A Century of Volcanic Soil: The Sierra de Chinameca in the 1916 Libro Azul

More than a century ago, the volcanic landscape of eastern El Salvador was already being documented for its agricultural richness.

The Libro Azul de El Salvador, published in 1916 by the Latin American Publicity Bureau Inc., describes the region around San Miguel and Chinameca as land shaped by volcanic activity, decomposed rock, minerals, and organic matter — conditions considered highly favorable for agriculture.

One passage specifically notes that in the district of Chinameca there was lava transformed into soil, together with sulfur, clay, iron oxides, and pyrites. It also describes the Sierra de Chinameca as an area rich in granite, trachytes, soft sandstone, calcareous clays, sulfur, and pyrites.

For us at Finca San Francisco, this historical description is especially meaningful and full of commitment of protection.

Our coffee grows in the Sierra Tecapa-Chinameca, a landscape shaped by volcanic history and generations of agricultural life. Long before Café San Francisco existed as a brand, this land was already recognized for the characteristics that made it suitable for cultivation.

Today, more than 100 years after the Libro Azul was published, we continue to care for coffee trees on this same volcanic landscape.

We do not claim that any single mineral determines the flavor of our coffee. Coffee quality is influenced by many factors, including variety, altitude, shade, climate, farming practices, processing, and roasting. But the historical record gives us something equally valuable: a glimpse into how this region was understood more than a century ago.

For our family, coffee is not only a crop. It is part of a place, a landscape, and a history that continues from one generation to the next. My great grandfather, my grandfather and then my mom owned this land before passing it to me, for that I am grateful.

From the Sierra Tecapa-Chinameca to your cup.
