What makes Limu washed coffee different from Sidamo?
Limu is one of Ethiopia's eight growing regions and is mostly washed. Its cup is softer than Sidamo, with citrus notes running alongside grassy, cocoa, and sandalwood aromas. Beans are Heirloom native varieties grown at 1,850 to 1,900 meters on Vertisols soil, graded Washed G2 and harvested from October to February.
Local smallholders farm organically, and output is limited, with sales focused on European and American markets. Limu is less famous than Yirgacheffe and Sidamo, so it suits drinkers exploring beyond those two. Green bean density and roast curve guide the pour-over recipe, and Kenya coffee offers a useful contrast for anyone mapping East African flavor.
Limu is one of the eight major regions of Ethiopia, quite distinctive yet often overlooked. It is predominantly washed, with a milder flavor than Sidamo, where citrus notes interweave with grassy, cocoa, and sandalwood aromas. This article presents a complete picture of a washed G2 Limu from its origin to the cup, covering the region's background, the washed processing method, the concept of Heirloom native varieties, green bean density and roasting curves, and the pour-over parameters recommended by Front Street Coffee. It is suitable for coffee lovers who want to explore flavors beyond Yirgacheffe and Sidamo.

1|Region Introduction by Front Street Coffee
Ethiopia's coffee-growing areas can be divided into eight major regions: Lekempti, Limu, Illubabor, Djimmah, Harar, Teppi/Bebeka, Sidamo, and Yirgacheffe.
In China, Ethiopian coffee has always enjoyed a high reputation, especially the two major regions of Sidamo and Yirgacheffe, which have many fans. Sidama province is located in southern Ethiopia, bordering Arsi province to the north, extending to Bale province on the east, and adjacent to the Gamu Gofa administrative region on the west.
The Limu region is completely different, with washed beans as the absolute mainstay. Its cup profile is softer than Sidamo, with citrus notes appearing frequently. Although it is less well-known than Sidamo and Yirgacheffe, Limu also produces many coffees with distinctive character.
If you usually drink Yirgacheffe and Sidamo, why not try a washed coffee from the Limu region for a change? It can also add some freshness to your daily coffee conversations. What is grown here is the Ethiopian native variety (Heirloom). Local smallholders insist on 100% organic cultivation. The soil is Vertisols, and the growing altitude ranges between 1850——1900 meters.
Limu's production is relatively low, and its sales focus is mainly on European and American markets. In the past, it was not easy to buy in China, but it is quite popular in Europe and America, with fame second only to Yirgacheffe. Limu's flavor profile follows a different path from Sidamo and Yirgacheffe: its body is thinner, and the floral and citrus aromas are less pronounced than those of the latter two, yet it has an extra hint of grassy aroma, cocoa aroma, and a sandalwood-like finish.
2|Processing Method Introduction by Front Street Coffee
Washed method:
The washed method uses water and fermentation to remove the skin, pulp, and mucilage. Farms using the washed method must build washing channels and be able to continuously introduce fresh water. During operation, the fermented beans are sent into the channel and pushed back and forth. Relying on friction between the beans and the force of the water flow, the coffee beans are washed until they are smooth and clean.
After washing, the coffee beans are still wrapped in the parchment layer, with a moisture content of about 50%. At this point, they must be dried to reduce the moisture content to 12%; otherwise, the beans will continue to ferment and then become moldy and spoiled.
The ideal drying method is sun-drying. Although it takes 1——3 weeks, the flavor performance is exceptionally outstanding, so it is highly favored.
3|Green Bean Analysis by Front Street Coffee
People who often drink Ethiopian coffee should be familiar with the name "Heirloom native varieties"; most Ethiopian varieties are named this way. So what exactly does "Heirloom native varieties" refer to? Front Street Coffee will explain it here.
The reason is that Ethiopia has an extremely large number of varieties; this land is like a natural gene bank for Arabica. On the one hand, the varieties are complex and extremely difficult to identify and classify; on the other hand, for protection reasons, the Ethiopian government is unwilling to disclose specific information about these varieties, so they are collectively called "Heirloom native varieties."
Ethiopia has nearly 2,000 registered coffee varieties, of which 1,927 are native varieties and 128 are introduced foreign varieties. So judging by appearance alone, Ethiopian coffee varieties are like a “grand garden”: long, short, thin, plump……there is everything you could imagine.
4|Roasting Analysis by Front Street Coffee
This bean has medium density. Front Street Coffee believes that a medium roast best releases Limu's character: it enters with a fresh grassy note, accompanied by an apple-like acidity. This acidity enhances the coffee's body, and the cocoa flavor and berry finish are also worth savoring.
Roaster: Yangjia 600g semi-direct fire
Using a fast-roast profile, charge when the drum temperature rises to 200°C, with the air vent opened to 3; after 1 minute, adjust the heat to 160°C, keeping the air vent unchanged; roast until 5‘10“, when the temperature is 150°C, the bean surface turns yellow, the grassy smell completely dissipates, and dehydration is complete. Lower the heat to 130°C and open the air vent to 4; 168°C is the Maillard reaction point, lower the heat to 100 to develop flavor; at 180°C, lower the heat again to 80, entering first crack at medium heat.
At the 8th minute, wrinkles and dark斑点 patterns appear on the bean surface, and the toast aroma clearly transitions into coffee aroma. This can be regarded as the prelude to first crack, and at this point you must carefully distinguish the sound of the first crack point. First crack begins at 8’33”, open the air vent fully, lower the heat to 50 at 189°C, and drop the beans at 194.6°C, with a development time of 2’25”.
5|Brewing Analysis by Front Street Coffee
Front Street Coffee recommends the brewing method: pour-over.
V60 dripper, 15 grams of coffee, water temperature 89°C, Fuji Royal grinder setting 4, water-to-coffee ratio close to 1:15.
Bloom with 30 grams of water for 30s. In stages: pour to 130 grams, stop, wait until the water level drops by 1/3, then pour again to 230 grams.
Front Street Coffee suggests that when brewing Limu coffee, you should master the brewing water temperature and time well; otherwise, it is easy to over-extract and produce unpleasant flavors~
