The traditional Kopi Luwak is a folk culture of the local coffee industry in Indonesia.

After eating the coffee beans, the civets complete the fermentation in the stomach, destroying the protein of the coffee beans, producing short peptides and more free amino acids, reducing the bitterness of the coffee. Because the coffee beans cannot be digested, the civets excrete them, and after washing and baking, they become civet coffee.

Although coffee beans are not digested in the civets' digestive tract, strong corrosive digestive juices have corroded its surface. there is a special protease in these digestive juices, which can break down the original protein chain of coffee beans. the long-chain structure of proteins are broken down into small particles to form short-chain peptides, and there is also a by-product-amino acids. In addition, masked palm civet in the excretion of coffee beans, feces will pass through the nearby reproductive organs, coffee beans thus stained with musk oil secreted by reproductive organs, and will have a unique musk smell. ?

The company M.P. Mountanos, which first introduced Kopi Luwak coffee to the United States, pointed out that at first, when I heard about this kind of coffee fermented in the body, I thought it was a joke in the industry, but I didn't take it seriously. later, I saw a special report on Kopi Luwak in National Geographic Magazine and became interested in her. it took seven years to find a stable source of supply and began to introduce a small amount to the United States.

Generally speaking, Indonesian coffee has the taste of earth and traditional Chinese medicine, and its consistency is the highest in all continents, but Kopi Luwak has a stronger tussle and consistency, which is almost close to syrup, and its flavor is very special. if you don't like Indonesian coffee in the first place, you must hate Kopi Luwak even more. If you prefer the fishy smell of aged beans, you may love this alternative coffee.

Experts who have tasted Kopi Luwak have put forward a polarized evaluation, and some people compare it to the best coffee in the world. Although it is the best, but whether you are willing to spend thousands of yuan to drink a cup of Kopi Luwak is your personal preference. ?

First of all, we need to distinguish between shelf life and shelf life. The shelf life is the time when the coffee bean / powder itself does not deteriorate (it will not break your stomach), while the shelf life is the time when the unique flavor of coffee is not exhausted. The shelf life is usually much longer than the shelf life, because the aroma of coffee is easy to pass away and the shelf life is relatively short. So, a simple understanding of the difference between shelf life and shelf life, is the difference between ordinary coffee and good coffee.

Secondly, the shelf life of coffee is different in different states, taking coffee beans, coffee powder (mainly tin foil packaging) and hanging-ear coffee (single bag coffee powder package) as examples.

Coffee beans

Generally speaking, coffee beans are much easier to retain aroma ingredients than coffee powder. Usually, coffee beans packaged by one-way valves can be stored for 18 months, but the shelf life of bagged coffee beans of different brands varies slightly due to the processing (roasting) scale of the origin and the geographical location of the manufacturer. And there are also a lot of small private custom coffee beans on the market, this type of coffee beans, you can learn more about the baking hardware conditions with the seller, and guide yourself to determine the use time and purchase quantity. Usually, the coffee beans baked by roasters with the capacity below 30KG had better be used up within a month, because the fat components of coffee beans will be oxidized, when found to emit the taste of cooking oil sour rot or soot. It's best not to use it.

To identify whether coffee beans are out of date, you can refer to the following characteristics:

-feature 1: the appearance of coffee beans becomes very black (rather than dark brown), or mixed with a little wet feeling

-feature 2: the taste is very bitter (because black vermicin accumulates too much, there will be an abnormal bitterness)

Feature 3: it looks yellow on the outside (mostly moldy, when the inside of the coffee bean is moldy and breeds bacteria, it will cause the appearance to produce chemistry and turn into a yellow shell)

How to save it?

1. Keep in a dry place.

2. Using sealed containers or sealed packaging, the best way of preservation is to use tin cans, that is, to use cans for preservation.

3. It is best to store the coffee beans at room temperature of 10-20 °. Do not put the coffee beans in the refrigerator after opening. Fold the mouth of the bag first, tighten it with the shelf, and store the coffee beans in a dry and cool place.

4, do not use the coffee beans, use a coffee spoon to scoop out the package, lose as little as possible the safe carbon dioxide gas in the bag, and slow down the oxidation rate.
