Heirloom and wild cacao: what the claims mean

Genuinely wild cacao — trees growing without cultivation, harvested from natural populations — exists in the Amazon basin, and the clearest commercial case is the Beni floodplain in Bolivia, where cacao grows in seasonally flooded forest islands and is harvested by boat.

Most bars using the word mean something weaker: feral trees on abandoned plantations, or low-intervention cultivation under forest cover. Those are legitimate things, and calling them wild is a stretch. The word has no regulatory meaning.

Heirloom implies old, genetically distinct, non-commercial populations maintained outside modern breeding programmes. The Heirloom Cacao Preservation initiative in the United States has designated a number of specific lots after genetic and sensory evaluation, which is the closest thing to a verification mechanism the term has.

Outside that, heirloom on a wrapper is a claim without a checker. It may well be true; nothing establishes it.

Ask what would have to be true. Wild harvest means a documented natural population and usually a named collection area. Heirloom means genetic characterisation, which is expensive and which makers who have paid for it will always mention by name.

Where a maker names the population, the region and the testing, the claim is probably real. Where the wrapper says only wild-harvested heirloom cacao, you are reading marketing.
