Chuncho

A native Peruvian population from the Cusco region, grown in the same valleys for centuries and only recently described in genetic terms.

Chuncho is a native cacao population from the La Convención valley in the Cusco region of Peru, at the upper edge of the Amazon basin. It has been cultivated there for a very long time — the region is close to cacao's centre of origin — and it was largely unknown outside Peru until the speciality trade began looking for distinctive material.

The pods and beans are small, yields are low, and the trees are grown in mixed smallholder cultivation rather than plantations. Genetic characterisation of the population is comparatively recent and has generally found it to be distinct from the commercial clones planted elsewhere in Peru.

It is a good example of the broader point that cacao's genetic diversity is concentrated in the upper Amazon and that most of it has never entered commercial cultivation.

What the name actually classifies

Chuncho is a regional population name rather than a clone or a member of the traditional trichotomy, and it covers a genetically varied set of trees rather than a uniform type. It is used loosely in the Peruvian trade and has at times been applied to material from outside the La Convención valley, so provenance matters more than the name does.

What is not known

Genetic characterisation of the population is relatively recent and does not cover the full range of what growers call Chuncho. Flavour descriptions come from a small number of speciality lots, and the small pod and bean size that is often cited as a defining feature is also affected by cultivation conditions rather than being purely genetic.

History

Cultivated in the La Convención valley for centuries and traded locally long before it was described in the international market. Interest from craft makers from the 2000s onwards brought it to wider attention.

Cultivation

Low yielding with small pods and beans, grown in mixed smallholder cultivation at the upper edge of the Amazon basin, frequently alongside coffee.

Flavour

Often described as intensely aromatic with red fruit, floral notes and low bitterness.
