Terroir — the effect of place — is real in coffee, and it competes with several other variables.
What contributes
Altitude is the strongest single factor. Cooler temperatures slow ripening and produce denser, more complex beans.
Soil. Volcanic soils, common in Central America and Indonesia, are mineral-rich and well drained. Kenya’s distinctive blackcurrant character is often attributed to its soils, though the SL28 varietal contributes too.
Rainfall and its timing. A defined dry season allows even flowering and even ripening. Erratic rain gives mixed maturity on the same branch, which shows up as unevenness in the cup.
Shade. Shade-grown coffee ripens more slowly and is generally denser and more complex.
What can overwhelm it
Processing. A heavy anaerobic natural can taste more of its fermentation than of its origin. This is the honest criticism of some experimental processing.
Roasting. Past second crack, terroir is gone entirely.
Varietal. A Geisha tastes of Geisha nearly everywhere it is grown.
How to taste it
Compare two coffees that differ only in origin — same process, similar roast level, same year. Two washed Bourbons from different countries will show it clearly.
Comparing a washed Colombian with a natural Ethiopian tells you about processing, not place.
