In brief
A coffee variety is a distinct type of plant within a coffee species. Arabica and robusta are species. Typica, Bourbon and Geisha are all varieties within arabica.
Varieties differ in how they grow and how they taste. World Coffee Research says each is "unique in its performance and adaptation to local conditions." Its variety profiles rate traits such as yield, leaf rust resistance and cup quality at high altitude.
On a coffee bag, the variety line tells you which plant the beans came from. You will often see it written as "varietal," a word the coffee trade uses loosely.

What is the difference between variety, varietal and cultivar?
Usage is not settled. KopKopi gives the grammar view: "'variety' is a noun and 'varietal' is an adjective," though "varietal" can work as a noun for the coffee product. Green Coffee Collective notes the trade borrowed "varietal" from wine and simply says it "is what the industry uses."
"Cultivar" is narrower. Olympia Coffee puts it this way: "A variety is a naturally occurring genetic variation within a species while a cultivar is developed by a human to express desirable traits."
Olympia gives examples. Pacas is a natural dwarf mutation of Bourbon, found in El Salvador in 1949. Pacamara is a human-made cross of Pacas and Maragogype, bred by El Salvador's coffee research institute.
Where do the main arabica varieties come from?
Most trace back to Ethiopia through two old lineages, Typica and Bourbon. World Coffee Research says arabica is native to Ethiopia, where its "major genetic diversity" is found.
Seeds moved to Yemen and then India by the late 1600s. In 1706 a single plant traveled from Java to Amsterdam, and its descendants spread Typica across the Americas. Bourbon took a different route: World Coffee Research says French missionaries carried it from Yemen to Bourbon Island, now La Réunion, in the early 1700s.
That narrow start left arabica with little genetic diversity. World Coffee Research notes that in Brazil, 97.55% of cultivars derive from Typica and Bourbon.
Which varieties are well known, and why?
A handful show up on specialty bags again and again. World Coffee Research's catalog profiles 55 arabica and 47 robusta varieties, but home buyers mostly meet a few.
| Variety | Known for | Source detail |
|---|---|---|
| Bourbon | "Excellent cup quality" | Relatively low production; susceptible to leaf rust |
| Geisha (Gesha) | Floral, jasmine, peach-like aromas | Low yield; rose to fame in Panama in 2005 |
| SL28 | Grown in Kenya | Counter Culture cites a Kenyan SL28 at 1,800 m |
| Pacas | Dwarf mutation of Bourbon | Found in El Salvador, 1949 |
Geisha shows how a variety can drive price. World Coffee Research says it was collected from Ethiopian forests in the 1930s. In 2005 the Peterson family of Boquete, Panama, entered it in the Best of Panama auction, where it sold for over $20 a pound.
Does variety really change the taste?
It does, but it is one factor among several. Variety sets the plant's potential. Altitude, farming and processing decide how much of it reaches your cup.
World Coffee Research's Geisha profile makes the point itself: "extremely high cup quality when the plants are managed well at high altitude." The same variety grown poorly will not taste the same. Reading variety together with origin and process gives a better guess than variety alone.
Does a coffee's variety affect grind size?
Indirectly. Variety itself does not set your grind, but it travels with traits that do, such as altitude and bean density.
Counter Culture gives an example with two varieties. A light-roast Catuai grown at 1,650 meters in Honduras will "generally need a coarser grind" than a Kenyan SL28 grown at 1,800 meters. Denser, higher-grown beans resist water and usually need finer grinding.
So treat the variety line as a hint, not a setting. Start from your usual grind for the method, such as BrewMark's pour-over settings, and adjust by taste. If you move between very different coffees often, the grind converter helps you carry settings between grinders.
