Introduction:This article will delve into the washed Geisha coffee beans from Colombia’s El Mitrá Estate, and conduct a practical extraction comparison using three common brewing devices — the Hario V60, Bingtong filter, and siphon (syphon). We not only record the precise parameters of each device but also analyze the unique flavor profiles they bring out to help you find the most suitable brewing method for this bean.
A certain coffee brand recently acquired a batch of washed Geisha beans from Colombia’s El Mitrá Estate. After a period of rest, it officially began testing multiple pour-over brewing methods. These high-altitude Geisha beans from the Chinchiná region in Caldas Province are grown at elevations between 1700 and 1850 meters, falling under the SUPREMO grade. They exhibit notable aromatic potential and rich complexity, making them highly suitable for exploring how different brewing devices influence flavor.
For this practical test, we selected three widely popular coffee brewing tools: the Hario V60, Bingtong filter, and traditional siphon, each simulating different flavor directions and mouthfeel characteristics. Through detailed parameter settings and segmented pouring strategies, we were able to observe the performance differences of each device with the same beans and compile recommended choices for different brewing objectives.
First up is the Hario V60, a classic pour-over dripper known for its brisk flow rate and a degree of controllability. The V60 features a large bottom outlet hole and spiral-shaped internal ridges that help evenly channel the coffee liquid, but can also lead to under-extraction due to overly fast flow if not balanced with appropriate grind size and segmented pouring. The parameters for this test were: 15 grams of coffee, medium-fine grind (approximately 58% extraction through a Chinese standard No. 20 sieve, close to BG 5T), water temperature at 90°C, and a brew ratio of 1:16. Pouring was done in a classic three-stage method: first, a 35g bloom for 30 seconds, followed by adding 91g of water to reach a total of 126g for the first pour, then waiting until the water level dropped near the coffee bed before pouring again to 240g to finish. The total extraction
The second brewing device is the Ice Eye dripper. Its unique filter structure features ribs arranged in a step-like vertical pattern. The bottom of the dripper leaves the filter paper partially suspended, while the area near the rim is almost fully in contact with the filter, creating a semi-enclosed space. This design utilizes residual air vents to mimic an immersion-style environment under high water temperatures or large water flows, effectively preventing under-extraction caused by overly fast drainage. The tested parameters are similar to those of the V60: 15 grams of coffee grounds, medium-fine grind (BG 5T, 58% extraction), water temperature at 90°C, and a brew ratio of 1:16. The pouring method also follows a multi-pour approach—first blooming with 30 grams of water for 30 seconds, then pouring up to 123 grams for the first pause, followed by additional pouring to reach 240 grams to finish. The total brew time is approximately 1 minute and 45 seconds. This method highlights more intense fermented aromas, with flavors dominated by citrus, tropical fruits, and mango. The sweetness is more direct and pronounced, making it suitable for those who prefer fruity and sweet notes.
The last device tested was the siphon (vacuum) pot, a traditional brewing tool that uses steam pressure differentials to extract coffee. It is known for producing a rich, full-bodied flavor with an oily mouthfeel. To use it, heat water in the lower chamber until boiling, then insert the upper chamber so the rising steam pressure forces the hot water to mix with the coffee grounds. For this test, a slightly higher dose of 20 grams of coffee was used, ground to a medium-fine consistency (BG 6M, approximately 48% extraction rate). Water temperature remained at 90°C, with a brew ratio of 1:14. The specific steps included: adding 280 grams of water to the lower chamber and heating it; placing the coffee grounds in the upper chamber and stirring about ten times after the water rises; stirring lightly five more times at the 40-second mark to promote even extraction; and then removing the heat source at the 50-second mark and stirring again to encourage rapid coffee liquid return. The entire process took about 1 minute and 30 seconds. The resulting coffee has tangy-sweet notes of grape, peach, and citrus, along with a distinct oolong tea character. It has a prominent oiliness, a thick mouthfeel, and a long-lasting aftertaste.
Based on the practical testing of all three devices, if you want to emphasize aroma and layered complexity in your coffee, the Hario V60 is the top choice. If you prefer a fruitier and sweeter profile, the Ice Eye dripper offers a rounder and fuller taste experience. For those who favor a richer body and smoother texture, the siphon pot meets these needs perfectly. Regardless of which method you choose, it’s recommended to adjust grind size and water temperature based on personal taste preferences, and pay attention to pouring speed and uniformity to fully unlock the potential of this sun-dried Geisha.
