Dark chocolate explained

Cocoa solids, cocoa butter and sugar with no milk. The type where the beans are audible, and where percentage choice actually changes the experience.

If you read nothing else

Start at 65–70%. It is where most well-made dark chocolate sits, and where origin character is clear without bitterness dominating.

What makes it dark

The absence of milk solids. That single omission is what separates dark from milk chocolate both legally and sensorially — milk proteins bind tannins and coat the palate, so removing them leaves the bean's own character exposed. It is why almost all single-origin and bean-to-bar production is dark.

Choosing a percentage

Below 60% the sugar dominates and origin character is muted. Between 65 and 75% is where most well-made dark chocolate sits and where the beans are clearest. Above 80% the bitterness and astringency become structural rather than incidental, and any fault in the beans is fully exposed. A 100% bar is a different experience rather than a more intense one.

Bitterness and astringency are different

Bitterness is a taste, from theobromine, caffeine and polyphenols. Astringency is a tactile drying sensation from polyphenols binding salivary proteins. Chocolate can be bitter without being astringent. If a bar dries your mouth out, that generally indicates under-fermentation rather than a high percentage.

If you find it harsh

Try a dark milk chocolate at 55–65%, which keeps the cacao level and adds milk to round the acidity. Or try a lower-acid origin — a Ghanaian or Venezuelan bar rather than a Madagascan one. Harshness is often about the specific bar rather than about dark chocolate as a category.
