What does the percentage on chocolate mean?
The combined mass of everything that came from the bean — cocoa solids plus cocoa butter — as a share of the bar. It is a statement about proportion, not about quality.
If you read nothing else
The percentage tells you how much of the bar is not sugar. It does not tell you how that cacao mass splits between solids and butter, which is much of what determines whether a bar tastes rich or harsh.
What the number counts
A 70% bar is 70% cacao-derived mass by weight: cocoa solids and cocoa butter added together. The remaining 30% is almost entirely sugar, plus small quantities of lecithin and vanilla. On milk chocolate the remainder includes milk solids as well as sugar, so a 40% milk bar contains less sugar than the figure alone suggests.
What it does not tell you
It does not say how the cacao mass divides between solids and butter, and two 70% bars can differ by ten percentage points of cocoa butter. Cocoa solids carry flavour and bitterness; cocoa butter carries texture and mildness. A maker chasing a silky melt adds cocoa butter, which raises the percentage while making the bar taste milder — the opposite of what the number implies.
White chocolate is a different measurement
White chocolate contains no cocoa solids at all, so its percentage refers to cocoa butter alone. A 35% white chocolate is roughly a third cocoa butter, which is a statement about richness. Comparing it with a 35% milk bar is comparing two different things.
Higher is not better
A higher percentage means less sugar and more cacao. Whether that is better depends entirely on the beans and the processing. Poorly fermented beans at 85% are simply more of a bad thing, and plenty of excellent chocolate sits at 65%. The number is a preference guide, not a quality ranking.
