Coffee Origins
Processing Methods
Ideal Altitude
Flavor Driver
Coffee flavor is determined by three primary factors: origin (where it's grown), altitude (how high), and processing method (how it's prepared). These factors work together to create the unique characteristics you taste in your cup. Understanding them helps you choose coffees that match your preferences and brewing method.
Research shows that terroir—the combination of soil, climate, and geography—significantly impacts coffee flavor. Just like wine, coffee from different regions has distinct characteristics. Ethiopian coffee tastes different from Colombian coffee, which tastes different from Indonesian coffee. These differences are researched extensively and create the diversity in specialty coffee.
✓ Key Flavor Factors:
Coffee grows in the "Bean Belt" between the Tropics of Cancer and Capricorn. Here are the major regions and their flavor profiles.
African coffees are known for bright acidity and fruity, floral notes. Ethiopia, coffee's birthplace, produces beans with complex berry and wine-like characteristics. Kenya offers citrus and blackcurrant notes. These coffees are researched to have the highest acidity levels.
Flavor Profile: Fruity, floral, bright acidity
Best For: Pour-over, light roasts, highlighting origin
Altitude: 1,400-2,200m (highest in the world)
Central American coffees are balanced with medium body and moderate acidity. Colombia produces consistent, high-quality beans with chocolate and nut notes. Costa Rica and Guatemala offer similar profiles with slight variations. These are researched as excellent all-around coffees.
Flavor Profile: Balanced, chocolate, nuts, caramel
Best For: Espresso, all brewing methods, everyday drinking
Altitude: 1,200-1,800m
South American coffees are full-bodied with low acidity. Brazil produces the most coffee globally and offers nutty, chocolatey profiles. Peru provides earthy, spicy notes. These coffees are ideal for espresso and dark roasts.
Flavor Profile: Full-bodied, nutty, earthy, low acidity
Best For: Espresso, dark roasts, milk-based drinks
Altitude: 600-1,200m
Asian coffees are earthy and full-bodied with herbal notes. Indonesia produces unique coffees with low acidity and spicy characteristics. Vietnam is the world's second-largest producer, known for robusta beans. These coffees are researched for their distinctive terroir.
Flavor Profile: Earthy, herbal, full-bodied, low acidity
Best For: Dark roasts, French press, espresso blends
Altitude: 400-1,200m
How coffee is processed after harvesting dramatically affects flavor. There are three main methods, each producing distinct results.
The most common method. Cherries are pulped, fermented in water, then washed and dried. This process removes fruit, creating clean, bright cups. Research shows this method highlights origin characteristics best.
Flavor: Clean, bright, acidic, origin-forward
Process: Pulp → Ferment → Wash → Dry
Time: 12-48 hours fermentation
Best For: Highlighting origin, light roasts, pour-over
Whole cherries are dried in the sun for weeks. The fruit remains on the bean, creating fruity, sweet, full-bodied cups. This method is researched to produce the most unique, complex flavors.
Flavor: Fruity, sweet, full-bodied, complex
Process: Dry whole cherry → Hulk → Sort
Time: 3-4 weeks sun drying
Best For: Espresso, dark roasts, bold flavors
A hybrid method. Cherries are pulped but dried with some mucilage (fruit) remaining. Creates balanced cups with fruit sweetness and clean clarity. This method is increasingly researched and popular.
Flavor: Balanced, sweet, medium body, complex
Process: Pulp → Partial ferment → Dry with mucilage
Time: 1-3 weeks drying
Best For: All brewing methods, balanced flavor
Higher = Better (Generally)
Higher altitude means cooler temperatures, slower cherry ripening, and more complex flavor development. Research shows high-altitude coffees (1,400m+) have higher acidity and more nuanced flavors.
Temperature Effects
Temperature drops about 1°C per 100m of elevation. Cooler temperatures slow ripening, allowing more sugars and acids to develop in the cherry.
Ideal Altitude Ranges
Low altitude (600-1,000m): Full-bodied, low acidity. Medium altitude (1,000-1,500m): Balanced. High altitude (1,500-2,200m): Bright, complex, acidic.
For Bright, Acidic Cups
Choose African origins (Ethiopia, Kenya) with washed processing and light roasts. These combinations highlight acidity and origin characteristics.
For Balanced, Everyday Coffee
Choose Central American origins (Colombia, Costa Rica) with washed or honey processing and medium roasts. These offer consistency and balance.
For Full-Bodied, Bold Cups
Choose South American or Asian origins (Brazil, Indonesia) with natural or honey processing and dark roasts. These create rich, complex flavors.
For Espresso
Choose medium to dark roasts from Central or South America. These have body and sweetness that work well with espresso's pressure extraction.
Understanding origin and processing helps you choose coffees that match your preferences and brewing method. Explore different origins and discover your favorites.
