The Role of Altitude in Coffee Flavour

Ask any specialty coffee professional what single factor most influences coffee quality and many will say altitude. Elevation affects flavour in ways that are both direct and indirect, and understanding it helps explain why some of the world’s most celebrated coffees come from farms perched high in the mountains.

At higher altitudes, temperatures are cooler and the coffee cherry takes longer to ripen — sometimes twice as long as at lower elevations. This slow ripening concentrates sugars and organic acids within the bean, building complexity and the layered flavour profiles that specialty coffee drinkers seek.

High-altitude farming also comes with challenges. Cooler temperatures slow growth, meaning farmers invest more labour per kilogram of coffee produced. These factors are part of why great high-grown coffee commands a premium — and why we are committed to paying prices that reflect the real cost of producing it.
