One of Peru's five main coffee regions. One importer credits it with Peru's largest certified-organic output.
San Martín is among the five regions (with Cajamarca, Junín, Amazonas, Cusco) that together supply about 87% of Peru's coffee. Its Alto Mayo valley (Moyobamba, Rioja and Lamas provinces) counts coffee as its most important socio-economic activity, and one importer says San Martín farmers produce the most certified-organic coffee in Peru.
