The so-called aged coffee beans (Aged bean) mean that raw beans age naturally by prolonging their storage time (usually 2murs-3 years). These changes include reduced acidity, color changes and thickening of beans. The storage environment must be cool and ventilated.

Properly stored coffee beans will change their taste and shape, such as reduced acidity, dark color and lack of moisture, thicker and thicker taste, sweetness with honey flavor, and some of the defects that originally belonged to raw beans become less obvious. Because the storage environment is dark and for a long time, old coffee beans are always difficult to get rid of the complex smell such as musty smell or commonly known as sacks or pigs.

Aged coffee beans (Aged bean) must be strictly and carefully controlled during storage, regularly flipped evenly, humidity and ventilation adjusted to prevent moth or mildew.

Generally speaking, the storage of aged coffee beans does not take place in the producing area or manor, but is the business behavior of raw bean dealers or brokers.

Aged coffee beans are different from Indian monsoon coffee, which is the result of natural aging through the rapid loss of water in raw beans during a short period of 3-4 months by exposure to the monsoon, which is young and strong. Old coffee beans are more different from old coffee. The flavor of raw coffee beans is preserved in the natural environment for about 12 months, and the weaker the flavor at the end is. The coffee beans that have been roasted for more than 12 months taste old and lack hierarchical changes, so they naturally lose the value of the products.

Not all coffee beans are suitable for storage as old coffee beans, and the raw beans that are usually selected for storage must have a strong physique. Therefore, the coffee beans produced in Indonesia's three important and well-known producing areas, Sumatra Mantenin, Sulawesi and Java, are the best choice for making aged coffee, especially the aged Mantenin. It is also an old coffee bean that is generally easy to buy in the world. The internationally renowned Hawaiian Kona also has a small number of aged coffee beans, but not many people know about it, mainly because it is not the mainstream flavor.

The aged coffee beans are full-bodied, calm, mellow and fermented, the taste is very similar to Pu'er tea, the warm and mellow colloid is smooth and smooth, and the aged coffee beans and Pu'er tea are delicate fermentation changes that have been brewing over the years. it's just that old coffee beans can't be stored as long as Pu'er tea, although there are great annual differences, coffee beans are fruits, Pu'er tea is leaves, there is still room for competition between the two.

Which kind of beans have better flavor and special performance, such as aged Mantenin, aged Sulawesi or aged Java? The flavor of the coffee made by the deliberate storage process is very similar, and if there is any difference, it is only the mellow performance produced by the healthy quality of the raw beans at that time; even the aged Hawaiian Kona made of high-quality materials such as Hawaii Kona can not retain the unique volcanic smoke smell of Extra Fancy Kona, which is enough to awaken the soul aroma, delicate and elegant acidity and clear and clean balanced taste. Some, apart from the honey taste, consistency, mellow texture and low acidity of the aged Indonesian coffee beans, they still can't overcome the complex flavors such as mildew, leather, sacks and cellars.

Qianjie coffee is recommended to brew aged coffee beans.

Recommend flannel

Step 1

The brand new flannel filter cloth must be removed, soaked in boiling water for 5 minutes, and then placed on the metal ring.

If it is a used filter cloth, it should be boiled in boiling water for at least 3 minutes.

Step 2

Grind beans while soaking the filter cloth. Because of the special material of the flannel filter cup, the flannel filter cloth uses a little more coffee beans by hand than when using filter paper, and the taste of the filter will be better. Of course, the right amount of coffee powder should be loaded according to the size of the filter cloth. 2 cups (240c.c. Use 40 grams of beans. It is recommended to grind the coffee beans into a thickness between white sugar and fine sugar.

Step 3

Dry the filter cloth, twist it by hand, and then put the filter cloth in the middle of a clean dry towel to absorb dry.

Step 4

Rinse with hot water, preheat the filter cloth and drip filter, and then pour out the water.

Step 5

Pour the coffee powder loosely into the filter cloth without special compaction.

Step 6

Using a wooden mixing spoon or cream knife, gently flip the coffee powder from the bottom up, and finally pull the bottom of the bag to adjust the shape.

Step 7

Make a hole about a coin wide and a thumbtack deep at the top of the coffee powder. This is because the powder layer is deep, so it is convenient for hot water to spread in all directions and moist coffee powder evenly.

Step 8

After setting and cooling the hot water to 85 degrees Celsius, start injecting water near the hole. It must be very slow at first, injecting 60 grams of water within 30 seconds. There is no need to soak all the coffee powder, capillarity will slowly spread the water. After the water injection is completed, wait for about 30 seconds.

Step 9

Start the second injection, this time faster than the first, with 140 grams of water in 60 seconds. At this time, the coffee will cause a large number of bubbles, which is a bit like the explosion of the universe in the movie. After the water injection is completed, wait 20 seconds, and the water level drops slightly.

Step 10

The last water injection, this time 120 grams of water in 30 seconds. The whole process takes 3 minutes to inject 320 grams of water. Because the filter cloth and coffee powder absorb about twice as much water as coffee powder, you can finally get about 240g of coffee, which is better than 1:6.

Using flannel filter bags to make coffee is time-consuming, so the temperature of the coffee is relatively low, and preheating the coffee cup can slightly increase the temperature of the coffee. But never reheat the coffee in any form.
