

The Impact of Ingredients and Processing

Beyond the primary ingredients, the processing of dark chocolate can also influence its overall nutritional value. Cocoa is rich in potent antioxidants, particularly flavonoids. However, some processing techniques, such as alkalization (also known as 'dutching'), can significantly reduce the flavanol content. Natural cocoa retains more of these beneficial compounds. The ingredients listed on the back of the packaging are the best indicators of a quality product. Look for simple ingredients like 'cocoa mass', 'cocoa butter', and 'sugar', and avoid those with added butterfat or vegetable oils.
