What does define arabica mean for Ethiopia Limu Washed G2?

Limu is one of Ethiopia's eight growing regions and mostly produces washed coffee. Compared with Sidamo, it enters more mildly and often carries citrus and grassy aromas. The beans are Heirloom native varieties grown by smallholders at 1,850 to 1,900 meters on Vertisols soil, with harvest running from October to February.

A documented roast on a 600g semi-direct-fire roaster charges at 200°C, hits first crack at 8 minutes 33 seconds, and drops at 194.6°C. V60 pour-over parameters accompany the curve, giving a repeatable recipe. For drinkers used to Yirgacheffe and Sidamo, washed Limu offers a different tasting experience worth comparing.

Limu is a low-key yet noteworthy presence among Ethiopia's eight major producing regions, primarily washed, with a milder flavor than Sidamo, often carrying citrus and grassy aromas. This article provides a complete overview of the Limu washed G2's regional background, washed processing flow, Heirloom native variety characteristics, along with the practical roast curve on a Yangjia 600g semi-direct-fire roaster and V60 pour-over parameters. From charge temperature of 200°C to first crack at 8 minutes 33 seconds and drop at 194.6°C, every heat and airflow adjustment is documented, making it a useful reference for coffee enthusiasts who want to explore Ethiopia's lesser-known regions, and providing a reusable recipe for everyday brewing of Limu beans.

1|Region Introduction:

Ethiopia's coffee-growing landscape can be divided into eight major regions: Lekempti, Limu, Illubabor, Djimmah, Harar, Teppi/Bebeka, Sidamo, and Yirgacheffe.

In the domestic coffee community, Ethiopian beans have always enjoyed a solid reputation, with the Sidamo and Yirgacheffe regions being especially sought after. Sidamo Province is located in southern Ethiopia, bordered by Arsi Province to the north, extending east to Bale Province, and with the Gamu Gofa administrative region to the west.

Beans from the Limu region are mostly washed, with a milder entry than Sidamo and a relatively common citrus profile. Although its fame doesn't match Sidamo or Yirgacheffe, it also produces many distinctive coffees. For those accustomed to Yirgacheffe and Sidamo flavors, switching to a washed Limu offers a completely different tasting experience and adds more coffee topics to discuss. The local crop is the Ethiopian native variety (Heirloom), and smallholders insist on 100% organic cultivation. The soil is Vertisols, and the altitude ranges from 1850 to 1900 meters.

Limu's output is not high. In the past, it was mainly sold to European and American markets, making it hard to find domestically, but it is quite popular in Europe and America, with fame second only to Yirgacheffe. Limu's flavor profile takes a different route from Sidamo and Yirgacheffe: the body is thinner, and the floral and citrus notes are less flamboyant than the latter two, but it has an extra layer of grassy and cacao notes, with hints of sandalwood also detectable.

2|Processing Method Introduction

Washed:

The core idea of washed processing is to use water and fermentation to remove the skin, pulp, and mucilage together. Farms using the washed method must build washing channels and ensure a continuous supply of fresh running water. In practice, the fermented beans are poured into the channel and repeatedly pushed, relying on friction between the beans and the scouring force of the water to wash the coffee beans until smooth and clean.

After washing, the coffee beans are still wrapped in the parchment layer, with a moisture content as high as 50%. They must be dried to bring it down to 12%, otherwise the beans will continue to ferment and become moldy.

The ideal drying method is sun-drying. Although it takes a long time—about 1 to 3 weeks—the finished flavor is exceptionally good, making it widely favored.

3|Green Bean Analysis

Those who often drink Ethiopian coffee should be familiar with the term 【Heirloom native variety】. The vast majority of Ethiopian varieties are labeled with this name because the number of local varieties is simply too large—like a natural gene bank of Arabica. On one hand, there are so many varieties that identification and classification are extremely difficult; on the other hand, the Ethiopian government, for protection reasons, is unwilling to disclose information about these varieties, so they are collectively called 【Heirloom native variety】.

There are currently nearly 2,000 recorded Ethiopian coffee varieties, of which 1,927 are native varieties and 128 are introduced varieties. So judging by appearance alone, Ethiopian coffee varieties are like a “grand garden”—long, short, thin, plump, there's everything……

4|Roast Analysis

This bean has medium density, and a medium roast best releases Limu's regional character. The entry is a fresh grassy note, accompanied by an apple-like acidity. This acidity makes the coffee's overall mouthfeel seem fuller, and the cacao and berry finish is quite intriguing.

Roaster: Yangjia 600g semi-direct fire

Using a fast-roast profile, charge at 200°C, airflow set to 3, after 1 minute adjust heat to 160°C with airflow unchanged, roast until 5‘10“ at 150°C, when the bean surface turns yellow, the grassy smell completely disappears, and dehydration is complete. Adjust heat to 130°C and open airflow to 4; 168°C is the Maillard reaction point, lower heat to 100 to develop flavor; at 180°C lower heat again to 80, entering first crack at medium heat.

At the 8th minute, wrinkles and dark streaks appear on the bean surface, and the toast aroma clearly turns into coffee aroma, which can be defined as the prelude to first crack. At this point, listen carefully for the sound of first crack. At 8’33”, first crack begins. Open airflow fully, lower heat to 50 at 189°C, roast to 194.6°C and drop, with a development time of 2’25”.

5|Brewing Analysis

Recommended brewing method: Pour-over.

V60 dripper, 15g coffee, water temperature 89°C, Fuji Royal grinder setting 4, water-to-coffee ratio close to 1:15.

Bloom with 30g water for 30s, then in stages: pour to 130g and stop, wait for the water level to drop by 1/3, then pour again to 230g.

When brewing Limu, be sure to control the water temperature and time well, otherwise it's easy to over-extract and produce unpleasant flavors~
