Coffee is one of the most beloved beverages globally, but its journey from plant to cup is deeply tied to the environment in which it is grown. From tropical climates to the influence of local geography, every coffee bean tells a story. Understanding these factors can help us appreciate the diversity of flavors and qualities in every cup.

In this post, we’ll explore the optimal conditions for growing coffee, the significance of the Coffee Belt, and the fascinating concept of terroir, which shapes the flavor profiles of different coffee varieties.


The Ideal Growing Conditions for Coffee

For coffee plants to thrive and produce high-quality beans, they require specific environmental conditions. These factors ensure healthy growth, stable flowering, and the development of complex flavors:

  1. Heat: Coffee plants grow best in warm temperatures, typically between 18°C and 24°C. Extreme heat or cold can harm the plants, making tropical climates ideal.

  2. Humidity: High humidity levels of 60% to 80% are essential for coffee plants to grow robustly.

  3. Rainfall: Coffee plants require consistent rainfall throughout the year, particularly during the growing season. Evenly distributed rain with minimal dry spells is ideal.

  4. Altitude: Elevations between 600 and 2,000 meters above sea level provide stable temperatures and are key to producing high-quality coffee with intricate flavor profiles.

  5. Sunlight: Coffee thrives under filtered sunlight rather than direct exposure. Shade-grown coffee is common, especially in mountainous regions or at higher altitudes.

These conditions are consistently found in a specific global region known as the Coffee Belt.

What is the Coffee Belt?

The Coffee Belt is a global zone located between 23.5° north and 23.5° south of the equator. This region has the perfect mix of tropical climates, consistent warmth, and regular rainfall to support coffee cultivation.

The Coffee Belt includes countries known for their exceptional coffee production, such as:

  • Ethiopia

  • Kenya

  • Colombia

  • Brazil

  • Peru

  • Mexico

  • Panama

  • Vietnam

  • India

  • Hawaii

Each country contributes unique coffee varieties that reflect its local conditions. These regional differences have shaped coffee’s development, influencing flavors, growing methods, and sustainability practices.


How Terroir Shapes Coffee

The term terroir, borrowed from French, refers to the environmental factors that influence how plants grow and develop. For coffee, terroir explains why beans grown in different regions—even from the same variety—taste distinct.


Factors That Define Terroir:

  1. Soil: The composition, nutrient levels, and pH of the soil affect the plant’s growth and the flavor of the beans.

  2. Climate: Temperature, rainfall, humidity, and even the difference between day and night temperatures all play a role.

  3. Altitude: Elevation impacts temperature and humidity, which in turn influence coffee’s flavor complexity.

  4. Geography: Proximity to oceans, mountain ranges, and wind patterns can impact the growing environment.

In simple terms, terroir is the sum of all these factors that give coffee its unique characteristics.

Example of Terroir in Action:

Imagine planting the same coffee variety—like Caturra—in two different countries, such as Kenya and Brazil. While the plants may be genetically identical, the resulting coffee will taste entirely different because of the unique terroir in each location.


The Birthplace of Coffee: Ethiopia

Coffee was first discovered in Ethiopia, widely regarded as the birthplace of coffee. Beans from Ethiopia are often labeled "Heirloom", a term used to describe naturally evolved varieties that have developed over centuries without human intervention.

Ethiopian coffee is celebrated for its diverse flavor profiles, ranging from fruity and floral to rich and chocolatey. When you see "Heirloom" on a bag of Ethiopian coffee, it signifies a rich genetic heritage influenced by the terroir of its specific growing region.


Global Research on Coffee Varieties

While Ethiopia has played a crucial role in coffee’s history, other countries and organizations have contributed significantly to coffee research and development. Some notable organizations include:

  1. World Coffee Research (WCR): Focuses on improving coffee quality and resilience through research on coffee genetics.

  2. International Coffee Organization (ICO): Promotes sustainable coffee practices and innovation worldwide.

  3. Brazilian Agricultural Research Corporation (Embrapa): Specializes in developing coffee varieties resistant to pests and diseases.

  4. Café de Colombia: Supports coffee research and development in Colombia, ensuring the sustainability of local farming practices.

These organizations work with farmers and researchers to develop new coffee varieties suited to changing climates, pests, and market demands.


Coffee Beyond Ethiopia

Although Ethiopia is where coffee originated, its cultivation has spread across the Coffee Belt to countries in Central and South America, Southeast Asia, and beyond. Each region has adapted coffee farming to suit its local conditions, leading to the creation of unique varieties.

For example, the SL28 variety, developed in Kenya, was later grown in Panama as part of a research project by World Coffee Research. This experiment highlights how terroir influences the flavor and characteristics of coffee, making each cup a reflection of its origin.
