Yemen’s coffee tastes the way it does because of what it is grown from — not just where it grows or how it is processed. The heirloom varietals on Yemen’s highland hillsides are found nowhere else in commercial cultivation on earth. Tuffahi, Dawairi and Udaini are three names that specialty coffee is only beginning to understand properly. For the full context on what makes Yemeni coffee distinct, read The Complete Guide to Yemeni Coffee: History, Regions and What Makes It Unique.
What are heirloom coffee varietals and why does Yemen have so many?
Heirloom coffee varietals are ancient plant varieties that evolved naturally — without commercial breeding, yield selection or genetic intervention. They are the original plants, not the products of decades of agricultural optimisation.
Most producing countries have had their coffee genetics rationalised over time. Varieties were selected for yield, disease resistance and standardised flavour. The diversity of the original plants was narrowed in favour of predictability and scale.
Yemen never went through that process. Its highland farms were never industrialised or consolidated. Each small family plot, in each microclimate, on each hillside valley, produced plants that evolved slightly differently over generations of isolation. The result is a country with one of the most genetically diverse coffee ecosystems on earth — a fact now recognised by researchers including those at World Coffee Research.
The three most recognised varietals are Tuffahi, Dawairi and Udaini. But they are only the beginning of what Yemen’s highlands contain.
What is the Tuffahi varietal?
Tuffahi is named from the Arabic word for apple — tuffah (تفاح) — and the name tells you something important about what to expect in the cup.
It is the most approachable of Yemen’s recognised heirlooms. The sweetness is forward. The acidity is mild. The fruit character is clean and rounded rather than wild or demanding. Tasting notes commonly include green apple, stone fruit and a honeyed quality in the finish.
For those new to Yemeni coffee, Tuffahi is usually the right starting point. It carries all the richness and natural sweetness of highland-grown, naturally processed coffee — but without the intensity that can initially challenge tasters unfamiliar with the origin. Pour-over and V60 methods bring out the best of what Tuffahi offers, allowing the fruit sweetness to come through clearly.
What is the Dawairi varietal?
Dawairi is, by the assessment of most specialty buyers who have worked with it, the most complex and distinctive of Yemen’s three main heirlooms.
The cup is wine-like in a way that goes well beyond a flavour descriptor. Dark fruit — dried cherry, blackcurrant, plum — sits alongside a structure that has more in common with a mature red wine than with anything most coffee drinkers encounter regularly. Acidity is higher than in other Yemeni heirlooms, but it integrates into the cup rather than standing apart from it. The finish is long.
As Ameen, founder of Hamdan Coffee, puts it:
“We make the coffee simple as it is. We don’t bring it as a juice — too many syrups, too much flavour, too much sweetness. The source of coffee should speak for itself.”
— Ameen, Founder, Hamdan Coffee
Dawairi is exactly what he means. There is nothing to add. Everything is already there.
What is the Udaini varietal?
Udaini takes its name from the Udain district in Yemen’s Ibb Governorate — a highland growing area that has produced coffee for centuries.
The character is deep and grounding. Where Dawairi reaches toward wine-like complexity, Udaini settles into the cup with quiet weight. Dark chocolate, dried fig and a rich, heavy body define most Udaini lots. Acidity is low. The sweetness is dark rather than bright — closer to dark treacle than to fresh fruit.
Experienced tasters often describe Udaini as the most intense of Yemen’s three primary heirlooms. It does not announce itself immediately. It reveals itself slowly — particularly as the cup cools. For brewing, ibrik or a slow cafetière allows the full body to develop without rushing the extraction.
Are these varietals found anywhere else?
No — not in commercial cultivation.
Tuffahi, Dawairi, Udaini and Yemen’s other heirloom varieties do not exist as commercial crops outside Yemen. The combination of genetics, centuries of local evolution and the specific highland terroir that shaped these plants cannot be transplanted. Growing Yemeni seed in another country would not produce Yemeni coffee. The plants would adapt to a different environment and produce something different.
This irreproducibility is central to understanding why genuinely sourced Yemeni coffee commands a premium — and why the farming communities that grow these varietals deserve support rather than imitation.
Why does Yemen’s coffee genetic diversity matter?
Most of the world’s commercial coffee production relies on a narrow genetic base — Bourbon and Typica derivatives dominate global supply chains. That narrowness creates a specific vulnerability. Climate change, new diseases and shifting rainfall patterns can devastate crops that share the same genetic weaknesses.
Yemen’s heirloom varietals may carry traits that matter to the future of coffee well beyond Yemen itself. Drought tolerance, heat resistance, disease resilience — characteristics that could become critical as growing conditions change across the coffee belt. Scientists and researchers are only beginning to document these genetics properly. If the farms that carry them are lost to conflict, economic collapse or land abandonment, those genes are gone permanently.
That is the weight behind a single cup of Yemeni heirloom coffee.
