Terroir
What is terroir?
The term “terroir” comes up more and more in the world of coffee, much as it has long been used in the world of wine. The reason is simple: terroir has a significant impact on the flavours that show up in the cup. Given how important terroir is, it’s fascinating to pinpoint exactly where a coffee comes from, which lets us directly observe the effect of a specific terroir on a particular bean.
It encompasses all the characteristics that make up the environment in which a coffee grows. That includes altitude, latitude, climate, soil composition, and even the way producers care for their coffee trees. Terroir interacts with the chosen coffee variety to bring out unique characteristics. Even slight variations in terroir will give the coffee different characteristics, translating into distinct results in the cup — even for the same variety grown relatively close by.
Climate
The essential conditions for a coffee tree to grow include a temperate or tropical climate without frost, plenty of sun exposure and enough water. However, excessive sun exposure or too much water can have the opposite, harmful effect on the trees. The ideal is moist, fertile, well-drained soil, under a shaded canopy that still gets a good daily dose of sun.
Soil
Soil considerably influences how a coffee tree grows. Soil types vary from one producing country to another, but soil rich in nutrients and minerals is essential. Coffees grown on volcanic land are common, because these soils are made up of a mix of ash and decomposed rock fragments, creating soil that is rich in nutrients and light enough for optimal drainage.
Altitude
Altitude has a major influence on the flavours that end up in the cup. A higher altitude translates into more complexity and brighter acidity. Conversely, a lower altitude gives a more classic, rounder result.
Traditions
It’s worth considering the traditions of the different coffee-producing countries. For example, the honey process is frequently used in Costa Rica because of efforts made since the 1990s to reduce water consumption. The choice of process, which has a significant impact on a coffee’s profile, is closely tied to the country’s common practices.
Whether it’s the warmth of equatorial regions, the richness of volcanic soils, the effect of altitude on how the cherries ripen, or local traditions, every element of terroir contributes to the complex symphony of coffee flavours. Tasting coffee thus becomes an enriching experience, connecting drinkers to the faraway lands these precious beans come from.
