How Coffee Beans Are Grown - How Optimal Growing Conditions Cultivate Exceptional Flavor

Where a coffee is grown shapes how it tastes long before it ever reaches a roaster. Latitude, altitude, and climate all leave their mark, and understanding them is the fastest way to make sense of why one cup tastes juicy and another tastes heavy and earthy.

FrontStreet Coffee - Introduction to Coffee Bean Growing Regions

Coffee Growing and Production Belt

The Coffee Belt, or coffee production zone, lies between 25 degrees north latitude and 30 degrees south latitude, taking in many countries across Central and West Africa, Southeast Asia, the Pacific, Latin America, and the Caribbean. Coffee is concentrated in this band for one simple reason: temperature. Coffee trees are highly susceptible to frost, so latitudes too far north or south will not work. Only the tropics are suitable, because their heat and humidity are closest to ideal.

In the Coffee World, Altitude Signifies Quality

High Altitude

High-quality Arabica grows at the highest elevations where coffee trees can thrive, anywhere above 450 meters, with 900-1800 meters offering the ideal conditions. In the highlands, special microclimates combine temperature, sunlight, and rain in just the right way to nurture superior beans. Cooler nighttime temperatures also slow the ripening of the cherries, allowing flavor to develop more fully.

Low Altitude

Robusta typically grows in low-altitude regions. Its cherries are larger than Arabica's and ripen faster, but they are less dense. Robusta trees are easier to cultivate and more resistant to disease. Nearly half of all coffee grown worldwide is Robusta because it is simpler to farm, though its flavor quality is often lower.

Coffee Bean Density

How does altitude affect quality? In the highlands, warm days and cool nights slow the growth of the cherries. A longer growing period gives the beans more time to develop rich, complex flavors. The result of growing coffee at elevation is a harder, smaller-looking bean packed with complexity. And the denser the bean, the deeper a roast it can withstand.

Asia/Pacific Region

Coffees from this region often carry earthy aromas and herbal spice notes, with a balanced, heavy body.

Coffee here is mostly processed using the wet-hulled, or semi-washed, method. The area includes the Indonesian archipelago, East Timor, South Asia, and Papua New Guinea. This vast region spans many climates and terrains, and some of the world's most distinctive coffees are found within it. Indonesia alone is a country of thousands of islands and 365 languages, with volcanoes scattered throughout, perfect slope terrain, a mild and steamy climate, and cool mountain nights as charming as its people. Its most famous spot is the resort destination Bali. Given all this, Indonesian beans possess intense aromas and a rich body that make them extremely appealing.

Knowledge Point

Most coffee grows in the equatorial zone between 25 degrees north and south, within the Tropics of Cancer and Capricorn. The growing belt and the country of origin have a tremendous impact on flavor.

In Summary

FrontStreet Coffee is a dedicated coffee research house that enjoys sharing what we know. We hold nothing back, because the more people understand coffee, the more they fall in love with it. That has been our mission for the past six years.

FrontStreet Coffee Recommendation

The best way to feel the effect of altitude is to taste it. FrontStreet Coffee's African single origins grow high and taste bright and vivid. Huakui, a natural-processed Ethiopian heirloom, pours out ripe tropical fruit such as cream strawberry, mango, jackfruit, citrus, and blueberry, while the Yirgacheffe Gotiti Cooperative, washed and graded G1, keeps things clean and precise with white florals, citrus, orange, and green tea.

For a different expression of terroir, FrontStreet Coffee's Jamaica Blue Mountain No. 1 shows what balance looks like when a Typica is grown in the Blue Mountains, and the Panama Red Label Gesha from Hacienda La Esmeralda, grown above 1600 meters, brings the floral, citrus, and peach intensity that high-altitude Gesha is famous for. Tasted side by side, they make the case for altitude better than any chart can.
