If you've ever stood in front of a shelf of coffee bags wondering what "Arabica" actually means or why some bags shout "100% Arabica!" like it's a badge of honour this one's for you.
The Arabica vs Robusta debate is the oldest in coffee. Here's what you actually need to know.
What is Arabica Coffee?
Arabica (Coffea arabica) is the most widely consumed coffee species in the world, making up around 60% of global production. It grows best at high altitudes typically above 1,000 metres in cool, stable climates with plenty of rainfall.
Flavour profile:
- Smooth and nuanced
- Naturally sweet often with fruit, caramel, or chocolate notes
- Bright acidity (can range from gentle to sharp depending on origin)
- Lighter body
Arabica plants are also more delicate. They're vulnerable to disease, harder to grow, and produce less fruit per plant which is part of why Arabica coffee is generally more expensive.
What is Robusta Coffee?
Robusta (Coffea canephora) is the second most produced coffee species globally. It grows at lower altitudes, tolerates heat and humidity, and is far more resistant to disease. As the name suggests, it's robust.
Flavour profile:
- Bold and full-bodied
- Earthy, woody, dark chocolate notes
- Low acidity
- Strong, bitter finish
- Higher caffeine roughly twice that of Arabica
Robusta's reputation has long suffered from being used as cheap filler in mass-market blends. But that's not the full picture.
Why Robusta Gets a Bad Reputation (And Why It's Unfair)
Most of the Robusta you've encountered in supermarket coffee or instant blends was grown at low altitude, harvested cheaply, and processed poorly. Of course it tastes rough.
But Robusta grown at altitude like the coffee in Uganda, where the plant originates is a completely different experience. It develops complexity, a natural sweetness, and a deep, satisfying body that Arabica simply can't match.
Specialty Robusta is one of coffee's best-kept secrets.

Which One Should You Choose?
Choose Arabica if you:
- Prefer a smooth, elegant cup
- Enjoy your coffee black or as a pour over
- Like subtle sweetness and complexity
- Are sensitive to caffeine
Choose Robusta if you:
- Want something bold and powerful
- Drink coffee with milk and need it to cut through
- Love a strong espresso with real body
- Need the caffeine hit to actually count
Choose a blend if you:
- Want the best of both
- Drink coffee in different ways throughout the day
- Haven't yet figured out which you prefer (our Discovery Set is perfect for this)
What Does SOEB Use?
We source both entirely from Uganda.
Our Arabica comes from the highland regions where altitude and volcanic soil create a naturally sweet, smooth cup. Our Robusta is grown at higher altitude than most, giving it the complexity that sets Ugandan Robusta apart.
And our Signature Blend combines the two in a ratio we spent a long time perfecting. It's the everyday coffee smooth enough to drink black, bold enough to stand up to milk.
Not Sure Which to Try First?
Our Discovery Set gives you all three in one order — Arabica, Robusta, and Signature Blend. Brew them side by side, find your favourite, and never overthink your coffee order again.
