Biodiversity in San Martín: Why Polyculture Improves Cacao Aroma

San Martín cacao isn't just genetics. It's landscape. The citrus trees (orange, mandarin, lime, Tahiti lemon), banana, papaya and timber trees growing alongside cacao plants aren't accidental — they form an agroforestry system that gives the bean its unique floral and fruity notes.

The secret of flavor: a living terroir

Cacao, like coffee or wine grapes, expresses its environment in its flavor. In San Martín, Fundo Maranatha farmers grow cacao in agroforestry systems where citrus (orange, mandarin, lime, Tahiti lemon), banana, papaya and timber trees like capirona and aguaje grow in the same plot.

This isn't just sustainability — it's flavor engineering. Soil mycorrhizae transfer volatile compounds between roots. Partial shading extends pod maturation, concentrating sugars and aroma precursors. Nearby citrus trees contribute fine acidity and floral notes to the bean.

🍊

Citrus

Citrus + floral notes

Orange and mandarin. Their volatiles reach shared soil and express in the bean.

🍌

Banana

Soft fruity notes

Ideal partial shade for cacao. Decomposing leaves enrich the soil.

🍑

Papaya

Tropical notes

Tropical fruit that coexists with cacao. Its flowers attract insects and its low canopy supports the understory.

🌲

Capirona · Aguaje

Regulated shade

Capirona (native hardwood) and aguaje (palm) form the upper canopy regulating temperature and humidity.

🍋

Lime · Tahiti Lemon

Fine citrus notes

Their aromatic volatiles are shared via mycorrhizae and organic matter, contributing fine acidity to the bean.

Cacao that tastes like its environment — direct from the farm

Our beans, nibs and cacao paste come from agroforestry plots in San Martín. Every cup carries the fingerprint of this unique ecosystem.
