The Accidental Farmer

Thomas McOsker

My work explores the distance between what we measure, what we value, and what matters.

I spent fourteen years on Wall Street building financial systems. Then I bought a coffee farm in the mountains of western Puerto Rico. The farm gave me a new set of questions about what markets count, what they leave out, and what happens to the people and places that depend on them. I write about that education as The Accidental Farmer.

Why I Am Writing Here

Somewhere between the coffee trees and the broken machinery, I began taking notes.

What guides the work

What matters should guide what we measure.

The way we assign value should help people take care of it.

At Copper Hill, that means asking what a coffee tree can yield and what it takes to keep the tree and the farm healthy. A second harvest is one way to test how those questions fit together.

Research

My master’s thesis asked whether coffee leaves and fruit could bring growers another source of income. I’m still exploring that question in the field and lab at Copper Hill.

Industry leadership

I’m the founder and CEO of The Whole Tree Company, PBC, which is introducing its first product, Wize. I’m helping establish the Specialty Coffee Leaf Association so growers and buyers have a shared way to describe coffee leaf and evaluate its quality.
