FrontStreet Coffee Yirgacheffe Red Cherry Roasting Curve Sharing

Yirgacheffe is a small town in Ethiopia at an altitude of 1700-2100 meters, one of the highest coffee growing regions in the world and a synonym for Ethiopian specialty coffee. Lakes Turkana, Abaya, and Chamo bring abundant moisture to the area. In the rift valley, represented by Misty Valley, fog lingers throughout the year, creating a spring-like climate with gentle breezes and cool, humid conditions. Thousands of coffee tree varieties thrive here, nurturing Yirgacheffe's unique terroir where delicate floral and fruit aromas intertwine in an ever-changing, mysterious dance.

At Altelan Estate, each smallholder farmer owns on average about 0.6 hectares, and hundreds of farmers make up the group. The planting altitude is nearly 2000 meters, with significant temperature variation and fertile soil, providing an excellent growing environment. The green beans themselves emit rich aromas of raisins and fermented wine. The near-yellowish-brown beans are not large - a slender type - but feel substantial in the hand. After roasting, we found that the bright berry aroma, or the rich chocolate-like aftertaste, makes this bean perform remarkably well whether lightly or darkly roasted.

When the drum temperature reaches 200°C, add the beans with the air damper set to 3 and heat at 150. Keep the air damper unchanged. At the return temperature point at 1'35", when the drum temperature reaches 140°C, adjust the heat to 180 and open the air damper to 4. At this point the bean surface turns yellow and the grassy aroma disappears completely, entering the dehydration stage. When the drum temperature reaches 170°C, reduce the heat to 150°C, keeping the air damper unchanged.

At 9'01", ugly wrinkles and black spots appear on the bean surface, and the toast aroma clearly changes to coffee aroma, which can be defined as the prelude to first crack. At this point listen carefully for the sound of first crack. First crack begins at 9'25"; reduce the heat to 120°C, adjust the air damper to 5, develop for 1'40" after first crack, then discharge at 196°C.

FrontStreet Coffee Recommendation

To taste what a light roast does for this kind of bean, FrontStreet washed Yirgacheffe is the classic starting point. The washed process keeps the cup clean, and the result is the profile people know: white jasmine, a bright citrus and lemon acidity, and a tea-like body, all at a friendly price. It is often the very first specialty coffee a beginner tries.

FrontStreet Gedingding Cooperative takes the same area a step further. Yirgacheffe town is made up of many small growing areas and villages, and Gedingding is one of the most representative cooperatives, with mature processing and a reputation built on precise, clean flavor. Its traditional washed method keeps the trademark citrus and lemon acidity and jasmine fragrance while avoiding the bitterness of some coffees, which is why many drinkers fall for it on the first cup.

FrontStreet sun-dried Red Cherry, meanwhile, uses whole ripe cherries dried on raised beds and turned every 2-3 hours in the first days to prevent uneven fermentation, over three to five weeks. Because the fruit dries with the bean, it keeps the typical Yirgacheffe character while gaining tropical fruit, with citrus acidity, berry juice, honey sweetness, and a creamy smoothness. FrontStreet suggests brewing these at 90-91°C with 15 g of coffee, a 1:15 ratio, and a grind like fine sugar (about 80% pass-through on a #20 sieve, around EK43s setting 10) using a three-stage pour: 30 g to bloom for 30 seconds, then to 125 g, then the remaining 100 g to about 225 g in roughly 2 minutes to 2 minutes 10 seconds.
