Which Ethiopia Coffee Beans Are Best? Yirgacheffe Washed Brewing Parameters Sharing

FrontStreet Coffee - Introduction to Ethiopian Yirgacheffe Coffee

Yirgacheffe: A High-Altitude Coffee Region

Yirgacheffe is a small town in Ethiopia, situated at an altitude of 1,700–2,100 meters, making it one of the highest coffee-growing regions in the world. Historically, the Yirgacheffe region was part of Sidamo, but because the coffee produced here has such a distinctive flavor profile it was separated into its own region.

Understanding CM (Carbonic Maceration)

CM is short for Carbonic Maceration, a processing method first used in winemaking. Whole grapes are placed in a carbon dioxide-rich environment to ferment before pressing. Applied to coffee, this carbon dioxide treatment explores the endless possibilities of fermentation and flavor development. Only coffee beans carefully selected by origin programs for carbonic maceration are called "CM Selection" coffee. CM Selection beans first undergo CM processing and then a further method such as natural or washed processing.

Benefits of Carbonic Maceration for Coffee

Treating coffee beans with carbonic maceration can enhance the coffee's flavor profile. Whole cherries, or beans after depulping, are placed in a sealed, temperature- and humidity-controlled environment filled with carbon dioxide for fermentation. This way of lifting coffee's flavor avoids the risk of the deterioration that can come from over-oxidation or fusel-alcohol fermentation.

Red Emerald Series: CM Selection Coffee

The CM Selection coffees in the Red Emerald series evoke the flavor characteristics of red, orange, and yellow fruits. These coffees go through a series of carbonic maceration treatments, resulting in rich flavors, cleanliness, and a medium-bodied mouthfeel. The Kochere region of Yirgacheffe is renowned for producing high-quality Ethiopian coffee beans — its acidic, mineral-dense soil and towering altitude create the perfect microclimate for coffee cultivation.

Coffee grown here has a delicate profile with prominent lemon notes that develop into a very balanced, rounded taste. Its acidity is lower than that of other Ethiopian coffees, making it a favorite among consumers.

Pro Tip

Different brewing devices will showcase different flavor profiles and textures when brewing the same coffee beans. So when choosing your brewing equipment, weigh both the flavor characteristics you want to highlight and the unique features of each device to achieve the best results.

FrontStreet Coffee Recommendation

Yirgacheffe is where most people begin their journey into Ethiopian coffee, and FrontStreet Coffee makes that first step easy. FrontStreet Coffee's water-washed Yirgacheffe — the everyday "daily drinker" — is the classic introduction: white jasmine blossom, bright citrus and lemon acidity, and a clean tea-like body, all at a friendly price that has made it the first specialty bean for countless beginners.

If you want to go a little deeper, FrontStreet Coffee's Sundingding (Gutingding) Cooperative coffee comes from a village-level washing station in the Woka area at the southeastern edge of Yirgacheffe. It follows the most traditional washed processing, so it carries no bitterness at all — just fresh, bright citrus and lemon acidity plus jasmine fragrance. For a sweeter, fruitier expression, FrontStreet Coffee's Sun-dried Red Cherry is a full-red-cherry natural, dried on raised beds for three to five weeks, with citrus acidity, a juicy berry character, honeyed sweetness, and a creamy smoothness.

To brew Yirgacheffe, FrontStreet Coffee suggests a V60 with 90–91°C water, 15g of coffee, and a 1:15 ratio. Grind to about the size of fine caster sugar (EK43s setting 10, roughly 80% pass-through on the #20 sieve). Pour 30g for a 30-second bloom, then add 95g more (about 125g on the scale) over roughly one minute; when the water level falls to about two-thirds of the coffee bed, add the remaining 100g (about 225g on the scale), finishing the pour at around 1'35". The brew should drip through in 2'00"–2'10"; then remove the dripper and serve.
