咖啡豆也有保存期限嗎?Does Coffee Expire?
目錄:
1. 最佳賞味期-咖啡最好喝的時期
2. 保存期限-雖然香氣降低,但還安全可食用
咖啡豆是食物,也就代表他會變質,因此它有「保存期限」。不過,喝精品咖啡的人其實更重視的,是它的「最佳賞味期」;代表咖啡的香氣表現、風味層次最豐富的時期。
Coffee beans are food, which means they go bad, so they have a “shelf life.” However, people who drink specialty coffee actually pay more attention to its “best before date.” It represents the period when coffee's aroma performance and flavor levels are most abundant.
常見超市貨架上的咖啡豆,「保存期限」會設定約半年至一年;但販售新鮮烘焙的咖啡店家會告訴你,「最佳賞味期」約為1~2個月,為什麼呢?For coffee beans on supermarket shelves, the “shelf life” is set to be about half a year to one year; but coffee shops that sell freshly roasted coffee will tell you that the “best before date” is about 1 to 2 months. Why is that?
最佳賞味期-咖啡最好喝的時期
The Best Coffee Is to Drink Before the Best Before Date
新鮮烘焙的咖啡豆可維持其最佳風味約1~2個月。剛烘焙好的咖啡豆,內部會產生大量的二氧化碳及氣體,經過約3-5天的「養豆期」後,咖啡豆中蘊含的芳香物質,就會更完整且更容易被萃取出來;可以感受到明顯的花果香氣,香氣飽滿並具有層次。
Freshly roasted coffee beans maintain their best flavor for about 1-2 months. Freshly roasted coffee beans will generate a lot of carbon dioxide and gas inside. After about 3-5 days of “aging process,” the aromatic substances contained in coffee beans will be more complete and easier to be extracted. It has a distinct floral and fruity flavor and with a full and layered aroma.
在養豆後,到達風味的高點,接著咖啡的風味會逐漸遞減,超過1~2個月後氣體已排放差不多,也代表咖啡豆中大部分芳香物質已消散,只留下少許的芳香物質以及烘焙味,也就是這支咖啡的最佳賞味期結束。
After the aging process, the flavor reaches a high point, and then the flavor of the coffee will gradually decrease. After more than 1 to 2 months, the gas will be almost discharged, which means that most of the aromatic substances in the coffee beans have dissipated, leaving only a small amount of aromatic substances. As well as the roasted flavor, that is the end of the best tasting period for this coffee.
保存期限-雖然香氣降低,但還安全可食用
Shelf life - although the aroma is reduced, it is still safe to drink
過了最佳賞味期但還在保存期間的咖啡豆,雖然不像新鮮時那樣香氣飽滿豐富,但依然是可以安全飲用的狀態。因此除了參考豆袋上標示的保存期限之外,也要注意咖啡豆存放環境,不要放在高溫、潮濕、陽光直射等,會讓咖啡產生質變的地方。
Coffee beans that have passed the best tasting period but are still within the shelf life are still safe to drink, although they are not as full and rich in aroma as when they were fresh. Therefore, in addition to referring to the shelf life marked on the bean bag, you should also pay attention to the storage environment of the coffee beans, and please avoid places where high temperature, humidity, direct sunlight, etc. will affect the coffee’s quality.
咖啡豆有保存期限,但想喝到香氣飽滿豐富的精品咖啡,如果能購買新鮮烘焙的咖啡,才能自己掌握咖啡的最佳賞味期,從養豆開始感受每天咖啡風味的變化,掌控自己喜愛的最佳風味曲線。
Coffee beans have a shelf life, but if you want to drink specialty coffee with a full and rich aroma, if you can buy freshly roasted coffee, you can have the best tasting period of coffee. You can feel the daily changes in coffee flavor from the beginning of aging process and control your favorite coffee’s best flavor profile.
