手沖繞圈快慢,會影響咖啡風味嗎 Will the speed of pouring circles during pour-over brewing affect the flavors of the coffee?
目錄:
手沖咖啡時繞圈注水可幫助均勻萃取,但繞圈要怎麼繞,繞快、繞慢 對沖煮出的咖啡風味會有影響嗎?
When pouring water in a circle by hand, it can help to extract evenly, but how to pour the circle, fast or slow, will it affect the flavor of the brewed coffee?
繞圈速度不同小實驗
JC咖啡小實驗,同樣咖啡粉量、粉水比、水溫、時間、繞圈方式,但只有繞圈速度不同,一次快、一次慢,來喝看看會有什麼不一樣。
Justin coffee did an experiment. We tried the same amount of coffee powder, powder to water ratio, water temperature, time, pouring circles, but with different speed: one fast and one slow. Come and see what the difference will be.

這次採用的豆子是:
衣索比亞 耶加雪菲 荷芙莎村 G1 水洗慢乾│淺焙
風味: 檸檬 蜂蜜 檸檬糖 酸甜感奔放 細緻柔軟 橙色水果 細膩多汁
Coffee bean we used is:
Ethiopia Gediyo Yirgacheffe Hafursa G1 Washed Slow Dry
Flavor: lemon, honey, lemon sugar, sweet and acidity, delicate and soft, citrus, delicate and juicy
-------
繞圈快版,喝起來:
檸檬、甘甜、酸質明亮、body略薄
Flavors of fast pouring circles
Lemony, sweet, bright acidity, slightly thin body
繞圈慢版,喝起來:
蜂蜜、檸檬糖、甜感佳、body滑順、酸甜多汁
Flavors of slow pouring circles
Honey, lemon candy, good sweetness, smooth body, sweet and juicy
小編是偏好慢版,喝起來平衡多汁、風味飽滿。
We prefer the slow version, which is balanced, juicy and full of flavor.
小實驗結論
探討二者的差別,快版的萃取率較低、慢版的萃取率較高,雖然水柱擾動快似乎會增加萃取率、但在上述小實驗中,卻是較低的萃取率。這時我們想到一個重要因素,水溫的變化。我們知道水溫對萃取的重要性,水溫高、萃取率高。在繞圈快的同時、也讓水溫降低了,這個因素大於擾動的因素;讓繞圈快版的萃取率降低了。
To explore the difference between the two, the extraction rate of the fast version is lower, and the extraction rate of the slow version is higher. Although fast water column disturbance seems to increase the extraction rate, in the above experiment, it is a lower extraction rate. At this time we think of an important factor, the change of water temperature. We know the importance of water temperature to extraction; high water temperature will have high extraction rate. At the same time as the fast pouring, the water temperature is reduced. This factor is greater than the disturbance factor, so the extraction rate of the fast version is reduced.
所以我們手沖咖啡時,可以靜心養氣,慢慢繞圈,享受一杯風味飽滿、香甜好喝的咖啡。
So when we brew pour-over coffee, we can calm down and nourish our energy, slowing the pouring circle, and enjoy a cup of coffee with a full flavor and a sweet taste.
