Last February I watched fresh cacao drip through wooden fermentation boxes outside Chuncho, Peru. Rosa Huaman, the farmer, split a ripe bean with her thumbnail — violet, still warm from the pod. “Seventy-two percent,” she said, holding it to the light. “But you will not see that number on any label you buy.” She was right. That bean would travel two continents and arrive in a bar sold as eighty percent cacao, and nobody in the supply chain between would question the arithmetic.
A Ratio, Not a Grade
Cacao percentage on a label measures the total mass derived from the bean — nibs plus butter, or liquor plus added butter. It reveals nothing about fermentation quality, varietal genetics, or post-harvest drying. A seventy-five percent bar from bulk Forastero in West Africa and a seventy-five percent bar from a rare Nacional hybrid in the Ecuadorian highlands share that number and almost nothing else. We have collapsed an entire origin story into a single, unhelpful digit.
