Yemeni coffee varieties originally came from Ethiopia, but centuries of cultivation have made them varieties unique to Yemen itself. The very first coffee Europeans ever tasted was actually Yemeni Mocha — at one point, saying "Mocha" simply meant saying "coffee." Today, however, the supply of Yemeni Mocha keeps shrinking, with both its ports and growing regions caught up in war. The Yemeni coffee in FrontStreet Coffee's stock represents one of the last sizable batches in China, imported through Germany in 2017 while the port was still open; since then, no large quantities have appeared. In 2019, a Yemeni trader brought a small promotional batch into China, but quantities were minimal. To this day, the wild-character specialty beans of Yemeni Mocha remain deeply nostalgic for the FrontStreet Coffee team — the layered flavors of red wine, wildness, dried fruit, berries, and chocolate are utterly captivating.

What is Mocha Coffee?

Al-Matari is the most renowned coffee bean from Yemen, grown in the Bani Matari highlands west of the capital Sana'a, prized for intense, full-bodied flavors and distinct berry aromas.

When speaking of Yemeni coffee, "Mocha" inevitably comes up. Everyone has heard of "Mocha Coffee," but what exactly is "Mocha"?

The answer has several versions. Some say Mocha is a specific origin; for others, it conjures a sweet, chocolatey coffee drink. In fact, authentic "Mocha Coffee" is produced exclusively in the Republic of Yemen, on the southwestern Arabian Peninsula, where coffee grows on steep mountain slopes at altitudes of 3,000 to 8,000 feet — making it the world's most ancient coffee.

Meaning One:

As early as 500 years ago, Yemen was already producing coffee using ancient methods. In the early 17th century, the first batch of Yemeni coffee sold to Europe was exported through the small ancient port of "Mocha," astonishing European drinkers, who came to call the delicious coffee from Mocha Port "Mocha Coffee" — the origin of the term.

Ethiopia, Yemen's neighbor across the Red Sea, also shipped coffee through Mocha Port, which is why Ethiopian natural-processed coffee is often labeled Mocha as well (as in Mocha-Harrar, Ethiopia Harrar). Today the old port of Mocha — now called Al Makha — has long been abandoned to sediment, and exports have shifted to the northwestern port of Hodeida. Yet people have grown so accustomed to the name that its reputation still resounds far and wide.

Meaning Two:

Over time, some people began using "Mocha" as a simple nickname for coffee. Later, because the aftertaste of Mocha coffee resembles chocolate, "Mocha Coffee" came to refer to espresso drinks mixed with chocolate.

Meaning Three:

In 1933, the Italian Alfonso Bialetti invented the first Moka pot (MokaPod), giving every household a simple, convenient way to brew Italian-style coffee, and it quickly became the first choice for home brewing. Calling BIALETTI the father of the Moka pot is no exaggeration!

So although they share the name "Mocha," Mocha beans, the Moka pot, and the mocha on an Italian espresso menu represent three entirely different things.

FrontStreet Coffee finds that deeply roasted Yemeni coffee often shows a chocolate-like caramel sweetness. So when you see the words "Mocha Coffee," they might refer to pure Yemeni coffee, to neighboring Ethiopian coffee, or simply to something else entirely. Either way, for discerning coffee connoisseurs, only genuine Yemeni coffee truly qualifies as "Mocha Coffee."

The term "Mocha" has many spellings: Moka, Moca, and Mocca are all common. On Yemeni coffee sacks and documents, up to four local spellings have been observed — "Mokha," "Makha," "Morkha," and "Mukha" — all meaning the same thing.

Yemeni Mocha Coffee

Yemeni Mocha is the originator of the world coffee trade and made an indispensable contribution to spreading delicious coffee across the globe. In the 17th century, Yemeni Mocha — known as "Arabia Coffee" (the origin of the later name "Arabica"!) — crossed the oceans to Italy and other Catholic countries of Europe. For more than 150 years thereafter, Yemen remained the only coffee origin exporting to Europe.

In those early days, conservative Catholic countries often regarded extraordinarily wonderful things as evil, and coffee was once burdened with inexplicable guilt. It was not until a coffee-loving Pope in the Vatican declared coffee a Catholic beverage and blessed those who drank it that coffee began to spread widely through Europe. Although Ethiopia was the first country to discover coffee, it was Yemen that truly made coffee flourish.

A Living Relic in the Coffee World

To this day, Yemeni coffee farmers still produce coffee the same way they did 500 years ago.

Coffee cherries grow naturally on the trees, with no artificial fertilizers or pesticides. In summer they are nourished by the mountain slopes' sparse rain and mist, flowering and fruiting; in the dry winter, mature cherries are left hanging on the trees to air-dry naturally — a highly unusual and rare practice, possible only thanks to Arabia's extremely dry climate and intense sun. In any other origin, the same approach would leave the cherries rotting on the branch.

Ripe or dried cherries fall from the trees naturally or are shaken and picked off. Coffee farmers — who make up nearly a quarter of Yemen's total population — spread the pulp-covered cherries on rooftops, in low sheds in front of their homes, or even directly on the muddy ground to drink in the fierce dry winter sun. Once the skin and pulp have dried, old-fashioned stone mills (two stones stacked together) grind away the hardened husks and pulp — and just like that, the coffee is processed.

Even now, a small number of Yemeni farms still use animals — camels, donkeys — to power their stone mills. Compared with Central and South American countries processing huge volumes with advanced machinery, or even neighboring Kenya with its comparatively short coffee history, Yemeni Mocha is practically a living relic. And here is a thought: the Yemeni coffee you drink today is essentially no different from the "Arabia Coffee" that European nobles and merchants enjoyed centuries ago in Europe's oldest cafés on Venice's St. Mark's Square.

Unlike the washed processing used in most coffee origins, Yemeni coffee is processed entirely as a natural. The stone-mill dehulling (crushing between two stones) leaves broken beans mixed in, so the appearance is uneven. Green beans often contain small twigs, small stones, even dried insects (screened out during roasting). What it offers in return is some of the most unique, rich, and fascinating complex aromas in the coffee world: "red wine fragrance, wildness, dried fruit, blueberry, grape, cinnamon, tobacco, sweet spices, wood notes, even chocolate..." Every adjective in the book has been used to describe Yemeni Mocha!

Because the beans are dried with the pulp intact, coffee cherry flavors have the chance to "seep into" the beans. When the fruit falls on the dry soil of the highlands, it also absorbs flavors of the surrounding organic matter. Add the "sun flavor" imparted by the intense Arabian winter sun (you can smell something similar in a quilt dried outdoors), the natural fermentation notes of the ripe pulp, a slight earthiness... and the roughly 300,000 coffee farms spread across altitudes from 3,000 to 8,000 feet, plus the ancient, 100% organic processing, and you get the one-of-a-kind Yemeni Mocha.

Yemeni Mocha Coffee Regions

Among commonly seen Yemeni Mochas, Mokha Mattari is the most famous. Produced in Bani Matar (also written Bany Mattar) province, Mattari is a high-altitude coffee typically showing excellent red wine aroma, dried fruit flavors, and full body, with chocolate-caramel sweetness when roasted dark.

Because of Yemen's political instability in recent years and sharply reduced production, the celebrated Mokha Mattari has become a target for adulteration, with instances of blending in lower-grade inferior beans. Today even beans labeled "Mattari" are not guaranteed quality. Good Mattari beans are small, and the green beans carry an intoxicating sweet wine aroma with moderate ripe-fruit fermentation. Excellent Mattari will never disappoint a true coffee connoisseur!

Mokha San'ani is a blend from tens of thousands of small farms on the mountain slopes near the capital San'a. It grows at a slightly lower altitude than Mattari; generally its body is thinner and its acidity lower, but it shows good fruit aromas and often better ripe-fruit and wild flavors than Mattari. From experience, San'ani quality varies enormously, and inferior lots can taste flat, earthy, or over-fermented. Careful cupping and selection are essential work for coffee importers — absolutely no cutting corners.

Mokha Ismaili is one of the traditional ancient varieties, grown at very high altitudes above 6,500 feet. The beans are rounder and smaller than Mattari, with full body and high complexity, and it generally outperforms Mattari. It is the lowest-production, most expensive Yemeni Mocha (and Yemeni Mocha is never cheap to begin with). High-quality Mokha Ismaili is produced in the Hirazi area — not as famous as Bani Matar, but by local standards the best-regarded growing region — on high mountain slopes, with Hirazi's highest plots reaching 8,000 feet!

Mokha Rimi comes from the Djebel Remi area (also spelled Raimi or Rayma), with quality similar to San'ani. In my experience, Mokha Rimi usually carries slightly heavier fermentation flavors and occasionally shows an astonishingly rich raisin sweetness. Roasted properly, the beans smell like opening a jar of dense fruit jam.

Mokha Yafeh is produced in Yemen's southern Yafeh (also Yaffe) province. It is an uncommon Yemeni Mocha and represents the country's only "southern flavor." Production is limited, and most is exported to neighboring United Arab Emirates, so it is rarely seen in the specialty coffee market.

One coffee expert put it this way: "Yemeni Mocha flavors are too diverse — not only do different origins, varieties, and batches differ, but even each sack, even each cup, tastes different." Because of that complexity and variability, roasting Yemeni Mocha to its optimal flavor is a genuine challenge! Light-medium roasting reveals fruity sweetness, gentleness, and warm natural fermentation notes; deep roasting reveals rich red wine aroma and a bittersweet chocolate aftertaste — both worthy of savoring again and again, a flavor that "lingers for days." No wonder so many devoted coffee connoisseurs name Yemeni Mocha as their favorite!

Confusing Nomenclature

Yemeni coffee naming still has no universal standard and no official grading system. Locals maintain their own internal classification with hundreds of coffee codes and names, but these are not used commercially (for export). In commercial markets, Yemeni Mocha typically follows one of two naming conventions: "origin name" or "variety name."

Yemeni Mocha Mattari and Yemeni Mocha San'ani use origin naming, indicating production in Bani Matar province and on the slopes near the capital San'a respectively; Yemeni Mocha Ismaili uses variety naming, with its production located in Hirazi, southwest of Bani Matar.

For such a unique coffee, FrontStreet Coffee recommends brewing Yemeni coffee with a flannel filter. Below, FrontStreet Coffee shares its brewing parameters and flavor notes for Yemeni coffee.

FrontStreet Coffee's Recommended Yemeni Mocha Brewing Method

Recommended Device: Flannel Filter

Flannel cloth extracts the coffee's delicious compounds slowly and gently, producing a cup with round, deep flavors — that is the greatest charm of the flannel filter. Because flannel's capillary pores are larger than filter paper's, it retains some of the coffee's oils, unlike paper, which usually filters them all out. Coffee brewed through flannel is therefore richer and smoother than coffee brewed through paper.

Moreover, since flannel's capillary pores are coarser and filtration can occur at any position below the water line (whereas filter paper only filters through the gaps of the dripper), flannel drains slightly faster than a typical dripper-and-paper setup (note: flannel's flow rate differs between its two sides!).

Parameters: Grind size 5M (70-75% pass rate on a Chinese-standard 20-mesh sieve), water temperature 88°C, coffee-to-water ratio 1:15, total extraction time 2 minutes 30 seconds.

Technique: Bloom with 30g of water for 30 seconds; pour in stages up to 100g; once the water level drops and the coffee bed is about to be exposed, continue pouring up to 225g to finish.

Flavor: Full-bodied and smooth, rich dark chocolate, persistent caramel sweetness; as the cup cools, spice and berry notes emerge.

FrontStreet Coffee Recommendation: Craving Those Wild, Winey Naturals? Try the Huakui

If Yemen's dried-fruit-and-wine character speaks to you, FrontStreet Coffee's natural-process Huakui is the closest experience available right now. It comes from the Hambella growing region in Guji, Sidamo, on a 200-hectare farm using traditional natural processing: cherries are raised on elevated drying beds for 21 days, turned constantly for even drying, with defective or moldy beans hand-sorted every three to five days before the dried husks are hulled off. Roasted medium-light, it opens with a delicate fermented wine note, florals, citrus, and mango, with rich honeyed sweetness, a cocoa undertone with a whisper of spice, a thick body, and a long finish — a vivid echo of what made Yemeni Mocha legendary.
