Introduction

Of all the coffee in the world, more than half is Arabica. It is the coffee of speciality cafés, single-origin bags and most of the world’s famous coffee origins, from Ethiopia and Colombia to Kenya and Costa Rica. Arabica is prized for its sweetness, aroma and gentle acidity, and it sets the standard against which other coffees are often judged.

But Arabica is only one of four main types of coffee. The others are Robusta, Liberica and Excelsa, each with its own plant, growing conditions and flavour. Understanding the differences helps you choose the right coffee, whether you brew fresh beans at home or make a quick cup from a premix sachet.

This article is the first of four guides from Desco, the coffee premix brand of Raiden (Pvt) Ltd, marketed by Dsigngo Marketing. It explains where Arabica comes from, how it grows, what it tastes like, how much caffeine it contains, how it compares with the other three types, and its place in Sri Lanka’s coffee story. It also explains how Desco thinks about Arabica when creating its premixes. Coffee Articles 2, 3 and 4 cover Robusta, Liberica and Excelsa.

The four main types of coffee at a glance

Coffee comes from shrubs and trees of the genus Coffea. Scientists have described more than 120 species, but only a few are grown commercially. Almost all the coffee we drink comes from two of them: Coffea arabica (Arabica) and Coffea canephora (Robusta). Liberica and Excelsa make up a small share of world production.

Type	Species	Share of world production	Typical flavour	Main growing regions
Arabica	Coffea arabica	More than half	Sweet, aromatic, fruity or chocolatey, gentle acidity	Latin America, East Africa, parts of Asia
Robusta	Coffea canephora	Around 45%	Strong, bitter, earthy, full-bodied	Vietnam, Brazil, Indonesia, Uganda, India
Liberica	Coffea liberica	Very small (often estimated at under 2%)	Smoky, woody, floral, fruity	Philippines, Malaysia, Indonesia, West Africa
Excelsa	Coffea liberica var. dewevrei (classification debated)	Very small (often estimated at under 1%)	Tart, fruity, complex	Vietnam, Philippines, Southeast Asia

The United States Department of Agriculture forecast world coffee production at a record 178.7 million 60kg bags for 2025/26, of which about 81.7 million bags were Robusta, according to reports of its June 2025 Coffee: World Markets and Trade report. That leaves about 97 million bags of Arabica, or roughly 54% of the total.

Where Arabica comes from

Arabica originated in the highland forests of south-western Ethiopia and the nearby Boma Plateau of South Sudan. Wild Arabica still grows in Ethiopia’s forests, and Ethiopia remains one of the world’s great coffee origins.

From Ethiopia, coffee crossed the Red Sea to Yemen, where it was cultivated by the fifteenth century and traded through the port of Mocha. From Yemen, Arabica spread around the world: to India, to Java in the Dutch East Indies, to the Caribbean and to Latin America, which is now the world’s largest coffee-growing region.

Arabica in Ceylon

Arabica also made Ceylon, today’s Sri Lanka, one of the world’s largest coffee producers in the nineteenth century. Plantations spread across the hill country, and by about 1870 Ceylon was among the world’s leading exporters. Then coffee leaf rust, a fungus called Hemileia vastatrix, arrived around 1869 and spread rapidly. Coffee exports collapsed, and by about 1890 most coffee land had been abandoned. Planters turned to tea, and Ceylon became a tea island.

Coffee never disappeared from Sri Lanka, though. Today, the island grows small amounts of Arabica in the hills and Robusta at lower elevations. According to the Department of Export Agriculture, production rose from 2,439 tonnes in 2021 to 2,537 tonnes in 2022, mostly consumed at home. Interest in Sri Lankan speciality Arabica is growing, and new estates are planting coffee again.

How Arabica grows

Arabica is a demanding plant. It grows best in specific conditions:

Altitude: usually about 1,000 to 2,000 metres above sea level in the tropics, and sometimes higher. Some famous coffees grow above 2,000 metres.
Temperature: cool and mild, ideally about 15–24°C. Arabica suffers in heat and is damaged by frost.
Rainfall: well-distributed rain, with a dry season that triggers flowering.
Soil: rich, well-drained soil, often volcanic.
Shade: many farms grow Arabica under shade trees, which slows ripening and protects the soil.

A self-pollinating plant

Unlike Robusta, Arabica is self-pollinating: each flower can fertilise itself. This makes Arabica genetically quite uniform and stable, so farmers can grow a named variety and expect consistent results. But it also means Arabica has limited genetic diversity, which makes it more vulnerable to diseases such as leaf rust and to climate change.

Arabica is also tetraploid, meaning it has four sets of chromosomes (44 in total). Scientists believe it formed naturally from a cross between Coffea canephora (Robusta) and Coffea eugenioides, a wild species, long ago in Ethiopia.

Famous Arabica varieties

Within Arabica there are many varieties and cultivars, each with its own flavour and growing traits. Some of the best known are:

Typica and Bourbon: the two historic varieties from which many others descend. They are known for sweetness and clarity, but have lower yields.
Caturra and Catuaí: compact plants with higher yields, widely planted in Latin America.
Geisha (Gesha): originally from Ethiopia, famous for intense floral and tea-like flavours and record auction prices.
SL28 and SL34: developed in Kenya, known for bright, blackcurrant-like acidity.
Catimor and Sarchimor types: crosses with the Timor Hybrid, which carries Robusta genes for rust resistance.

Inside the coffee cherry

Coffee beans are the seeds of a fruit called the coffee cherry. Each cherry usually contains two seeds, which face each other with their flat sides together. Before the beans can be roasted, the layers around them must be removed.

Pulp (mesocarp)
Mucilage
Parchment (endocarp)
Silver skin
Bean (seed), usually two per cherry

Figure 2: Inside a coffee cherry: the layers around the two coffee beans.

Skin (exocarp): the outer red or yellow skin of the ripe cherry.
Pulp (mesocarp): a thin layer of sweet fruit flesh.
Mucilage: a sticky, sugary layer around the parchment.
Parchment (endocarp): a thin, papery husk that protects each bean.
Silver skin: a delicate membrane on the bean itself, which mostly comes off as chaff during roasting.
Bean (seed): the green coffee bean, which is roasted.

Sometimes a cherry contains only one round seed instead of two flat ones. This is called a peaberry, and some roasters sell peaberries separately.

How these layers are removed, by washing, drying the whole cherry, or a mix of both, has a big effect on flavour. Liberica Coffee: The Rare, Bold Bean With a Ceylon Connection explains the main processing methods.

What Arabica tastes like

Arabica beans contain more sugars and lipids (oils) than Robusta beans, and less caffeine and fewer chlorogenic acids. These differences are why Arabica usually tastes:

Sweeter, with notes of caramel, chocolate, honey or fruit.
More aromatic, with floral, citrus, berry or nutty aromas.
Brighter, with a pleasant acidity that tasters compare to the brightness of fruit.
Smoother and less bitter than Robusta.

The origin, variety, altitude, processing and roast all shape the flavour. A washed Ethiopian Arabica might taste of jasmine and lemon; a natural Brazilian Arabica, of chocolate and nuts; a Colombian Arabica, of caramel and red fruit.

Arabica and roasting

Light roasts keep more of Arabica’s fruity, floral character and acidity. Medium roasts balance sweetness and acidity. Dark roasts bring out bittersweet, chocolatey and smoky notes, but can hide origin character. Many speciality cafés roast Arabica light to medium; many espresso blends and instant coffees use darker roasts.

How much caffeine is in Arabica?

Arabica beans usually contain about 1.2–1.5% caffeine by dry weight, roughly half the caffeine of Robusta beans, which contain about 2.2–2.7%. Robusta Coffee: The Strong Bean Behind Instant Coffee and Premixes includes a chart comparing the two.

In the cup, caffeine depends on how much coffee you use and how you brew it, not just on the bean. A large mug of filter coffee made with Arabica can contain more caffeine than a small espresso made with Robusta. As a rule, though, Arabica gives a gentler cup with less caffeine for the same weight of coffee.

How Arabica is graded and sold

Arabica is bought and sold as green coffee, and buyers use several systems to describe its quality.

Screen size: beans are sorted through sieves with round holes, measured in 64ths of an inch. Larger beans (for example screen 17/18) often fetch higher prices, although size alone does not guarantee flavour.
Defects: buyers count defects such as black, sour, broken or insect-damaged beans in a sample. Fewer defects mean a higher grade.
Country grades: many origins use their own names. Kenya grades beans as AA, AB and so on by size; Colombia uses Supremo and Excelso; some Central American countries grade by altitude, with “Strictly Hard Bean” for high-grown coffee.
Cup score: speciality buyers taste coffee using a standard cupping method and score it out of 100. Coffee scoring 80 points or more is usually described as “speciality coffee”.

Most Arabica is traded against the “C” price on the New York futures market, with a premium or discount for origin and quality. Speciality lots are often sold directly, at prices well above the market.

Arabica and climate change

Arabica’s preference for cool, stable conditions makes it vulnerable to climate change. Research has warned that the area suitable for Arabica could shrink significantly in the coming decades as temperatures rise, and that diseases and pests may spread to higher altitudes. Farmers are responding by planting at higher elevations, using shade trees, adopting rust-resistant varieties, and, in some regions, switching to Robusta or Liberica.

This is one reason scientists and roasters are paying new attention to the “other” coffee species. Liberica and Excelsa, covered in Coffee Articles 3 and 4, tolerate heat better than Arabica, and they may play a bigger role in the future of coffee.

Arabica in instant coffee and premixes

Instant coffee is made by brewing roasted coffee at industrial scale and then drying the coffee extract into powder or granules. Most of the world’s instant coffee is made mainly from Robusta, because it is more affordable, gives a strong flavour and has a high yield of soluble solids. Premium instant coffees, however, often use Arabica, or a blend of Arabica and Robusta, for a smoother, more aromatic taste.

When Desco develops a premix, the coffee blend matters as much as the creamer and sugar. A higher share of Arabica gives a smoother, sweeter, more aromatic cup, which suits cappuccino and latte-style premixes. A higher share of Robusta gives strength and a bold kick that stands up to milk and sugar, which suits classic 3-in-1 and strong premixes. Desco premixes are made with coffee from our own plantations in Sri Lanka, where Arabica grows in the hills and Robusta at lower elevations.

Robusta Coffee: The Strong Bean Behind Instant Coffee and Premixes explains how a coffee premix is made, from roasting to sachet.

How to enjoy Arabica coffee at home

If you buy Arabica beans or ground coffee, a few simple habits help you get the best from them:

Buy fresh. Coffee is best within a few weeks of roasting. Look for a roast date on the bag.
Grind just before brewing, if you can. Ground coffee loses aroma quickly.
Use the right ratio. A good starting point is about 60 grams of coffee per litre of water (about 15 grams for a 250ml mug).
Use hot, not boiling, water. About 90–96°C extracts flavour without scorching the coffee.
Store beans airtight, away from light, heat and moisture. Do not keep them in the fridge, where they absorb smells.

For a quick cup at work or on the move, a good premix gives a consistent coffee with milk and sugar in seconds, without any equipment.

How Desco brings coffee to everyday life

Desco is built on the same simple structure as its sister tea brand, Hakgala:

Raiden (Pvt) Ltd owns the Desco brand and is responsible for product standards, sourcing and supply. Raiden is the parent company of Dsigngo Group, based in Kelaniya, Sri Lanka.
Dsigngo Marketing manages the brand: Desco’s identity, sachet and pack design, product photography, the website and online shop, social media and trade marketing to retailers, offices, hotels and distributors.
Raiden’s own plantations supply the coffee, and the premixes are produced and packed in Sri Lanka under local and international certifications.

The Desco range includes classic hot premixes, Ceylon spiced coffees and iced premixes, in single sachets, family packs and catering packs. See the Desco premix menu on the World of Coffee page.

An example in practice

The following example is illustrative and does not describe a real client.

An IT company in Colombo with 150 staff wants better coffee in its pantries. Staff complain that the current coffee is either too bitter or too weak, and the company does not want the cost and cleaning of espresso machines.

Dsigngo Marketing arranges a tasting of three Desco premixes: a classic 3-in-1, a smoother cappuccino-style premix and an unsweetened black coffee for staff who prefer no sugar. Staff vote, and the company chooses a mix of all three in catering packs, with a monthly delivery from Raiden. Dsigngo designs a pantry poster that explains the four coffee types, so staff learn why the cappuccino tastes smoother and the classic tastes bolder.

The result is a coffee service that suits different tastes, with no machines to maintain.

Frequently asked questions

Is Arabica better than Robusta?

Not always. Arabica is usually sweeter and more aromatic, while Robusta is stronger and more bitter, with more caffeine. Many of the best espresso blends and premixes use both.

Does Sri Lanka grow Arabica coffee?

Yes. Sri Lanka grows Arabica in the hill country and Robusta at lower elevations. Production is small, about 2,500 tonnes a year according to the Department of Export Agriculture, but interest in speciality Sri Lankan coffee is growing.

Why is Arabica more expensive?

Arabica grows at high altitudes, yields less, is more vulnerable to disease and climate, and is in high demand for speciality coffee. All of this raises its price compared with Robusta.

How much caffeine is in Arabica?

Arabica beans contain about 1.2–1.5% caffeine by dry weight, about half as much as Robusta. The caffeine in your cup depends on how much coffee you use and how you brew it.

What does "100% Arabica" mean?

It means the coffee contains only Arabica beans, with no Robusta or other species. It says nothing about the origin, freshness or roast, so check those too.

Does Desco use Arabica coffee?

Desco uses coffee from our own plantations in Sri Lanka, which grow Arabica in the hills and Robusta at lower elevations. Contact Dsigngo Marketing for product specifications.

Conclusion

Arabica is the world’s most popular coffee for good reason. Born in the forests of Ethiopia, it once made Ceylon one of the world’s coffee giants, and today it accounts for more than half of global production. It needs cool, high slopes and careful farming, and it rewards that care with sweetness, aroma and gentle acidity. But it is only one of four coffee types, and Robusta, Liberica and Excelsa each bring something different.

Desco, the coffee premix brand of Raiden (Pvt) Ltd, marketed by Dsigngo Marketing, brings these coffees into everyday life, from a classic 3-in-1 at home to spiced and iced coffees for offices, hotels and shops.
