Key facts: A coffee variety is the genetic blueprint of the tree — the ceiling on what flavours a lot can ever express. Typica and Bourbon parent most cultivated coffee; Ethiopia and Yemen grow ancient landrace populations; Gesha and SL28 are the flavour celebrities. Peaberry, despite the name, is a bean shape, not a variety.
Walk a cupping table long enough and a pattern emerges: the words on the bag that predict flavour most reliably are not the country, not the farm elevation, not even the roast date. They are the variety names — the genetics that decide whether a coffee can taste of jasmine, or blackcurrant, or dried dates, before a single farming decision is made.
Most roasters in Saudi Arabia buy green coffee fluent in origins but hesitant on varieties. This guide fixes that with the six names that explain ninety percent of what you will ever be offered.
Variety, cultivar, landrace — sorting the words
Three terms get tangled on offer sheets, and untangling them once pays forever.
A variety is a genetically distinct type within the arabica species — the general word. A cultivar is a variety deliberately bred or selected by humans, usually named and propagated on purpose. A landrace is the opposite: a population shaped by centuries of natural and farmer selection in one place, diverse rather than uniform, adapted to its home like a dialect is adapted to a valley.
Why it matters practically: cultivars promise consistency; landraces promise character with variation. Neither is "better" — but you buy them differently, and you should never expect one to behave like the other.
Typica and Bourbon, the old families
Nearly every cultivated coffee variety in the Americas and Asia descends from two siblings that left this region centuries ago.
Typica is the elder: elegant, sweet, clean-cupping, and famously low-yielding — the reason farmers keep abandoning it and cuppers keep mourning it. When you taste an old-school Typica done well, you understand a century of coffee nostalgia in one sip. Ours grows where the family story began: the Haraz Typica natural from Yemen.
Bourbon is the generous sibling — rounder sweetness, caramel and red fruit, slightly better yields. Its mutations and children (Caturra, Catuai, Yellow Bourbon and dozens more) fill Latin American farms, which is why "tastes like good Bourbon" remains the quiet benchmark for balance across an entire hemisphere.
The landraces of Ethiopia and Yemen
Now for the deep gene pools. Ethiopian offer sheets rarely name single varieties; they say "Heirloom" — shorthand for thousands of wild and semi-wild local types growing side by side in the species' birthplace. That genetic chorus is why a Guji or Yirgacheffe can layer bergamot over apricot over florals in a way no single cultivar manages; our Guji natural and Chelchele both sing from that choir.
Yemen answers with landraces of its own — Udaini chief among them — plus the headline discovery of Yemenia, an entire mother population genetically distinct from everything else on earth. That story deserves its own telling, and it has one: our Yemenia deep-dive.
Gesha and SL28, the celebrities
Two names command auction paddles and menu prices.
Gesha (often "Geisha") — an Ethiopian-descended variety made legendary in Panama — delivers the most distinctive profile in coffee: jasmine, bergamot, papaya, a tea-like weightlessness. It is genuinely unlike anything else, which is exactly why unverified "Gesha" on a cheap offer sheet should raise your eyebrow.
SL28 — selected in Kenya in the 1930s — brings the other unforgettable signature: blackcurrant and ripe tomato-sweetness with wine-dark acidity, plus drought hardiness that has farmers replanting it far beyond Kenya. Between them, these two varieties prove the whole thesis of this article: genetics write flavours that processing and roasting can only edit.
Peaberry is not a variety
Time to retire a persistent myth. A normal cherry holds two seeds, flat sides facing. In roughly 5% of cherries, only one seed develops — growing small, dense and round. That is a peaberry: a shape, sorted out by screens, occurring in every variety on every farm.
Why buyers care anyway: the round shape rolls evenly in the drum and the density concentrates flavour, so a well-sorted peaberry lot often cups a touch sweeter and livelier than its flat-bean siblings. Taste the effect in our Yemen Peaberry anaerobic — landrace genetics in their most concentrated packaging.
The names side by side
Name | What it is | Cup signature | Where you'll meet it |
|---|---|---|---|
Typica | Founding cultivar | Elegant, sweet, clean | Yemen, heritage Latin farms |
Bourbon | Founding cultivar | Caramel, red fruit, balanced | Latin America and its offspring |
Ethiopian Heirloom | Landrace population | Florals, citrus, stone fruit, layered | All specialty Ethiopia |
Yemeni landraces / Yemenia | Landrace populations | Dried fruit, spice, winey depth | Yemen only |
Gesha | Star cultivar | Jasmine, bergamot, tea-like | Panama, top-lot programs |
SL28 | Star cultivar | Blackcurrant, winey acidity | Kenya and adopters |
Peaberry | Bean shape (any variety) | Concentrated, lively | Sorted lots everywhere |
What varieties mean for your menu
You do not need celebrity varieties to run a great roastery in Saudi Arabia — you need legible ones. Three moves worth stealing:
Put the variety on the bag. "Ethiopian Heirloom, natural" teaches customers to notice genetics, and customers who notice come back to compare.
Match variety to slot. Bourbon-family lots anchor espresso and milk drinks; heirlooms and landraces shine on filter; a peaberry or Yemeni landrace makes a signature offering with a story your barista can tell in one breath.
Sample by variety, not just origin. Next time you order samples, request two varieties from one origin and cup them side by side — the fastest genetics lesson money doesn't have to buy. Pair this guide with the processing methods explainer and the buyer's guide, and offer sheets stop being a foreign language. Unsure which varieties fit your customers? Ask us in Jeddah — matching them is most of our job.
Frequently asked questions
What are the main types of coffee beans? At species level, arabica and robusta dominate — specialty coffee is overwhelmingly arabica. Within arabica, the main variety groups are the Typica–Bourbon family (most cultivated coffee), the landrace populations of Ethiopia and Yemen, and modern star cultivars like Gesha and SL28.
What is the difference between Typica and Bourbon? Both are founding cultivars of cultivated arabica. Typica cups elegant, sweet and clean but yields poorly; Bourbon offers rounder caramel-and-red-fruit sweetness with slightly better yields, and its mutations populate most Latin American farms.
What does Ethiopian Heirloom mean? It is shorthand for the thousands of wild and locally adapted arabica types growing together in Ethiopia, the species' birthplace. Lots are genetically diverse rather than single-variety, which produces the layered floral-citrus complexity Ethiopia is famous for.
Is peaberry a coffee variety? No — peaberry is a bean shape. When only one seed develops inside a cherry instead of two, it grows small, round and dense. It occurs in every variety, and well-sorted peaberry lots often cup slightly sweeter and more concentrated.
