Arabica vs Robusta: What the Difference Actually Tastes Like

Arabica tastes sweeter and more acidic with more aromatic complexity; robusta tastes heavier, more bitter and distinctly woody or rubbery, and carries roughly twice the caffeine. They are two different species. Arabica is about 60 to 70% of world production and nearly all specialty coffee. Robusta is the rest, and it dominates instant coffee, cheap supermarket blends and traditional Italian espresso, where a little of it is added deliberately for crema and body. The flavor gap comes from chemistry: robusta holds about 2.2 to 2.7% caffeine against arabica's 1.2 to 1.5%, and caffeine is bitter, while arabica carries nearly double the lipids and sugars that produce sweetness and aroma. Robusta also grows at lower elevations, resists disease better and yields more per tree, which is why it costs less. Cheaper is not the same as worse, but in a cup where you can taste the difference, arabica usually wins.

Here is how the two actually differ, and why everything we sell is arabica. Our Colombia is a straightforward example of what arabica is supposed to taste like.

What is the actual difference?

You can often tell them apart by looking. Robusta beans are rounder with a straight line down the middle; arabica beans are longer with an S-shaped crease.

Why does robusta taste harsher?

Three compounds do most of it.

Caffeine is bitter, and robusta has roughly double. Chlorogenic acids, which turn bitter and astringent during roasting, run higher in robusta too. And robusta carries far less of the lipid and sugar content that creates sweetness, aroma and the perception of body in a good arabica.

That combination is why robusta is described as woody, grainy or rubbery. It is not a roasting failure. It is the species.

Is robusta ever the right choice?

Yes, in two places, and it is worth being fair about it.

Traditional Italian espresso blends often include 10 to 20% robusta because it produces thicker, more persistent crema and a heavier body that stands up to milk. Plenty of people prefer that in a cappuccino.

Vietnamese coffee is the other case. Vietnam is the world's largest robusta producer, and the strong, bitter cup served with condensed milk is built around robusta on purpose. Swapping in arabica does not improve it, it just makes something else. We wrote about the regional picture in Southeast Asian coffee compared.

Where robusta is not the right choice is as a silent filler in a bag sold as quality coffee, which is most of where it actually shows up.

What do we use?

Everything we roast is arabica, and that is a flavor decision rather than a marketing one.

We are adding cannabinoids to coffee, and the cup has to survive that. Arabica's sweetness and aromatic range give us something to work with; robusta's bitterness would compete with exactly the qualities we want people to taste. Our Ethiopia Kochere and Mexico Chiapas sit at opposite ends of the arabica range, bright and mellow, and both are recognisably themselves.

Costa Rica makes the point at a national scale: the country banned robusta cultivation for decades to protect its reputation for consistency.

Does the species change the caffeine in a CBD coffee?

It would, which is one more reason we stay with arabica.

A robusta base would roughly double the caffeine per cup, which runs against the point of a calm-energy coffee. Our full-caf arabica sits around 95 mg per 8 oz, the Half-Caf Colombia runs about 50 to 70 mg, and Swiss Water decaf is lower still. Those numbers only hold because the base species is consistent.
