How Does the Coffee Beans Process Shape Washed Yirgacheffe Pour-Over Flavor?

For a medium-light roasted washed Yirgacheffe such as the Gotiti Cooperative bean, use 90-91°C water, a caster-sugar grind size, and a three-pour extraction. Yirgacheffe, a small town in Ethiopia's former Sidamo Province, is known for crisp mouthfeel and striking acidity, with citrus, floral aroma, honey-like sweetness, and a tea-like finish. An iced pour-over follows the same idea, with the coffee-to-water ratio, ice amount, stirring, and time all controlled.

The region's character comes from three things: high-altitude growing conditions, naturally mixed coffee varieties, and a clean coffee beans process. Traditional coffee often emphasized body alone, while Yirgacheffe shifted expectations toward bright acidity and aroma. After Ethiopia redrew its administrative divisions in 1995, Sidamo ceased to exist as a region and Yirgacheffe fell under the Gedeo Zone, though its beans kept the same white floral and lemon-citrus profile.

Yirgacheffe, with its fresh floral aromas and bright citrus acidity, has become one of the most watched coffee regions in the global coffee scene. Starting from the region's divisions, varietal characteristics, and the differences between washed and natural processing methods, this article systematically sorts out the reasons behind Yirgacheffe's style, and uses a medium-light roasted washed Gotiti Cooperative bean as an example to give specific pour-over parameters and flavor descriptions: 90-91°C water temperature, caster-sugar grind size, and a three-pour extraction. At the end, a complete iced pour-over recipe and steps are also included, covering the coffee-to-water ratio, ice amount, stirring technique, and extraction time control, helping coffee lovers reliably recreate a cup of Yirgacheffe full of juicy fruitiness even in summer.

Yirgacheffe was originally just a small town in Ethiopia's Sidamo Province. The coffee beans produced there had a crisp mouthfeel and striking acidity, which won the favor of a large number of coffee lovers, and today it is also one of the most important regions in the global coffee industry.

In the past, traditional coffee often emphasized only body, but the emergence of Yirgacheffe refreshed many people's understanding of coffee flavor. Bright citrus acidity, elegant floral aromas, a honey-like sweet finish, and a tea-like aftertaste after swallowing have captivated many domestic consumers who grew up in tea-drinking culture.

Front Street Coffee attributes Yirgacheffe's deliciousness to three points: the high-altitude growing environment, naturally mixed coffee varieties, and pure, traditional processing methods.

As Front Street said in the previous article, Yirgacheffe was originally a small town under Sidamo Province in Ethiopia. But after Ethiopia redrew its administrative divisions in 1995, Sidamo no longer existed as an administrative region, and Yirgacheffe was accordingly placed under the Gedeo Zone.

Later, coffee traders noticed that beans produced in the Yirgacheffe area had a particularly unique white floral aroma and lemon-citrus notes, and were extremely popular among consumers. So many people would specially select coffee beans from the Yirgacheffe producing area before export in hopes of selling them at a better price.

By 2009, the Ethiopia Commodity Exchange implemented a certification in several specific producing areas such as Wenago, Yigacheffe, Kochere, and Gelena~Abaya, dividing them into Yigacheffe A, which has the classic Yirgacheffe flavor, and Yigacheffe B, which does not. In other words, the Yirgacheffe you drink in a cafe today may not actually come from the place called Yirgacheffe, yet it still bears the name Yirgacheffe, just as Yonghe Soy Milk does not necessarily come from Yonghe.

Most of the Yirgacheffe we drink today refers to a producing area or regional concept. In the Yirgacheffe area, there are many cooperatives that centrally process coffee beans, among which names such as Kochere, Worka, Gotiti, Chelelektu, Misty Valley, and Konga are relatively prominent and often mentioned.

When trading these beans, green bean merchants generally label them with Yirgacheffe plus the cooperative name to indicate that the beans come from a certain village or cooperative in Yirgacheffe. Most Ethiopian coffee is tied to place names, but not all categories are classified by place name. For example, the Sidamo Huakui 8.0 on Front Street's bean list is actually a nice name given by a domestic green bean trader to highlight its selling point.

Ethiopia is the birthplace of all coffee varieties, so even today there are still a large number of wild or native coffee varieties that have not yet been discovered and certified. Because the number of varieties is huge and complex, most Ethiopian farmers do not subdivide varieties when planting coffee trees. Instead, they plant and harvest them mixed together, and collectively call these varieties Heirloom.

It is precisely because of different varieties that the size of coffee cherries also varies. Front Street has observed that coffee beans from Ethiopia often appear uneven in size. This is normal and is also a major characteristic of coffee beans from this region.

In Ethiopia, limited by climate and conditions, people usually adopt the most traditional processing methods when obtaining coffee beans: washed and natural.

Yirgacheffe's ability to form such a distinct style is due not only to innate terroir conditions, but also to a large extent to the washed processing technology introduced from Central and South America by the Ethiopian government in 1972. Farms using the washed method must build washing channels and continuously introduce fresh water, resulting in higher production costs. During processing, the fermented beans are placed in the channel and moved back and forth. With the friction between the beans and the force of the water flow, the coffee beans are washed smooth and clean. Every step removes impurities and defective beans, so the green bean quality is more uniform, and the final trading price is also higher than that of coffee processed by the natural drying method.

The processing flow for washed coffee beans is: after harvesting, first remove bad cherries, then remove the skin and pulp, place them in a clean water tank to ferment and break down the mucilage, then wash them with clean water and sun-dry them. Front Street Coffee found through cupping that the washed processing method can give coffee beans very clean and bright acidity and flavor, and also allows people to intuitively feel the quality level of the coffee beans.

Natural coffee beans means that after the coffee cherries are harvested, bad cherries are first removed, and then they are directly sun-dried until the moisture content reaches an appropriate level before being bagged and packed. After cupping, Front Street Coffee found that coffee beans processed by the natural method have a very full sweet-and-sour sensation and also carry a soft fermented aroma.

The Yirgacheffe area is very rich in water resources, so most coffee beans from this producing area are mainly washed. Among them, the most representative is the "Medium-light Roast - Yirgacheffe Gotiti Cooperative Coffee Beans" sold by Front Street Coffee.

Because Yirgacheffe coffee beans are grown at high altitudes, the beans are relatively hard, and medium-light roasting will not greatly change the structure of the coffee beans themselves. Therefore, for high-altitude coffee beans with floral and fruity notes like Yirgacheffe, Front Street uses a water temperature of 90-91°C and a caster-sugar-like grind size (80% passing rate on China's No. 20 standard sieve).

Three-pour extraction: For the first pour, use 30g of water to bloom for 30 seconds; for the second pour, add 95g of hot water; when the coffee bed drops halfway, begin pouring the third pour of 100g, until all the coffee has finished dripping. Note to start pouring from the center point, maintaining a small stream and gentle force in circles throughout to avoid uneven extraction.

Gotiti pour-over coffee flavor performance: After grinding, elegant jasmine and citrus-like acidity can be smelled. After extraction, the first sip shows clear bright lemon acidity, with a prominent sugarcane sweetness. As the temperature drops, it presents a green tea-like mouthfeel and a long finish.

Sharing the parameters for iced pour-over coffee

As for what parameters to use for iced pour-over, Front Street once mentioned a formula in an article: Iced pour-over = coffee grounds (fine grind) + 10 times hot water + 5 times ice cubes . Here, combining a medium-light roasted coffee bean of the fruity-acid type, paired with 91-93°C water temperature, small-stream circular pouring, and a three-pour technique, so that the extraction time falls between 1 minute 50 seconds and 2 minutes, allows you to easily brew a pot of iced coffee with excellent flavor.

The juicy sensation that appears in coffee is usually the rich fruity aroma smelled combined with the sweet, sour, and juicy feeling in the mouth when drinking, reminding people of the experience of eating a certain fruit. Applied to today's iced pour-over topic, this means that we need to extract both the acidic aromatic compounds in the early stage and pursue the sweetness in the middle and later stages in order to satisfy a sweet-and-sour juicy mouthfeel. Such a requirement cannot be met by water flow agitation alone, so Front Street also added one action: stirring.

Coffee beans: Front Street washed Gotiti Cooperative

Dose: 15 grams

Coffee-to-water ratio: 1:11 (160 grams hot water)

Ice: 75 grams

Grind size: EK43s setting 9.5 (about 22 clicks on C40)

Dripper: Hario V60

Three pours: 30 grams, 90 grams (+ stirring), 45 grams

Before pouring, first put the ice cubes in the server, then add all the coffee grounds. The first blooming pour remains unchanged: keep a small stream and pour 30 grams in circles from the center outward.

After 30 seconds, begin pouring 90 grams of hot water in circles with a larger stream while raising the water level. When the timing scale shows 120 grams, stop pouring. Use a small spoon to draw 5 circles along the dripper wall in one direction, then wait for the coffee liquid to slowly flow down.

When the water in the dripper is about to run out, use the same small-stream, small-circle technique as the first pour to finish the remaining 45 grams of hot water, until all the coffee liquid has dripped through. Then you can remove the dripper and end extraction. The time will roughly fall within the range of 1 minute 55 seconds to 2 minutes 5 seconds.

The Front Street Gotiti brewed this way first gives a mouth-watering sweet-and-sour sensation like yellow peach, sweet orange, and pomelo on the palate, with an overall tendency toward yellow stone fruit notes. Because of the added stirring action, in addition to rich fruity acidity, the coffee also carries a clear, moist sweetness, and under the cooling of the ice cubes, it is like drinking a refreshing cup of fruit tea.
