What Went Wrong With My Yirgacheffe Pour-Over?

You’re trying to enjoy a cup of Yirgacheffe, but something’s off. No matter how you adjust your pour-over technique — playing with water temperature, grind size, or brew time — the coffee just tastes unpleasantly sour. That’s exactly what happened to one coffee enthusiast who received a shipment of Yirgacheffe from seller happybob. Despite tweaking their method, the coffee remained sharp and uncomfortable on the palate. The issue wasn’t the technique, but something earlier in the process.

The key issue? The coffee was roasted too lightly. According to the roaster, a machine cleaning error led to an accidental under-roast, resulting in a cup that was overly acidic and unbalanced. Once informed, the roaster quickly offered a replacement.

What Actually Happened With the Yirgacheffe Batch

The first batch of Yirgacheffe arrived tasting overly sour, no matter the pour-over adjustments. The drinker tried altering pour speed, water temperature, and grind size, but the discomforting acidity persisted. They contacted the seller, happybob, who explained the problem: the roast was accidentally too light due to machine maintenance during roasting. That light roast brought out harsh, unpleasant acidity rather than the expected bright, balanced cup. Happybob apologized and sent a replacement immediately.

How Roast Level Affects Yirgacheffe Flavor

Yirgacheffe is known for its vibrant citrus, floral notes, and tea-like body — classic characteristics of a well-executed light to medium roast. But when the roast is too light, those bright acids dominate without the sweetness or balance to back them up. In this case, the unintended very light roast exaggerated the sourness, making the coffee unpleasant despite being a generally well-regarded origin. Proper roasting develops sugars and mellows acids to achieve the signature Yirgacheffe profile: think white jasmine, lemon, and a soft tea finish.

How to Brew Yirgacheffe via Pour-Over (As Described)

In the second attempt, the coffee was brewed using a pour-over method, though the brewer admits they didn’t control temperature precisely. Here’s what they did:

• Water temperature: Around 90°C during bloom and brew (ideal range is typically 90–91°C, per FrontStreet’s recommendation).
• No cooling between bloom and brew — the same hot water was used throughout.
• Bloom: Used 90°C water (standard practice is to bloom with slightly cooler water to avoid over-extraction of acids).
• The goal was a quick brew due to time pressure, and finer details like exact timing or pouring structure weren’t documented.
• The brewer noted they’d try a lower temperature next time to better highlight Yirgacheffe’s citrus notes.

While the method lacked precision, it reflects a common pour-over setup: V60 filter, pre-warmed vessel, standard bloom, and continuous pouring. The key takeaway is that temperature control and roast level have a massive impact on how Yirgacheffe’s bright acids and floral qualities are perceived.

Frequently Asked Questions

Why did my Yirgacheffe taste so sour?

The sourness likely came from an overly light roast, which amplifies acidity without balancing sweetness or body. In this case, a roasting error led to a batch that was unintentionally under-roasted, making the coffee taste sharp and unpleasant despite being a typically vibrant origin.

What’s the best water temperature for Yirgacheffe pour-over?

The recommended brewing temperature is 90–91°C. Using water that’s too hot can over-extract acids, making the coffee taste overly sour. In the described brew, 90°C was used throughout, but lowering it slightly might help achieve a smoother, more balanced cup.

Does roast level really change how Yirgacheffe tastes?

Yes. Yirgacheffe shines at light to medium roasts, where the roast develops enough sweetness to balance its natural citrus and floral acidity. A very light roast can make it taste overly sharp and unbalanced, as was the case in this shipment.

How should I adjust my pour-over if my Yirgacheffe tastes too sour?

Try lowering your brew temperature slightly (aim for around 90°C), and ensure your roast is medium-light rather than very light. You can also extend brew time or adjust your grind to slightly coarser if over-extraction is suspected. If the coffee is simply too acidic by nature, a different roast batch may be required.

What’s the standard pour-over method for Yirgacheffe?

FrontStreet Coffee recommends using a V60, 15g coffee to 225g water at a 1:15 ratio, with a grind size around EK43s setting 10 (fine, like sugar). Bloom with 30g water for 30 seconds, then pour in stages: 95g, then 100g, aiming for total brew time around 2:10.
