Dark chocolate percentages compared
55, 70, 85 and 100 side by side: what changes, what it costs, and where each is actually useful.
If you read nothing else
70% is the reference point and where fine character reads best. Higher percentages are drier, less forgiving of poor beans, and need recipe adjustment when baked.
The four reference points
At 55% there is substantial sweetness, the chocolate is soft and approachable, and origin character is muted. At 70% sweetness and cocoa are in rough balance and fine character reads most clearly. At 85% the chocolate is intense and drier, with little sugar to round it. At 100% there is no sugar at all, and the result is harsh eaten alone and excellent as a baking ingredient.
The steps are not evenly spaced in experience. The gap between 70% and 85% feels larger than the gap between 55% and 70%.
What changes physically
Sugar contributes structure as well as sweetness, so higher-percentage bars are drier and more crumbly. They also carry more cocoa solid, which absorbs moisture — a fact that matters in baking more than in eating.
And the higher the percentage, the less there is to mask a defect. A poor 85% is considerably worse than a poor 55%.
Where each is useful
55% for eating without concentration and for anyone new to dark chocolate. 70% for tasting, pairing and most baking. 85% when intensity is the point and the maker is trusted. 100% only as an ingredient, where you want to control the sugar yourself.
For baking specifically, adjust the recipe's sugar by roughly the difference whenever you move between bands.
