How should Geisha coffee be brewed at home?
Geisha 5.0 is a sun-dried bean from the Buku Abel processing plant in Ethiopia, and it carries the strawberry and creamy aroma the Geisha series is known for. Front Street Coffee adjusted the roast curve for its high moisture and high density, then tested four extraction methods: hot pour-over, iced pour-over, ice drip and cold brew.
The flavor does shift between seasons because coffee is an agricultural product, so the new crop differs from earlier Geisha lots even when the plant and process stay the same. Climate and soil change how the beans develop. Cooling the brew over ice or dripping it slowly concentrates the fruity notes and keeps the creamy body from turning heavy in summer.
Geisha 5.0 has arrived as promised. This sun-dried bean from the Buku Abel processing plant in Ethiopia has won over many coffee lovers with its strawberry and creamy aroma. But does the new-season Geisha still taste the same as before? The Front Street Coffee roaster adjusted the roasting curve for its high moisture content and high density, and offers four extraction methods—hot pour-over, iced pour-over, ice drip, and cold brew—so that the gentle fruity charm of Geisha 5.0 can be fully released in summer. This article will start with the origin story of Geisha and then break down the specific parameters and operational details of each brewing method one by one, helping you find the cup that suits you best.
At summer dusk, the soft glow of sunset on the horizon always reminds people of a highly sought-after coffee bean—Geisha 5.0. Its fruity aroma is like the orange-and-yellow interwoven twilight, its rich berry juice sensation resembles the pink-and-purple blended sunset clouds, and its creamy, silky body is as gentle as a summer breeze. How can this tenderness of Geisha coffee be delivered to the palate? Front Street Coffee usually uses four methods to achieve it.
First, let’s talk about the origins of Geisha coffee beans
In 2017, the Ethiopian green bean company DW submitted its coffee beans to the TOH (the Taste Of Harvest) green bean competition held by the African Coffee Association. Among them, a bean from the "Buku Abel" processing plant won the TOH Ethiopia championship with its rich strawberry and creamy aroma. This batch of green beans was subsequently introduced to the domestic market by a green bean trader in Beijing, and because it carried the champion halo, it got the name "Geisha." In the same year, Li Jianfei from Beijing used this 2017 champion Geisha coffee bean to win second place in the China region of the World Coffee Brewing Championship (most other competitors that year used Gesha), and the domestic coffee circle therefore firmly remembered this bean.
Is Geisha 5.0 still the same Geisha as before?
No. The climate is changing, and coffee beans are ultimately agricultural products, so their flavor naturally changes accordingly. Although all series of Geisha are produced at the "Buku Abel" processing plant and all use the sun-dried processing method, the flavor performance of the coffee beans varies due to climate, soil, and other conditions. Therefore, DW distinguishes Geisha by version each year: Geisha 2.0 was released in 2018, Geisha 3.0 and 3.1 in 2019, Geisha 4.0 in 2020, and Geisha 5.0 in 2021.
How does the Front Street Coffee roaster bring out the gentle character of Geisha 5.0?
New-season green coffee beans have a relatively high moisture content, and moisture affects heat conduction during roasting, making insufficient dehydration likely. At this point, the coffee beans may already be fully developed on the surface while the core is still underdeveloped. To avoid this problem, Front Street Coffee recommends extending the dehydration phase when roasting Geisha 5.0 (that is, the time from the turning point to the yellowing point); at the same time, in order to highlight the sweetness and fermented character brought by the sun-dried process, the Front Street Coffee roaster also appropriately lengthened the Maillard phase (that is, the time from the yellowing point to first crack). Geisha 5.0 is grown at an altitude of 2,250 m to 2,350 m, and the beans are relatively hard, so the heat must be increased before first crack to avoid prolonging first crack development and causing the coffee’s sweet-and-sour flavors to be lost.
How does Front Street Coffee (FrontStreet Coffee) bring Geisha’s tenderness to the palate? | Hot pour-over method & iced pour-over method
In order to fully extract the rich layering of Geisha 5.0, Front Street Coffee uses a higher water temperature together with a finer grind, but to prevent over-extraction caused by high temperature, it chooses a faster-flow dripper, such as the V60 dripper. The V60 dripper is conical at 60 degrees, and the conical angle allows the coffee grounds to gather together. When pouring, the water flow also automatically converges toward the center of the dripper, ensuring enough contact time between water and coffee grounds, thereby extracting a suitable coffee liquid. In addition, the ribs on the inside of the V60 dripper extend in a clockwise spiral from the bottom to the top, leaving sufficient space between the filter paper and the dripper, so water flow is smooth. Combined with the large hole design at the bottom, the overall flow rate is faster than many drippers.
The parameters and brewing method for hot pour-over are as follows: water temperature 90°C, coffee-to-water ratio 1:15, coffee dose 15 g, medium-fine grind (80% passing through a Chinese No. 20 standard sieve).
First, use 30 g of water to fully wet the coffee bed into a "hamburger" shape and let it bloom for 30 seconds; for the second pour, at 1 minute 00 seconds on the timer, pour water until it reaches 125 g, then wait for the water level to drop to two-thirds of the coffee bed before pouring the third stage; for the third stage, at 1 minute 40 seconds on the timer, pour water until it reaches 225 g. After the coffee liquid has fully dripped through, the total extraction time is 1 minute 59 seconds. After extraction is complete, gently swirl to make the coffee liquid fully uniform before tasting.
The parameters and brewing method for iced pour-over are as follows: water temperature 91°C, coffee-to-water ratio 1:10, coffee dose 15 g, medium-fine grind (85% passing through a Chinese No. 20 standard sieve), plus 100 g of ice cubes. Also use a three-stage pour: the first stage pours 30 ml and blooms for 30 seconds, the second stage pours 60 ml, and the third stage pours another 60 ml. Then pour the coffee liquid into a cup containing 100 g of ice cubes and shake evenly.
| Ice drip method
When Front Street Coffee makes ice drip coffee, the coffee powder chamber holds 60 g of ground coffee, and finally 600 ml of coffee liquid is extracted, giving a coffee-to-liquid ratio of 1:10. For grind size, choose a setting slightly finer than for pour-over; judged by a No. 20 sieve, the passing rate is about 85%. The ratio of ice-water mixture is 1:1, and the flow-control valve is set to a flow rate of 7 drops every 10 seconds. The entire extraction process lasts about 6 to 8 hours. After extraction, bottle it and chill it for 12 hours before drinking.
| Cold brew method
Taking the cold brew regularly produced by Front Street Coffee as an example, the coffee beans are ground slightly finer than for pour-over, that is, 75% to 80% passing through a Chinese No. 20 standard sieve. Visually, this is about the coarseness of fine granulated sugar, corresponding to 9.5 to 10 on an EK43s, and for a manual grinder such as the C40, about 22 to 26 clicks.
Next, pour the ground coffee into a clean container, which can be a dedicated cold brew pot or a mineral water bottle. Add room-temperature water at a coffee-to-water ratio of 1:10, stir evenly, seal with plastic wrap, and place in the refrigerator to steep for more than 8 hours (best within 12 hours). Finally, filter out the coffee grounds with filter paper, and the cold brew portion is ready.
The coffee-to-water ratio for cold brew is usually what everyone cares about most. Front Street Coffee believes that if you drink it directly without adding anything else, you can use a coffee-to-water ratio of 1:12 to 1:13. Black coffee made in this range has the highest palatability, and the aroma can also be fully released. However, considering that fresh milk will be added at the end, the coffee concentration needs to be increased so that it will not be "diluted" too much later. Therefore, Front Street Coffee recommends making it at a ratio of 1:10 to 1:11.
Finally, Front Street Coffee offers one more reminder: generally speaking, for the sake of flavor experience and health and safety, whether it is ice drip or cold brew, for any extraction method carried out in a low-temperature environment, Front Street Coffee recommends drinking it within 5 days (counting from the production date).
