Coffee beans banner showing different roasted coffee beans

Every great cup of coffee starts with the right beans. But with so many varieties, roast levels, and origins to choose from, it can feel overwhelming to know where to start.

There are four main types of coffee beans: Arabica, Robusta, Liberica, and Excelsa. Arabica accounts for about 60-70% of global production and is known for its smooth, complex flavor. Robusta is bolder and higher in caffeine. Liberica and Excelsa are rarer specialty beans with distinctive flavor profiles.

Below, you will find a quick comparison of all four bean types, guides to choosing beans for different brewing methods, and our full library of coffee bean articles.


The 4 Types of Coffee Beans

All coffee comes from one of four main species of the Coffea plant. Each produces beans with a very different flavor, caffeine content, and growing profile.

Bean TypeFlavor ProfileCaffeine% of Global ProductionBest For
ArabicaSmooth, sweet, complex. Notes of fruit, sugar, and berries~1.2%60-70%Pour over, drip, espresso
RobustaBold, earthy, bitter. Notes of dark chocolate and nuts~2.2%25-30%Espresso blends, instant coffee
LibericaSmoky, floral, woody. Unusual and polarizing~1.2%~2%Specialty/single origin
ExcelsaTart, fruity, light body. Often blended for complexity~1.0%<1%Blending, adventurous drinkers

Wondering whether coffee is technically a bean? It is actually the seed of a cherry-like fruit. And if you have seen “espresso beans” on a label, they are not a separate species – espresso beans and coffee beans are the same thing, just roasted differently.


Best Coffee Beans by Brewing Method

Different brewing methods extract flavor differently, so the ideal bean varies depending on how you make your coffee. Here are our top picks:

Coffee Bean Storage and Freshness

Even the best beans will taste flat if they are stored improperly or used too long after roasting. Here is a quick overview of what you need to know:

The grinder you use also plays a big role. A burr grinder produces a more consistent grind than a blade grinder, which makes a noticeable difference in flavor. And yes, you can grind beans in a food processor in a pinch, but it is not ideal.


Coffee Roast Levels: Light, Medium, and Dark Explained

The roast level transforms the same green coffee bean into something entirely different. It is one of the most important decisions when buying coffee, yet most labels give you only a vague description. Here is what each level actually means:

Roast LevelColourFlavour ProfileCaffeineBest For
Light roastLight brown, no oilBright, fruity, acidic, floralSlightly higherPour over, drip, filter
Medium roastMedium brown, minimal oilBalanced, sweet, caramel, chocolate notesModerateEspresso, drip, latte
Medium-dark roastDark brown, some oilRich, bittersweet, less acidityModerateEspresso, Moka pot
Dark roastVery dark, oily surfaceBold, smoky, bitter, low aciditySlightly lowerEspresso blends, cold brew
Coffee roast levels compared by colour, flavour, caffeine, and best brewing method.

One common misconception: dark roasts are not higher in caffeine. Because roasting burns off some caffeine, a light roast actually retains marginally more caffeine by weight. The difference is small, but it is the opposite of what most people expect.

For milk-based drinks like lattes and cappuccinos, a medium roast tends to work best — it holds up to milk without being overwhelmed. For black coffee, a light roast lets the origin characteristics shine. Read our full guide on the best coffee beans for lattes or best beans for cappuccino.
