Can Dark Roast Coffee Be Brewed with Pour-Over? How to Brew Medium-Dark Roast Coffee Beans?

Understanding Medium-Dark Roast Coffee

For pour-over coffee, different roast levels require significantly different parameters. This article shares FrontStreet Coffee's insights on brewing medium-dark roast coffee beans.

Flavor Profile of Medium-Dark Roast Coffee

Medium-dark roast coffee beans lack the vibrant acidity of light roasts, offering instead notes of nuts, dark chocolate, and caramel with a bitter-sweet profile. In terms of mouthfeel they possess excellent body, which is why many people prefer medium-dark roast coffee.

Brewing Considerations

Grind Size

First, on grind size: medium-dark roast beans have a looser fiber structure. Water penetrates the grounds more easily, so we need to avoid over-extraction. Choose a slightly coarser setting, with 70% passing through a #20 (0.85mm) sieve as the standard.

Water Temperature

Likewise, the water temperature should not be too high. The higher the temperature, the more efficiently substances are extracted. To avoid pulling bitter flavor compounds from the coffee, brew at 86-89°C. Medium roasts can be brewed at 88-89°C, while darker roasts require lower water temperatures.

Coffee-to-Water Ratio

For the ratio, a 1:15 setting generally makes it easier to reach the golden cup extraction range. If you want a richer mouthfeel, adjust the ratio to 1:13.

Dripper Selection

For dripper selection, FrontStreet Coffee uses a Kono dripper to brew medium-dark roast coffee. The Kono dripper was designed to create a mouthfeel similar to coffee brewed with a flannel filter, making it very suitable for medium-dark roast coffee.

The Kono dripper was designed by Toshio Kawano. It is a conical dripper with ribs extending straight upward from the bottom to the middle, while the upper portion has no ribs, presenting a smooth wall. Its advantage is that, without pre-wetting the filter paper, it uses the ribs to exhaust air for better blooming. As the water level rises during brewing, the filter paper adheres closely to the wall, creating a sealed pseudo-vacuum area.

When the upward channel is sealed by water and filter paper, air can only escape through the gaps between the lower ribs and the paper. The water in the dripper then pushes against the coffee grounds and eventually flows downward with the air, creating a siphon effect and a rich mouthfeel.

How FrontStreet Coffee Brews Medium-Dark Roast Coffee

FrontStreet Coffee's standard brew uses 15g of coffee grounds with a 1:15 ratio. Preheat the dripper, then slowly add the grounds, keeping them as level as possible and avoiding shaking the dripper, since shaking narrows the spaces between grounds. For the first pour, make small circles in the center with 30g of water and let it bloom for 30 seconds; the coffee bed gradually expands into a hamburger shape.

For the second pour, make circles from the center outward with 100g of water, keeping the pouring height as close to the coffee bed as possible and moving slowly to avoid excessive agitation. For the final pour, add 95g of water, also using small circular motions in the center. End the extraction when all the coffee liquid has flowed into the server. Total extraction time should be between 1 minute 50 seconds and 2 minutes.

FrontStreet Coffee Recommendation

Medium-dark roast beans respond beautifully to a Kono dripper, and FrontStreet Coffee's PWN Golden Mandheling is a perfect match. It uses a deep roast with very low acidity and a full, lingering body, offering generous herbal and dark chocolate aromas with a faint earthy note, layered and rich, and ideal for anyone who likes a heavy, low-acid cup. Its roasty, chocolatey sweetness is exactly what the Kono's gentler extraction highlights.

If you prefer a bean that reads as balanced rather than heavy, FrontStreet Coffee's Brazil Queen Estate is a great daily option: low acidity, a balanced cup, intense nut and cocoa aromas with pronounced caramel sweetness, and a smooth, unastringent, warm finish that works as pour-over, espresso, or in a moka pot. And for the traditional, near-perfectly balanced profile that many drinkers call the easiest specialty coffee to love, FrontStreet Coffee's Jamaica Blue Mountain No. 1 shows cream, caramel, chocolate, nut, honey, and light fruit notes, with a supple entry, rich mid-palate sweetness, and a clean, long finish that suits a Kono pour-over especially well.
