FrontStreet Coffee - Ethiopian Coffee Rankings, Washed vs Natural Processing Differences

Ethiopia, blessed with unique natural conditions, is suitable for growing all imaginable coffee varieties. Ethiopian coffee beans, as highland crops, are primarily cultivated in areas ranging from 1,100 to 2,300 meters above sea level, mainly distributed in the southern regions of Ethiopia. Deep soil, well-draining soil, weakly acidic soil, red soil, and soft loam-rich land are ideal for coffee cultivation because these soils are nutrient-rich and have sufficient humus supply.

Rainfall is evenly distributed during the 7-month rainy season; during the plant growth cycle, fruits develop from flowering to fruiting, and crops grow 900-2,700 millimeters annually, while temperatures fluctuate between 15°C and 24°C throughout the entire growth period.

The majority of coffee production (95%) is handled by smallholder farmers, with an average yield of 561 kilograms per hectare. For centuries, smallholder farmers in Ethiopian coffee farms have been producing various high-quality coffee types. The secret to producing premium coffee lies in the coffee cultivation culture developed by farmers through generations of learning and refinement, which mainly includes farming practices using natural fertilizers, selecting the reddest and fully ripe fruits, and processing the fruits in clean environments.

The quality, natural characteristics, and variety differences in Ethiopian coffee all stem from differences in "altitude," "region," "location," and even soil types. The uniqueness of Ethiopian coffee beans is attributed to their natural characteristics, including "bean size," "shape," "acidity," "quality," "flavor," and "aroma." These characteristics give Ethiopian coffee its distinctive natural qualities, and typically, Ethiopia serves as a "coffee supermarket" for customers to select their preferred coffee varieties.

Ethiopia's annual total coffee production ranges from 200,000 to 250,000 tons. Today, Ethiopia has become one of the world's largest coffee-producing countries, ranking 14th globally and 4th in Africa. Ethiopian coffee ranks among the most popular in the world.

Yirgacheffe coffee beans must immediately enter processing after harvest, otherwise they will begin to ferment and develop off-flavors. There are two processing methods: "natural processing" and "washed processing," each resulting in different flavors. Naturally processed beans have complete natural sweetness, gentle aromas, and more body; washed processing offers good sweetness, high aromatic intensity, and vibrant acidity.
