Overview¶

Coffee production begins with the cultivation of Coffea plants — tropical shrubs or small trees grown within the equatorial Coffee Belt, a band between approximately 25°N and 30°S latitude. The coffee "bean" is the seed of the coffee cherry fruit; two seeds typically develop inside each cherry. Agriculture, agronomy, climate, altitude, soil, and farming practice all directly shape the flavour potential of the harvested crop before it reaches a roaster or consumer.

The Coffee Plant¶

Coffee is produced from species of the Coffea genus in the family Rubiaceae. Two species dominate commercial production:

Species	Common name	Altitude	Caffeine	Share of production
Coffea arabica	Arabica	600–2,200 m	~1.2%	~60–70%
Coffea canephora	Robusta / Canephora	0–800 m	~2.2–2.7%	~30–40%

Arabica is the dominant specialty coffee species; its lower caffeine content, higher complexity, and adaptability to high-altitude conditions make it the target for specialty cultivation. See Arabica and Coffea Genus.

The coffee plant: - Is an evergreen shrub or small tree; in cultivation typically pruned to 2–4 m for harvest access - Produces fragrant white jasmine-scented flowers - Takes 3–4 years to first produce fruit after planting - Bears fruit (coffee cherries) once or twice per year depending on origin and climate - Has a productive lifespan of approximately 20–30 years; some trees survive much longer

The Coffee Cherry and Bean¶

The coffee cherry is the fruit of the Coffea plant. Each cherry contains: - Outer skin (exocarp) — the coloured outer layer; red, yellow, or orange when ripe depending on variety - Pulp / mesocarp — sweet, mucilaginous fruit flesh - Mucilage — a sticky layer adhering to the parchment - Parchment (endocarp) — a papery protective layer around the seeds - Silver skin (spermoderm) — a thin membrane around each bean - Seeds (beans) — typically two flat-faced seeds per cherry; these are the coffee beans

In approximately 5% of cherries, a single round seed develops (called a peaberry or caracol). See Coffee Cherry.

Growing Conditions¶

Coffee quality is strongly shaped by the growing environment:

Altitude¶

Higher altitude slows cherry development, concentrating sugars and producing denser, harder beans with more complex flavour. Most specialty Arabica is grown at 1,200–2,200 m above sea level. See Terroir Factors Altitude.

Climate¶

Coffee requires: - Mean annual temperature of 18–22°C for Arabica (15–24°C range tolerated) - Approximately 1,500–2,000 mm of annual rainfall - Distinct wet and dry seasons (dry season triggers flowering; wet season supports cherry development) - No frost — frost is fatal to coffee plants

See Terroir Factors Climate and Latitude.

Soil¶

Volcanic soils are associated with premium coffee production due to mineral richness and good drainage. Coffee requires: - Well-draining soil; waterlogged roots cause root disease - Slightly acidic pH (5.0–6.5) - Good organic matter content

See Terroir Factors Soil.

Cultivation Practices¶

Shade Growing¶

Traditional coffee cultivation uses shade trees to protect coffee plants from direct sunlight. Shade-grown coffee: - Slows cherry development; increases complexity - Provides habitat for migratory birds (biodiversity benefit) - Reduces need for irrigation and chemical inputs in some systems

Modern intensive sun cultivation produces higher yields but typically at lower flavour complexity.

Harvesting Methods¶

Method	Process	Quality implication
Selective hand-picking	Only ripe cherries harvested; multiple passes	Highest quality; labour-intensive
Strip picking	All cherries stripped from branch in one pass	Mixed ripeness; lower quality
Machine harvesting	Mechanical strip harvesting	Used in flat, large-scale farms (Brazil)

Selective hand-picking is standard in specialty coffee. Uniform cherry ripeness at harvest is critical to cup quality.

Varietals and Cultivars¶

Arabica varieties — including Typica, Bourbon, SL28, Gesha, Caturra, and many others — vary significantly in flavour potential, yield, and disease resistance. The variety planted is a key terroir factor shaping cup character. See Cultivar.

Key Facts¶

Coffee grows within the Coffee Belt (approximately 25°N–30°S latitude); requires tropical climate, no frost, and 1,500–2,000 mm annual rainfall
Two main species: Arabica (specialty dominant; 60–70% of production) and Canephora/Robusta (commodity; 30–40%)
Each coffee cherry contains two seeds (beans); approximately 5% produce a single round peaberry
Coffee plants take 3–4 years to first bear fruit; productive lifespan approximately 20–30 years
Altitude, climate, soil, shade practice, harvesting method, and variety are all key terroir factors shaping cup quality
