According to the roasting log of Japanese coffee master Shigeru Taguchi: on April 7, 2012, 253 grams of Yirgacheffe were roasted as a French roast, dropped 30 seconds after second crack began. Defective beans ran 0.5%, yielding 202 grams of roasted coffee - a dehydration rate of 19.8%.

First, preheat the roaster to 200°C, kill the flame and let it cool to just over 150°C, then relight and charge the beans. Bean preheating took 6 minutes 46 seconds. Dehydration completed at 180°C. First crack began at 199°C, around 12 minutes 36 seconds in; it turned intense at 203°C and fully ended at 208°C, at 14 minutes 40 seconds. Second crack started at 19 minutes and ended at 222°C, at 22 minutes 40 seconds; after another 40 seconds the beans were dropped at 23 minutes 20 seconds. French roast leaves the beans brownish-black.

Why do some roasters use light roast for Yirgacheffe?

Specialty coffee's 4321 theory: the quality of a cup is determined 40% by variety, cultivation, and processing; 30% by roasting; 20% by brewing equipment; and 10% by the brewer's technique.

Roasting shapes a specialty coffee's flavor more than almost anything else. Roasted beans earn their following from the aromas and textures formed under high-heat chemistry. Inside the roaster, green beans pass through drying, thermal decomposition, and cooling; across the endothermic and exothermic phases, first and second cracks occur, producing floral and fruity aromatics and rich mouthfeel.

Of course, roast degree must also be matched to the beans' processing method.

Everyone's experience and preference differs. Light and medium roasts draw different expressions from Yirgacheffe, and no single degree is inherently better.

Is Yirgacheffe suitable for dark roast?

Light roast makes Yirgacheffe's tropical fruit aromas more prominent and abundant, with a gentle apple-like acidity on entry. That acidity actually reinforces the coffee's body, making the bitterness fragrant and memorable. Coffee is, at heart, a fruit - and keeping those sweet-sour fruit flavors intact after high-temperature roasting is exactly what makes Yirgacheffe special.

Whatever the country, the roaster remains the deciding factor: their personal understanding of the beans and their own preferences shape the whole approach.

Whether to go light or medium is decided by the palates of the roaster and the drinkers. (Source: Zhihu user "Ai Wo Ka Fei," China's first ready-to-drink specialty coffee)

How Professionals Read Yirgacheffe Roast Levels

Here are the approaches of several experienced roasters:

1. BLANK ZHOU from Australia:

I roast about 1 to 1.5 tons of YIRGECHEFFE (FTO G-2) monthly. I adjust the roast within 4, 6, and 8 seconds after second crack begins. The output is aimed mainly at single-origin espresso...

2. HAPPYBOB:

I drop just before second crack - roughly midway between the last sound of first crack and the first of second crack, about 40-45 seconds after first crack ends - for single-origin use. I also use Yirgacheffe for espresso, but a touch darker: 15 seconds into second crack.

3. fisher:

I drop at the end of first crack, loving the low bitterness, intense citrus, pleasant fruit acidity, and clean mouthfeel there. Many people, though, find the acidity too sharp and the body too thin at that degree.

4. Brother Niao:

The whole roast runs about 9 minutes, dropping at the end of first crack. Fast-roasting plus a light profile on high-moisture beans easily yields mottled "flower bean" looks - and I actually prefer that "ugly" appearance on Yirgacheffe. The advantage is minimal flavor loss and very rich mouthfeel; the disadvantage is that sloppy execution leaves insufficient dehydration and astringency, and fast roasting can preserve defects along with the treasures. Roasting is the art of balancing excellent flavors against defect flavors. My shareable experience: higher-quality beans suit fast roasting, while lower-grade lots need an extended curve to adjust their flavors, or the defects and aggressive notes run rampant.

5. horsezhang:

Huky500 roaster, dropped 30 seconds after first crack.

6. FrontStreet Coffee Roasting:

On a Yangjia roaster: preheat to 200°C, cool to 195°C, charge the beans. Reach 150.8°C at 5 minutes 23 seconds, completing dehydration. First crack begins at 180°C at approximately 8:48 and completes at 10:57.

Is Yirgacheffe suitable for espresso?

I once tried washed Yirgacheffe as an SOE (Single Origin Espresso), pulling shots one week after a medium roast. The aroma was overwhelming - and the acidity ferociously strong.

Personally, I don't think it works as a straight espresso; it shines as an Americano or iced Americano instead. The acidity is pleasant and lively, the mouthfeel refreshing and crisp - highly recommended in summer.

Cupping Notes: Light-Roast Natural vs. Washed Yirgacheffe

Dry Aroma Differences:

Natural Yirgacheffe: light fermented wine aroma, spicy fragrance

Washed Yirgacheffe: jasmine florals, lemon or lime citrus

[Cup with 8g of coffee to 150ml of 93°C water; steep 3-4 minutes until a crust forms]

Mouthfeel Differences:

Natural Yirgacheffe: the natural process reads as somewhat complex - light fermented wine notes, heavier bitterness, a much richer mouthfeel, honey sweetness, cocoa notes with a trace of spice, thick body, persistent aftertaste.

Washed Yirgacheffe: washed acidity is brighter - lemon-like - with a lighter, fresher mouthfeel, more obvious citrus aromatics, and a black-tea sensation later in the cup.

Similarities: both share fruit acidity of the lemon and citrus family

Pour-over Data

Natural Yirgacheffe:

15g of coffee at 89°C, Fuji grinder setting 4, V60 dripper, 1:15 ratio. First pour 30g, bloom 28 seconds. Second pour to 110g, then a third pour to 225g total, discarding the tail water. Extraction time: about 2:06.

Washed Yirgacheffe:

15g of coffee at 92°C, 1:15 ratio, V60 dripper. First pour 30g, bloom 35 seconds. Second pour to 130g, then a third pour to 225g total, discarding the tail water. Extraction time: about 2:15.

Brewed this way, Yirgacheffe delivers that delightful sensation of flowers brushing against your taste buds and olfactory cells.

FrontStreet Coffee Recommendation

Want to taste these roast-level differences for yourself? FrontStreet Coffee's Washed Yirgacheffe daily bean is the ideal starting point. Yirgacheffe is a small town in southern Ethiopia's Sidamo province at roughly 1,700-2,100 meters, with coffee planted above 1,800 meters - among the highest growing zones on earth. Famous for unmistakable white floral notes and lemon-citrus acidity, it became so celebrated that in 2010 the Ethiopian Commodity Exchange formally separated it from Sidamo as its own appellation. Expect white jasmine, bright citrus and lemon acidity, and a graceful tea-like finish - light, elegant, and clean, like a refreshing lemon tea.

For a washed lot with a village story, FrontStreet Coffee's Worka (Guodingding) Cooperative coffee comes from the Worka zone at Yirgacheffe's southeastern edge. Once part of the YCFCU's Worka cooperative, it became an independent cooperative in 2012 with about 300 member farmers as buyers worldwide hunted for traceable single sub-regions. With pulp removed before drying, its own character reads clean and transparent: citrus and lemon tones wrapped in elegant white florals, bright and delicate from start to finish.

And to hear the natural-process side of the cupping notes above, FrontStreet Coffee's Natural Red Cherry shows it beautifully: only fully ripe, defect-free cherries are dried whole on raised beds - turned every 2-3 hours early on to prevent over-fermentation - then sun-dried for three to five weeks before the fruit is stripped away. Drying with the fruit on keeps classic Yirgacheffe character and adds tropical fruit: peach, cocoa, honey, and lemon, with citrus-like acidity, berry juiciness, honeyed sweetness, and cream-smooth body. Brew any of them on a V60 at 90-91°C, 15g of coffee, a 1:15 ratio, and a fine caster-sugar grind.
