How long can the shelf life of coffee be maintained? How much water does the ear-hanging coffee bag have to drink?

Recently, many people come to Qianjie coffee door to ask if they sell hanging-ear coffee. Qianjie usually replies, "there is no stock of hanging-ear coffee in the store. If necessary, it needs to be made on the spot!"

Many guests will be puzzled why the coffee shop does not even prepare a few hanging-ear coffee in advance and needs to be made now, so it is not as convenient as going to the supermarket container to buy.

The biggest enemy of delicious coffee is that the shelf life of time-hanging coffee is usually 12-18 months, but this period is only the time limit to ensure the quality and safety of food, not whether it tastes good or not. The real time limit that users care about is the taste period, which is particularly short in the field of coffee cooked beans (powder).

Qianjie made a series of comparison of hanging-ear coffee, after the coffee beans baked in 4 days were made into ears, according to the number of days on the baking date, there was no flavor after about 3 weeks (note: we are talking about flavor, aroma, sweet and bitter these flavors are still there), and anaerobic coffee can last longer and last about a month (do not rule out the "super standby" of individual coffee beans).

So, hanging-ear coffee can really make you drink a good cup of coffee in about 20 days. This is why Qianjie insists on no pre-storage of hanging-ear coffee, there is an order to make it again, and the specification of a bag is 10 small packets, so as to ensure that guests can drink up at the consumption of one pack a day during the appreciation period. Why is the appreciation period of hanging-ear coffee so short? This is about to talk about the production method of hanging-ear coffee, generally hanging-ear coffee needs to grind the coffee beans into coffee powder, and then put the coffee powder into the inner bag, heat-sealed, in the hanging-ear bag into the outer packing bag, heat-sealed. Such a small packet of hanging-ear coffee is finished.

The first reason for the short appreciation period is the pre-grinding of coffee powder. With the popularization of high-quality coffee, people gradually realize that freshly ground coffee has a great influence on flavor. After the coffee powder is ground into powder, the loss of carbon dioxide and flavor will be accelerated. Friends who have bought earbags can pay close attention to the fact that the earbags they have just got are flat and have no extra air, and after they have been placed for a few days, the outer bag bulges up, which is the loss of carbon dioxide and flavor.

Therefore, Qianjie will try its best to improve the speed and reduce the loss of flavor when making ears on the spot. And users should taste it as soon as possible when drinking it.
