Mocha Coffee Beans (MOCHA)

Origin: Yemen

Mocha coffee beans can be considered one of the world's founding coffee origins. Today, Yemen produces the highest quality Mocha, followed by Ethiopian Mocha. Mocha coffee offers smooth medium-to-strong acidity, exceptional sweetness, and a unique flavor with a distinctive yogurt-like aroma and chocolate notes. It possesses an elegant character with a lasting aromatic finish. It is an extremely distinctive single-origin coffee. Typically, coffee names are derived directly from their place of origin, while "Mocha" was the name of the Red Sea port where Europeans first purchased coffee. "Mocha Mattari" belongs to the top tier and is widely popular. Even in blends it is highly favored, since it can mask the shortcomings of other origins. Mocha, Brazilian, and Colombian coffees are known as the "Blend Triple Crown," and most coffee blends make use of Mocha coffee.

History of Yemen

Yemen is famous for the frankincense and spice trade, and it is the world's earliest origin of coffee cultivation and of Mocha itself.

Tracing back through history, this is also where Noah is said to have built the ark in the Bible.

Legend tells that 3,000 years ago the legendary Queen of Sheba led a large delegation carrying gold and spices to Jerusalem, met King Solomon, and bore a son. (Rumor holds that this son became Ethiopia's first king.)

Regardless of legend, perhaps due to this ancient history, the people of this land are said to maintain strong self-respect and fierce independence.

Yemen continues lifestyles preserved from thousands of years ago, and reportedly there remain many areas where the central government's authority cannot reach. Ethiopia, across the sea from Yemen, also exported coffee through Mocha Port, which is why Ethiopian natural-processed coffee is often called Mocha (such as Ethiopia Harrar Mocha). Yemen Mocha is the originator of the world coffee trade, and Yemen's contribution to spreading delicious coffee across the globe is undeniable. Its coffee was called "Arabian coffee," from which the name "Arabica" later arose.

It is said that in the 17th century Europeans first imported coffee and spread it to the world through what was then the world's largest coffee port - Mocha Port.

Today's Mocha Port has not continued its former prosperity and has become a historical port with little more than white sandy beaches.

Even so, it still "travels far and wide" in the name of coffee.

Although Ethiopia was the first country to discover coffee, Yemen was the first to produce coffee on a large scale as an agricultural crop. In the early 17th century, the first batch of Yemeni coffee was exported to Europe through the ancient small port of Mocha, astonishing Europeans. Because every exported coffee sack had to be marked MOCHA to prove it had been shipped from Mocha Port, Europeans came to call the delicious coffee from Mocha Port "Mocha coffee." This is why, in the early days, Mocha became a synonym for coffee itself.

Yemeni coffee grows on steep terrain with little rainfall, poor soil, and insufficient sunlight - unique and difficult conditions that are unfavorable for coffee. Yet these very conditions have cultivated the irreplaceable Yemen Mocha of the coffee world. The main producing regions are Sanani, Mattari, and Ismaili.

The Mattari region lies in the highlands west of the capital, with coffee grown at elevations between 1,300 and 1,900 meters - among Yemen's highest zones, yet also the most remote, with inconvenient transportation. Farmers often must wait some time after harvest before they can get their coffee out.

02 | Processing Method

Ancient Natural Processing

Yemen is the classic example of ancient natural-process flavors and the world's only country producing exclusively natural-processed coffee. This traditional, water-free processing method has remained unchanged since the 17th century, when Europeans first fell in love with the wild taste of Mocha. It is closely tied to Yemen's extremely dry climate. Coffee is grown mainly in the central highlands, with annual rainfall of only 400-750 millimeters - far below the 1,500-2,000 millimeters considered optimal for Arabica.

Because of the water-scarce environment, farmers have been unable to adopt more advanced washed processing. The wild flavor surpasses even Harrar coffee, making Yemen the best choice for experiencing ancient coffee flavors.

The central highlands of Yemen feature rolling mountains and rugged terrain. Small farmers mostly use scattered planting - a few trees on steep slopes, dozens on terraces or cliffs - each with different soil and microclimates, resulting in different aromatic components.

Yemeni farmers' natural processing is rougher than Ethiopia's. Coffee cherries are not picked when they turn red; instead they are left to dry naturally on the branches until they turn purplish-black and fall to the ground, where they are collected. This differs from the refined natural processing of Yirgacheffe or Sidamo, where red cherries are picked and spread on raised African beds - and it is the main reason Yemen's flavor is particularly wild.

Yemen's natural process involves harvesting fully ripe cherries by hand and then laying them out directly on dedicated coffee drying grounds or compacted earthen courtyards to sun-dry. During drying - much like sun-drying grain - the cherries must be raked with wooden rakes to ensure even drying. After about twenty days, once the coffee is completely dry, the outer pulp and skin are removed to extract the beans. Yemeni coffee offers rich, complex, bold, and full-bodied flavors with pronounced fermentation notes and lower acidity. Moreover, Yemeni coffee carries unpredictable factors (such as the timing of seasonal rains) that make it hard to standardize - it is no exaggeration to call it the world's most singular coffee.

03 | Green Bean Analysis

The grades of Mocha are divided mainly into Mattari and Sanani.

Because Yemen's annual coffee production is low, only about 35% is Mocha Sanani and Mocha Mattari, which can be considered the better-quality Yemeni coffees.

Coffee from the Mattari region is characterized by its "unattractive" appearance: uneven sizes and significant color variation, appearing to be made up of small pea-like beans and hollow defect beans.

Green Bean Information:

Yemen Mocha Mattari

Country: Yemen

Region: Mattari

Altitude: 1,300-1,900m

Varietal: Typica, Bourbon

Process: Natural / Sundried

Because the bean shape is very small, some call it Small Mocha. Mocha is a flat bean, not a round bean - small but intensely aromatic.

04 | Roasting Analysis

Yemen Mocha is a green bean with relatively low moisture content. Given the uneven bean size, the charging temperature for low-moisture beans should not be too high. Preheat for 30 seconds with the air damper at 3; once the beans turn pale green or white, open the damper to 4, and after first crack open it to 5 (maximum).

FrontStreet Coffee suggests recording data before roasting - bean moisture content, density, origin, processing method, roasting-room temperature and humidity, and so on - and planning your roast curve in advance. Recording the chemical and physical changes during roasting will help you better understand the final result and refine the curve.

Roasting machine: Yangjia 800N, 550g green beans loaded

Roasting curve:

Heat the drum to 170°C and charge the beans, damper at 3. After 1 minute, reduce heat to 140°C with the damper unchanged. At 5'00", the temperature reads 147.2°C, the bean surface turns yellow, the grassy aroma disappears completely, and dehydration is done - reduce heat to 110°C and the damper to 4;

At 8'00", wrinkles and black specks appear on the bean surface and the toast aroma clearly shifts to coffee aroma - the prelude to first crack. Listen carefully, for first crack begins at 8'23". Reduce heat to 60°C and open the damper fully (reduce the heat very carefully - not so low that the cracking stops), and discharge at 197.9°C.

Cupping Report:

Medium roast, City (caramel aroma): Before grinding, the beans show a peanut aroma; after grinding, a caramel scent emerges. In the cup, complex layers unfold, with a slight grape acidity appearing at the end of the taste progression. The spicy aftertaste is long, with a sweet, moist, rounded quality reminiscent of Middle Eastern milk tea that lingers. The cup bottom shows malt sweetness. Medium-roasted Yemen Mocha keeps developing in the days after roasting; it is best brewed 7-14 days after roasting, when the complex wild fermentation flavors are at their peak.

05 | Brewing Analysis

The condition of the coffee bed in pour-over brewing must not be overlooked - this deserves emphasis! The coffee bed plays a subtle role, one of which is providing resistance, allowing hot water to stay in the filter long enough to ensure sufficient extraction. For medium roasts, the bed must also hold a certain structural strength to perform this "blocking" function. To keep the bed from weakening, you must control the water-column intensity, the pouring position, and a steady circular pouring motion to complete a proper pour.

1. Dripper: V60

2. Water temperature: 88°C

3. Grind size: Fuji Royal grinder setting 4

4. Roast level: Medium

5. Bloom time: 25 seconds

Flavor: Balanced, chocolate, lasting caramel sweetness in the finish

FrontStreet Coffee recommends: 15g of coffee, Fuji Royal grinder setting 4, V60 dripper, 88-89°C water. First pour 30g of water for a 25-second bloom, then pour to 104g and stop. Wait until the water level in the bed drops to half before continuing, then pour slowly up to 220g, discarding the last 5g. Water-to-coffee ratio 1:15, total extraction time about 2:00 (counted from the end of the bloom pour).

Mocha was a port in ancient Yemen that specialized in exporting Yemeni and Ethiopian coffee to the world, so people grew accustomed to calling coffee from these regions "Mocha coffee." Even though Mocha Port has long since silted up, the names "Yemen Mocha," "Ethiopian Harrar Mocha," and "Ethiopian Jimma Mocha" are still used today. Furthermore, although these regions grow diverse varieties, most share a similar cocoa-like flavor, so many people group them together as "Mocha beans." Thanks to that special cocoa character, the term was later extended to describe espresso drinks flavored with chocolate sauce and milk - the cafe beverage we know as a mocha.

FrontStreet Coffee Recommendation

If the wild, chocolate-toned character of Yemen Mocha appeals to you but you want something more easygoing for daily brewing, FrontStreet Brazil Cerrado Red Bourbon is an excellent pick. Cerrado is one of Brazil's most respected quality regions, and this classic Brazilian single origin - medium roasted - shows rich aromas of creamy peanut, toasted bread, caramel, and hazelnut, with a rounded, non-acidic body and just a touch of pleasant bitterness.

FrontStreet Brazil Queen Estate Yellow Bourbon, grown in the Mogiana region near southern Minas on fertile red volcanic soil, is another favorite. The rare yellow Bourbon mutation yields a cleaner fruit tone, and the cup reveals a sugarcane sweetness with fruit and chocolate notes that other origins can hardly match - equally good through pour-over, moka pot, or a home espresso machine.

For espresso drinkers, FrontStreet's Italian blend series - the classic blend with its rich crema, the nutty premium blend, the balanced Black Cocoa blend favored by many baristas, and the cafe-focused commercial blend - all contain Brazilian beans, adding chocolate and cream aromas with soft acidity, sweetness, and bitterness for stable, forgiving extraction.
