Every bag on the shelf at a Vancouver roaster tells you a story in shorthand: a country, a farm, a variety, a process, maybe a few tasting notes. Once you can read that shorthand, choosing beans stops being a guess. This guide covers the four coffee species you’ll hear about, the varieties that matter, and how processing and origin shape flavour.
The four coffee species
Coffee comes from the seeds of plants in the genus Coffea. More than a hundred species exist, but only a handful are grown commercially.
Arabica (Coffea arabica)
Roughly 60 percent of the world’s coffee and nearly everything you’ll find at a specialty cafe. Arabica grows best at high altitude in the tropics, where cool nights slow the cherry’s ripening and build more sugar and acidity. Expect sweetness, fruit, florals and a clean finish. The trade-off: it’s a fussy plant, vulnerable to leaf rust and heat, and it carries less caffeine (around 1.2 to 1.5 percent by weight).
Robusta (Coffea canephora)
Most of the rest of world production, led by Vietnam, Brazil and Uganda. As the name suggests, the plant is tougher. It grows at lower altitudes, resists disease and yields more. Robusta has roughly double the caffeine of Arabica, more bitterness, less acidity and flavours that lean to cocoa, nuts and rubber when it’s done poorly. You’ll find it in instant coffee, in many supermarket blends, and in traditional Italian espresso blends, where a little Robusta adds thick crema and punch. Well-grown “fine Robusta” is a small but real specialty category now.
Liberica (Coffea liberica)
A big-leafed, big-cherry species grown mostly in the Philippines (where it’s called kapeng barako), Malaysia and parts of West Africa. The flavour is bold, smoky and sometimes jackfruit-like. Metro Vancouver’s Filipino community means you can occasionally find barako at specialty grocers, and it’s worth trying at least once.
Excelsa
Now classified as a variety of Liberica, Excelsa is grown mainly in Southeast Asia. It’s tart and fruity, and it shows up mostly in blends where it adds complexity.
Arabica varieties you’ll see on labels
Just as wine has Pinot Noir and Cabernet, Arabica has varieties (sometimes called cultivars or varietals) with their own personalities.
- Typica and Bourbon: The two historic lines that most other varieties descend from. Clean, sweet, balanced.
- Caturra and Catuaí: Compact, productive mutations and crosses of Bourbon, common across Latin America.
- Gesha (or Geisha): Originally from Ethiopia, made famous by Panamanian farms. Intensely floral, jasmine and bergamot. Often the priciest bag on the shelf.
- SL28 and SL34: Kenyan selections known for blackcurrant, tomato-like brightness and a juicy body.
- Ethiopian heirloom: A catch-all label for the thousands of wild and landrace varieties in coffee’s birthplace.
- Pacamara: A large-bean cross of Pacas and Maragogype, savoury-sweet and distinctive.
- Catimor and Sarchimor: Hybrids with Robusta heritage that resist leaf rust. Increasingly important as the climate warms.
Processing: the step that changes everything
A coffee cherry has skin, fruit pulp and a sticky layer called mucilage around the seeds. How the farm removes them shapes the taste as much as the variety does.
| Process | How it works | What it tastes like |
|---|---|---|
| Washed (wet) | Fruit removed, beans fermented in water, washed, then dried. | Clean, bright, transparent to origin. Think tea-like Ethiopians and crisp Colombians. |
| Natural (dry) | Whole cherries dried in the sun, then hulled. | Fruity and heavy-bodied: blueberry, strawberry, wine. Can be wild. |
| Honey / pulped natural | Skin removed, some mucilage left on during drying. | Between the two: sweet, round, syrupy. |
| Anaerobic and experimental | Fermented in sealed tanks, sometimes with added yeasts or fruit. | Big, unusual flavours like tropical fruit, cinnamon or boozy notes. Divisive and fun. |
| Wet-hulled (giling basah) | Hulled while still moist, typical in Sumatra. | Earthy, herbal, low acid, heavy body. |
Origins at a glance
- Ethiopia: Floral, citrus, berry. The washed coffees from Yirgacheffe and Guji are the classic “first light roast.”
- Kenya: Juicy, blackcurrant, grapefruit, bold acidity.
- Colombia: Balanced, caramel, red fruit. Huge range by region.
- Brazil: Nutty, chocolatey, low acid. The backbone of many espresso blends.
- Guatemala and Honduras: Chocolate, stone fruit, a gentle brightness.
- Indonesia (Sumatra, Java, Sulawesi): Earthy, spicy, full-bodied.
- Peru, Rwanda, Burundi, Yemen, Panama: All worth chasing for their own reasons, from Rwanda’s red-fruit brightness to Yemen’s ancient, winey depth.
Single origin vs blend
A single origin comes from one country, region, farm or even one lot. It shows off a particular place and season. A blend combines coffees for balance and consistency, which is why most cafes use a blend as their house espresso and rotate single origins on filter. Neither is “better.” A good blend is a skill in its own right.
How to read a bag from a Vancouver roaster
Pick up a bag at any of the region’s specialty roasters and you’ll usually see:
- Origin and producer: Country, region, farm or washing station. More detail usually means more traceability.
- Variety: e.g. Caturra, SL28, heirloom.
- Process: washed, natural, honey, anaerobic.
- Altitude: Higher often means denser beans and brighter acidity.
- Tasting notes: Descriptions of flavours the coffee reminds the roaster of, not added flavourings.
- Roast date: The most useful line on the bag. Filter coffee tastes best roughly 4 to 30 days after roasting, espresso a bit later. If there’s only a “best before,” look elsewhere.
Where to start
If you drink your coffee black, try a washed Ethiopian next to a natural Brazil. The contrast teaches you more in one morning than any article can. If you take milk, start with a Colombian or a chocolatey espresso blend. Then read our guide to coffee roast levels, because roast changes all of the above.
Frequently asked questions
Which coffee bean type has the most caffeine?
Robusta, with roughly twice the caffeine of Arabica.
Is Arabica better than Robusta?
For most specialty drinkers, yes, because Arabica has more sweetness and complexity. But good Robusta has a place, especially in espresso blends.
What does “single origin” mean?
Coffee that comes from one identifiable place, from a country down to a single farm, rather than a blend of several origins.
