"is it the best time for coffee beans when they are freshly baked?"

-No!

The roasting date of coffee beans represents freshness ~ many friends will understand coffee bean roasting as cake baking and think that beans that are usually baked within 2-3 days can be called fresh coffee beans.

However, buying now is not actually the best time for beans to taste. According to Qianjie coffee's roasting experience over the years and cup test comparison, coffee beans that have just been roasted for 1-2 days are usually mixed with the smell of roasting smoke and the smell of beans themselves.

Why not drink freshly baked coffee beans right away?

Just baked ripe beans have a commonly known "dry feeling", the main performance is that the sour taste is more sharp, not round, sweet feeling has not reached a better state, some slightly astringent feeling hovering in the mouth. The baking process is a complex chemical and physical reaction process, as well as variables that we do not understand. But dryness is a real taste.

Each kilogram of coffee beans, in an unsaturated environment, emits about 6 to 10 liters of carbon dioxide, equivalent to 1% to 1.2% of the total weight of beans. 35% of them are discharged in the first 3 days after baking. Then carbon dioxide is discharged, followed by aromatic volatiles (volatile aromatics). Coffee beans will continue to emit nitrogen dioxide (exhaust) for about 48 hours after they are roasted, so the coffee beans will not taste good when they are cooked immediately.

What is coffee and beans?

Therefore, freshly roasted coffee beans usually need to be properly raised, that is, the time for coffee beans to emit carbon dioxide on their own.

Qianjie coffee is recommended to keep the beans sealed with a package with a single timing valve (to ensure that there is a place for carbon dioxide discharge, but also to block the entry of external air and oxygen), and leave it in a dry and cool place for 3-7 days. let the coffee beans release part of the carbon dioxide by themselves, take away the dryness, y make the coffee extraction more stable, and the coffee flavor will be more round and full.

Freshly roasted coffee beans raising time

Qianjie Coffee all coffee beans sold on the shelves are sent out within 5 days after baking and are packaged with a single exhaust valve to 100% guarantee the freshness of the beans. Only freshly roasted coffee beans will have more and richer flavor and aroma.

Different roasting degree of coffee beans, the period of raising beans will be different. Among the coffee beans sold in Qianjie Coffee, the recommended cultivation time is 3-4 days for medium-shallow roasted coffee beans, 4-5 days for medium-roasted coffee beans, and 6-7 days for medium-deep roasted coffee beans.

Taste period of freshly roasted coffee beans

The best taste period of coffee is not equal to the shelf life, you should pay attention to the baking time. Although the taste of roasted coffee beans will change over time in the next 1-2 weeks, we will usually taste the best in a week or so, although the taste will change over time and take an extra journey to witness the ups and downs of coffee.

From the experience of Qianjie coffee roasting, the taste period of coffee beans is about 15-30 days (depending on the baking degree), that is, after the bean cultivation period, it is the best taste period within 7-20 days from the baking date.

Is there an absolute "best flavor period" for freshly roasted coffee beans?

With regard to the "best flavor period", although the baking degree of each bean can be relatively stable, it still has an error of positive and negative degrees, even if it strictly follows the previous curve, which involves factors such as space environment. The days when you think it tastes good is the state that beans should have, that is, the "best flavor period".

After the taste period = stale beans, not only "go" the good taste, but also create a bad taste. The compounds in beans are affected by oxidation (oxidation) and the taste becomes negative. Therefore, it is recommended to buy about 2 to 4 weeks of coffee beans at a time and store them in a cool and dry place. It is also recommended that the flavor is the best when it is used at the end of 2-4 weeks. After the preservation period of coffee stored properly, people will generally drink no problem, if you feel sick, or quickly throw it away!

Shelf life of coffee and cooked beans

The shelf life of prepackaged food refers to the safe edible period of the product, which is provided by the producer and marked on the product for limited use. During the shelf life, the manufacturer of the product shall be responsible for the quality of the product in line with the relevant standards or the quality conditions expressly guaranteed, the seller can rest assured to sell these products, and consumers can use them safely.

Before establishing the shelf life of a kind of food, it is necessary to analyze the objective quality changes of food, such as microbiological test, physical and chemical test and sensory examination, and the microbiological index is often the most direct factor affecting human health. Coffee beans (powder) have a long shelf life because of their low humidity and are not easy to breed microorganisms. Generally speaking, the shelf life of coffee in aluminum foil bags is 12 months, while that of imported coffee is mostly 2 years.

The roasted beans sold in Qianjie Coffee are regularly sampled and sent to professional departments for inspection with a shelf life of 12 months.
