Chocolate is often chosen based on its cocoa percentage, but what exactly is it? Chocolate usually consists of cocoa mass, cocoa butter and possibly added sugar (in the case of milk chocolate, milk solids are also added).
The cocoa percentage is the sum of the percentage of cocoa mass and cocoa butter. However, the manufacturer is not required to state the ratios between the two.

For example:
Bar A: with 70% cocoa -> cocoa mass: 62% + cocoa butter: 8%
Bar B: with 70% cocoa -> cocoa mass 50% + cocoa butter 20%

But which one should I buy? Our advice is simple: taste it! Try different bars with the same cocoa percentage, for example two bars of 70% and discover the difference in taste.
