Coffee Varieties Explained: Caturra, Geisha and Bourbon
Key takeaways
A variety is a type of coffee plant — like Granny Smith vs Pink Lady, but for coffee.
Almost every variety in the world descends from two ancestors that left Ethiopia: Typica and Bourbon.
Varieties appear three ways: random mutations, deliberate crosses, and lab-bred hybrids built to survive disease.
The list is nowhere near finished — breeders release new varieties every few years, mostly to fight leaf rust and a warming climate.
Questions this article answers
What is a coffee variety?
What are the most common coffee varieties?
Why is Geisha coffee so expensive?
Are new coffee varieties still being developed?
Here's what "Variety: Pink Bourbon" on a bag is not: a marketing flourish, a made-up name, or something you can safely skim past on your way to the tasting notes. It's the actual type of plant your coffee grew on — and it's doing more work than the roast date, the altitude, or half the words printed in bigger type above it.
Here's the good news: varieties are one of the easier bits of coffee nerdery to get your head around, and knowing them genuinely changes what you buy. Not in a "now I can win arguments" way — in a "oh, that's why this bag costs £22" way. Everything on this page maps to real bags you can go and drink, and you can rate any of them on Cuppd afterwards.
Varieties in the wild — Caturra, Ombligón, Castillo, Geisha, Sudan Rume

So what is a variety, actually?
Apples are one species. Granny Smith and Pink Lady are varieties of it — same plant, different fruit, wildly different pie. Coffee works the same way. Nearly all specialty coffee is one species, Coffea arabica, and the variety is which type of arabica plant the beans grew on.
Variety (or cultivar): a specific type of coffee plant within a species. It's the coffee equivalent of a grape variety — Merlot and Cabernet are both grapes, but you'd never confuse the wine.
Each variety brings its own package: how big the tree grows, how much fruit it produces, how well it shrugs off disease, and — the bit you care about — what the cup can taste like. Some varieties are famously delicate and floral. Some are built like a tank and taste like it.
Two plants left Ethiopia and made a mess of things
Arabica evolved in the forests of Ethiopia, and for most of history it stayed there. Then a very small number of seeds made it out — through Yemen, then onto ships — and effectively founded the entire global coffee industry from an alarmingly narrow gene pool.
Two lineages came out of that migration and became the ancestors of almost everything else. Typica travelled east and then to the Americas via Europe's colonial greenhouses. Bourbon took the other route, via the island of Bourbon — now Réunion — in the Indian Ocean. Between them, they're the parents or grandparents of most varieties you'll ever buy.
Which is also the coffee world's biggest structural problem. All those millions of hectares of arabica descend from a handful of plants, so genetically they're basically cousins. Cousins catch the same diseases.
Three ways a new variety shows up
New varieties don't appear at random — well, one of the three ways is literally at random, but bear with us.
- Natural mutation. A plant just… changes. Caturra is a compact mutation of Bourbon that turned up on a Brazilian farm and turned out to be shorter, easier to pick, and higher-yielding. Free upgrade, courtesy of nature.
- Deliberate crossing. Breeders pollinate one variety with another and pick the best offspring. Catuai is Mundo Novo crossed with Caturra — the yield of one, the compact shape of the other.
- Interspecies rescue missions. When leaf rust started wiping out farms, breeders crossed arabica with robusta, which is immune to it, then crossed the result back toward arabica repeatedly until the cup quality came back. Castillo, Catimor, Ruiru 11 and Batian all come from this branch of the family.
Leaf rust (la roya): a fungus that turns coffee leaves orange and kills the tree's ability to feed itself. Outbreaks have wiped out entire regions' harvests, which is why disease resistance drives most modern breeding.
That third group used to have a bad reputation — early rust-resistant varieties cupped like wet cardboard, and the industry hasn't fully let it go. Modern ones are a different story. Plenty of Colombia's best experimental lots are Castillo, and most people can't pick it out of a lineup.
The list is not finished (and never will be)
This is the part most variety guides skip. There is no fixed set of coffee varieties. Breeding programmes at World Coffee Research, CIRAD, Kenya's research institute and national bodies across Latin America are actively releasing new ones — F1 hybrids like Centroamericano and Starmaya, engineered to hold decent cup quality while surviving heat, drought and rust.
There's a reason for the urgency. The land that suits arabica is shrinking as the climate warms, and a crop descended from a handful of plants doesn't have a lot of genetic tricks left. So new varieties keep arriving, and forgotten Ethiopian ones keep getting rediscovered. In ten years this article will need a rewrite. Good.
The five you'll actually see on bags
Across the roasters in the Cuppd catalogue, five names come up more than any others. Here's what each one is, and what's in stock right now from roasters in the US, the UK and mainland Europe.
1. Caturra — the compact workhorse
A natural dwarf mutation of Bourbon, found in Brazil in the 1930s. Shorter trees mean more plants per hectare and no ladders at harvest, which is why it spread across Colombia and Central America and basically never left. In the cup it's clean, sweet and citric — a reliable, bright, well-behaved coffee that lets the farm and the processing do the talking.
Caturra — US, UK, Germany and beyond
2. Geisha — the expensive one
Collected in southwestern Ethiopia in the 1930s, shuffled through research stations for decades, and largely ignored because it produces almost nothing. Then in 2004 a Panamanian farm entered it in a competition, it destroyed the field, and the price of coffee got a new ceiling. Jasmine, bergamot, tropical fruit, tea-like body — when it's grown high and handled properly it doesn't taste like coffee so much as an argument for coffee.
Fun fact
Geisha has repeatedly broken the record for the most expensive coffee ever sold at auction, at prices north of $10,000 per kilo of green coffee. Yes, before roasting. Yes, per kilo.
Geisha — the splurge shelf

3. Bourbon — the elder statesman
One half of the founding duo, named after the island where it spent a century in isolation before spreading to Latin America and East Africa. Low-yielding and a bit fussy, but the cup is why people keep planting it: rounded sweetness, caramel and stone fruit, a body that fills the mouth without shouting. Its offshoots — Yellow Bourbon, Pink Bourbon, Red Bourbon — get their own fan clubs.
Bourbon — sweet, round, classic
4. Catuai — Brazil's backbone
Mundo Novo crossed with Caturra in the 1940s: productive, compact, and stubborn enough to hold onto its cherries in wind and rain. It's everywhere in Brazil and Costa Rica, and it's quietly in a huge share of the espresso you drink without ever being named on the menu. Chocolate, nuts, brown sugar, easy body — the variety that makes milk drinks taste like they're supposed to.
Catuai — chocolate, nuts, easy drinking
5. Typica — the original
The other founding lineage, and the ancestor of Jamaica Blue Mountain, Kona and a long list of others. Typica is a terrible business decision — tall, sprawling, low-yielding, vulnerable to everything — which is exactly why it's been replaced almost everywhere. What's left is worth seeking out: a clean, gentle, sweet cup with elegant acidity and none of the modern varieties' sharp edges.
Typica — where it all started
How much does variety actually matter?
Honest answer: less than the bag implies. Variety sets the ceiling, but altitude, the farm, the processing and the roast decide whether you get anywhere near it. A Geisha that was picked underripe and roasted dark is just an expensive disappointment, and a well-handled Castillo will beat it every single time.
Treat variety as a hint, not a verdict. It tells you what the coffee is capable of, and it tells you what to expect when everything else has gone right. Which is genuinely useful — right up until you meet the bag that ignores the rulebook entirely.
Where to start
Buy two bags of the same origin with different varieties and brew them the same way, back to back. That's the whole lesson in about fifteen minutes, and it sticks better than any article. Then log what you found on Cuppd — the next person deciding between a Caturra and a Pink Bourbon will thank you.
