認識咖啡的酸質評比 Understanding the Acidity of Coffee
目錄：
1. 「酸質」
2. 咖啡豆酸質小測試
咖啡的酸分成不酸、好酸、超酸嗎？NONONO~~精品咖啡的世界裡，酸有質地之分，從JC咖啡風味分數中所呈現的，9分並不是比8分酸，而是酸的質地比較好。
Is the acidity of coffee divided into non-acid, good acid, and super acid? No, no, and no. In the world of specialty coffee, acidity has different qualities. From the Justin Coffee flavor score, 9 points are not sourer than 8 points, but the acidity quality is better.
「酸質」
(Acidity)這是咖啡品質評鑑項目之一，要有較高的品質分數，喝下咖啡後要講得出是什麼水果的酸、而且又令人愉悅，像是柑橘酸明亮圓潤、葡萄柚酸質清新優雅、草莓酸明亮有層次等。
"Acidity" is one of the coffee quality evaluation items. To have a high quality score, you must tell the acidity is from which fruit and if it’s pleasant after drinking coffee. For example, it’s citrus acid and bright mellow, fresh and elegant grapefruit acid, or bright and structured strawberry acid.
JC咖啡會在每支豆子頁面上，附上風味分數說明圖，分數愈高、代表該項目的品質愈好；以酸質分數來說，9分比8分有著更明確的水果調性的酸質，而且酸質感受令人更愉悅。
Justin Coffee attaches an illustration of the flavor score on each coffee bean page. The higher the score, the better the quality of the item. In terms of acidity score, 9 points have a clearer fruit tone than 8 points and the acidity is more pleasing.
咖啡豆酸質小測試
以下列二支豆子來看，來自相同產地，只是產區稍微不同、批次不同，酸質分數不一樣：
The following two beans come from the same origin, but the production areas are slightly different, the batches are different, and the acidity scores are different:
▋ 衣索比亞 藝妓村 夏亞區 藝妓 日曬
風味：水蜜桃 莓果 高山紅茶 甜感飽滿
分數：香氣9、風味9、餘韻9、酸質9、甜感9、醇厚8
▋ Ethiopia Gesha Village Shaya Gori Gesha Natural-SINGLE-TERROIR
Flavor: peach, berry, high mountain black tea, full of sweetness
Score: aroma 9, flavor 9, aftertaste 9, acidity 9, sweetness 9, body 8
▋ 衣索比亞 藝妓村 班吉區 藝妓 日曬
風味：熱帶水果 葡萄 蜂蜜 乾淨滑順綿長
分數：香氣9、風味9、餘韻9、酸質8、甜感9、醇厚9
▋ Ethiopia Gesha Village Bangi Gori Gesha Natural-SINGLE-TERROIR
Flavor: tropical fruit, grape, honey, clean and smooth
Score: aroma 9, flavor 9, aftertaste 9, acidity 8, sweetness 9, body 9
夏亞區藝妓有著較佳的酸質分數，它的莓果酸質明確、明亮圓潤、令人感到愉悅；所以不是說班吉區藝妓的酸是比較不酸，而是同樣有莓果酸質，但班吉區的莓果調性沒這麼明確明亮。但班吉區的醇厚度分數就比夏亞區略高一點。
Geisha from Shaya Gori has a better acid score and it has well-defined berry acidity, bright, mellow, and pleasant. So it's not that the geisha in Bangi Gori is less sour, it has berries acidity as well, but not so clear and bright in berry tones. But Bangi's body score is slightly higher than Shaya's.
好的酸質有新鮮水果的特性，有足夠的甜感支撐，喝起來整杯咖啡層次感佳、風味豐富飽滿，是一杯令人陶醉的好咖啡！
Good acidity has the characteristics of fresh fruit and also enough sweetness to support it. The whole cup of coffee has a good structure, rich and full flavor, and it is a good cup of coffee!
