手沖新手的苦惱，光要挑選濾杯就眼花撩亂，陶瓷濾杯、塑膠濾杯價格差好多，對咖啡的萃取有影響嗎？
Pour-over coffee brewing beginners sometimes are troubled with choosing the right coffee filters, as the price of ceramic filter cup and plastic filter cup is much different. Does it affect the extraction of coffee?
濾杯對咖啡的萃取的影響
我們知道溫度對萃取有很大的影響，溫度高、萃取率高，溫度低、萃取率低。濾杯的材質對溫度有影響嗎？經過我們實驗發現，在其他條件不變之下，只有濾杯不一樣時，即陶瓷濾杯 VS 塑膠濾杯，同時沖煮下，卻發現喝起來非常不同。
We know that the temperature has a great influence on the extraction: high temperature will have high extraction rate; low temperature will have low extraction rate. Does the material of the filter affect the temperature? Through our experiment: the ceramic filter VS plastic filter, we try to keep other conditions unchanged and only the filter is different. We found that when brewed at the same time, coffee tasted very different.
陶瓷濾杯
以20克咖啡粉
注入 337克 90度熱水
總萃取時間2分30秒
取得 294克咖啡液
品嚐心得: 藍莓、樓桃、厚實圓潤、酸甜平衡，溫度下降到接近體溫時，圓潤滑順感強化，不澀不苦不酸，平衡好喝。
Ceramic filter
20g of ground coffee
Pouring 337g of 90℃ hot water
Total extraction time 2 minutes 30 seconds
Getting 294g of coffee liquid
Tasting experience: blueberry, peach, mellow, with a balance of sweet and acid. When the temperature drops to close to body temperature, the mellow and smooth feeling is strengthened, not astringent, not bitter or sour, balanced and delicious.
塑膠濾杯
以20克咖啡粉
注入 337克 90度熱水
總萃取時間2分30秒
取得 294克咖啡液
品嚐心得: 覆盆莓、酸感較突出，溫度下降到接近體溫時，酸感下降、甜感上升，但帶點澀感。
Plastic filter
20g of ground coffee
Pouring 337g of 90℃ hot water
Total extraction time 2 minutes 30 seconds
Getting 294g of coffee liquid
Tasting experience: raspberry, the acidity is more prominent. When the temperature drops to close to body temperature, the acidity decreases and the sweetness increases, but with a little astringency.
因此陶瓷濾杯具保溫性，可維持水溫下，對咖啡萃取較完整。當咖啡帶有豐富風味、甜度很高時，萃取出來的咖啡應該是酸甜平衡、風味飽滿好喝。也就是陶瓷濾杯呈現的結果。而塑膠濾杯較不具保溫性，較無法維持水溫下，咖啡的萃取較不完整，沒有將甜感、厚實度萃取出來，所以喝起來偏向酸感。由此可知，維持水溫對萃取咖啡的重要性，我們私心推廌使用「陶瓷濾杯」來沖咖啡，享受一杯風味飽滿、酸甜平衡、滑順厚實的好咖啡吧。
Ceramic filter has thermal insulation, which can maintain the water temperature and complete the coffee extraction. When the coffee has rich flavor and high sweetness, the extracted coffee should have a balance of sweet and sour, full flavor and delicious taste. That is, the result presented by the ceramic filter. The plastic filter cup is less heat-insulating and cannot maintain the water temperature. The extraction of coffee is less complete, and the sweetness and mellowness are not extracted, so the drink tends to be sour. From this, we can see that maintaining the water temperature is important for extracting coffee. We sincerely recommend the use of “ceramic filters” to brew coffee and enjoy a cup of good coffee with full flavor, balance of sweet and acid, smooth and mellow.
