咖啡豆 怎麼保存呢?放冰箱可以嗎 How to store coffee bean? Can we put it in the fridge?

咖啡豆 要保持新鮮,又想買多一點、長時間保存,有什麼重點嗎?咖啡豆保持新鮮,要遠離三個地方,即遠離「氧氣」「濕氣」「陽光」。因此若咖啡豆袋上本身就有排氣閥,只要在使用過後,儘量擠出袋內多餘空氣,並把夾鏈封好,放置在陰涼乾燥處,就是對咖啡的良好照顧方式。

What can we do to keep coffee beans fresh, also buy more and keep them for a long time? To keep coffee beans fresh, we have to keep them away from three places, “oxygen,” “moisture” and “sunlight.” Therefore, if the coffee bean bag itself has an exhaust valve, as long as after opening, try to squeeze out the excess air in the bag, seal the clip, and place it in a cool and dry place, which is a good way to take care of the coffee.


放冰箱vs.濕氣

Store in fridge vs. moisture

 

若將咖啡豆放進冰箱再拿出,即使密封的再好,溫度的變化造成的凝水作用,易讓咖啡豆受潮而變質。烘焙好的咖啡豆,含水量很低,因此非常容易吸濕受潮而變質。

If you put the coffee beans in the refrigerator and then take them out, even if the seal is good, the condensation effect caused by the temperature change will easily cause the coffee beans to get wet and deteriorate. Roasted coffee beans have very low water content, so they are very susceptible to moisture and deterioration.


 為什麼放咖啡豆袋就可以保鮮

Why coffee bean bags can keep coffee fresh?

 

– 單向排氣閥 – 排放二氧化碳,阻隔氧氣進入

One-way exhaust valve – discharges carbon dioxide and blocks oxygen from entering

 

新鮮的咖啡豆烘焙好,會釋放二氧化碳,豆袋上的單向排氣閥,讓氣流只出、不進,所以可以讓新鮮咖啡釋放的二氧化碳排到袋外,而袋外的空氣進入不了。所以開封後的咖啡豆,只要把空氣擠出,夾鏈袋密封好,不要讓過多的空氣留在袋內造成氧化即可。

When fresh coffee beans are roasted, carbon dioxide will be released. The one-way exhaust valve on the bean bag allows the airflow to only go out and not in, so the carbon dioxide released by fresh coffee can be discharged out of the bag, but the air outside the bag cannot enter. Therefore, after opening the coffee beans, it is ok as long as the air is squeezed out, the zipper bag is well sealed, and do not let too much air remain in the bag to cause oxidation.

 

– 鋁箔包裝 – 避免陽光照射

Aluminium foil packaging – Protect from sunlight

 

陽光是咖啡豆的殺手之一,因為咖啡豆上具有油脂,陽光照射後,會造成油脂劣化,進而產生難聞的氣味。這也是為什麼JC咖啡的豆袋,選用可遮蔽光線的多層鋁箔袋。

Sunlight is one of the killers of coffee beans, because coffee beans have oils and fats. After being exposed to sunlight, the oils will deteriorate, resulting in unpleasant odors. That's why Justin Coffee's bean bags use multi-layer aluminum foil bags that block light.


開封後的保存期限是多久呢?

How long can we keep fresh after opening?

 

咖啡豆使用過後,儘量擠出袋內多餘空氣,並把夾鏈封好,放置在陰涼乾燥處,這樣的保存方式,期限是多久呢?

After the coffee beans are used, try to squeeze out the excess air in the bag, seal the zipper, and place it in a cool and dry place. How long can we keep it?

 

精品咖啡的愛好者們,通常是為了喝到咖啡的「好味道、香氣」。咖啡烘焙後產生的香味物質幾乎多屬於高揮發性的有機物,揮發到一定程度後咖啡豆就沒什麼風味了。因此咖啡豆的「賞味期」與一般食物的「保存期」大不相同,我們更在意的是還留存足夠風味的「賞味期」,因此一般來說,我們建議「賞味期限」在烘豆後儘快喝完,最好可以在一個月內,最多不要超過四個月,這也是為何標籤上的期限是寫四個月。雖然咖啡在烘焙過後含水率很低、水活性也低於0.6、微生物無法生長的狀態,即使放久也不會壞,但畢竟我們要品飲的是咖啡的風味,所以愈快飲用完畢愈好。

Fans of specialty coffee usually drink coffee for its “good taste and aroma.” Most of the aroma substances produced by coffee roasting are highly volatile organic compounds. After volatilization to a certain extent, the coffee beans have no flavor. Therefore, the “tasting period” of coffee beans is very different from the “storage period” of ordinary food. We are more concerned about the “tasting period” that retains enough flavor. Therefore, in general, we recommend that the “tasting period” is to drink it as soon as possible, preferably within a month, but no more than four months at most, which is why the period on the label says four months, after the beans are roasted. Although the water content of coffee after roasting is very low, the water activity is lower than 0.6, and the microorganisms cannot grow, even if it is left for a long time, it will not be bad, but after all, what we want to drink is the flavor of coffee, so the sooner we drink it, the better.
