From Coffee Tree to Cup: The Full Journey of Coffee

Coffee lovers often wonder: where does their morning cup actually come from? The journey from a seedling in the ground to the rich aroma in your cup involves years of growth, careful harvesting, and precise processing. Understanding this process helps you appreciate the complexity behind every bean.

It takes about three years for a coffee tree to flower and produce fruit. The coffee cherry, which holds the beans, turns red when ripe and is typically harvested between 3–5 years after planting. From there, beans undergo processing, drying, and roasting before brewing.

What Is a Coffee Tree?

Coffee comes from the Coffea plant, a perennial evergreen shrub or small tree in the Rubiaceae family. It’s valued as a high-yield, fast-growing cash crop with broad market demand. In the wild, coffee trees can grow up to 5–10 metres tall. However, on commercial farms, they’re pruned to under 2 metres to boost yields and simplify harvesting.

How Coffee Trees Flower and Fruit

A coffee tree usually flowers for the first time at around three years old. The flowers are small, white, five-petaled, and tubular, with a light jasmine-like fragrance. They grow in dense clusters and typically fall off after two or three days. Several months later, the plant begins to form coffee cherries.

The coffee fruit is a drupe about 1.5 cm in diameter. It starts green, then turns yellow, and finally ripens to a bright red—much like a cherry—hence the name ‘coffee cherry.’ At this stage, the cherries are ready for picking. Each cherry usually contains two coffee beans, which sit facing each other inside the fruit.

Inside the Coffee Cherry

Each coffee bean is covered by a thin membrane called the silverskin (or epidermis), which lies beneath a yellowish layer known as the parchment (endocarp). The beans are encased in a sweet, sticky, pulpy mucilage and surrounded by a soft outer fruit layer. This entire structure makes up the coffee cherry, with the beans as the core.

Harvesting Coffee Cherries

Coffee cherries are picked either by hand or by machine. Mechanical harvesters, widely used in Brazil, are efficient and low-cost but yield uneven ripeness and lower quality. For high-quality beans, hand-picking is preferred—it ensures only uniformly ripe, undamaged cherries are collected, improving the final cup quality.

Processing Methods: From Cherry to Bean

There are two main methods to remove the coffee bean from the cherry: dry (natural) and wet (washed) processing.

Dry Processing (Natural)

In dry processing, cherries are spread out in the sun and allowed to dry naturally. Once fully dried, the outer fruit, pulp, and parchment are removed mechanically. This traditional, low-cost method preserves certain aromatic qualities but can also retain environmental odours. It’s common in parts of Africa and Asia, though some regions now use mechanical dryers.

Wet Processing (Washed)

Wet processing, or the washed method, involves soaking the cherries, then removing the skin and pulp through fermentation and mechanical washing. The beans are left with a layer of parchment (called parchment coffee) and are stored in this state until just before export, when the parchment is removed. This method produces cleaner, higher-quality beans but requires significant water use and investment.

Roasting: Developing Flavour

Roasting transforms green coffee beans into the aromatic, flavourful beans used for brewing. During roasting, starches turn into sugars and acids, moisture and CO₂ evaporate, and proteins break down. The beans expand, develop inner pores, and form a surface oil layer. Roasting develops the bean’s colour, aroma, and taste profile.

This is a technical process requiring precision equipment and skill. It’s generally not practical—or advisable—for home roasting unless done purely for hobby purposes.

Roast Levels Explained

Different roast levels produce distinct flavours:

• Light Roast (Light): Slightly yellow-brown; mild aroma and flavour.
• Cinnamon Roast (Cinnamon): Light brown; slightly stronger aroma, typical of some American-style coffees.
• Medium Roast (Medium): Brown (like chestnut); balanced acidity and aroma, common in classic American roasts.
• High Roast (High): Richer than medium; balanced acidity and bitterness, good flavour complexity.
• City Roast (City): Standard roast level, named after New York City; suitable for Colombian and classic New York-style coffee.
• Full City Roast (Full City): No acidity, stronger bitterness; ideal for iced coffee.
• French Roast (French): Dark roast with oils on the surface; intense bitterness and unique smoky aroma.
• Italian Roast (Italian): Very dark, nearly black; burnt taste, no fragrance, used for espresso.

Frequently Asked Questions

How tall do coffee trees grow in the wild vs on farms?

Wild coffee trees can reach heights of 5 to 10 metres, but those grown on coffee farms are pruned to stay under 2 metres. This controlled height increases fruit yield and makes harvesting easier.

What colour is a ripe coffee cherry?

A ripe coffee cherry turns bright red, similar in appearance to a cherry. This red colour indicates that the coffee beans inside are ready for harvest.

What’s the difference between dry and wet coffee processing?

Dry processing involves sun-drying the whole coffee cherry and then removing the dried husk, pulp, and parchment. Wet processing, or washed processing, removes the skin, pulp, and mucilage with water and fermentation before drying the beans in their parchment.

How long does it take for a coffee tree to produce fruit?

A coffee tree typically flowers for the first time at around three years old, and the cherries are usually ready for harvest between 3 to 5 years after planting.

What are the main coffee roast levels?

Main roast levels include Light, Cinnamon, Medium, High, City, Full City, French, and Italian. Each level varies in colour, flavour profile, acidity, and bitterness—from light and acidic to dark and bitter.

Is coffee roasting something I can do at home?

Home roasting is technically possible but requires specialised equipment and skills. It’s generally not recommended unless done for personal experimentation due to the complexity and risk of uneven roasting.
