Qianjie-brief introduction of Coffee appreciation period

"Baking date"

The roasting date of coffee beans represents freshness, and beans baked within 2-3 days can be called fresh coffee beans. However, baking and buying is not actually the best time for beans, mixed with the smell of baked tobacco and the smell of beans themselves.

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. Of these, 35% were discharged in the first 3 days after baking. The carbon dioxide is then discharged with the same amount of 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.

"appreciation period" (Note: not a valid date)

Are you still looking at the expiration date on the package before you buy the coffee? We want to tell you another important thing: 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.

Is the flavor period of coffee beans 15 days?

From the experience of the baker, the taste period of coffee beans is about 15 days (specifically look at the baking degree), that is, after the bean cultivation period, 7-20 days from the baking date is regarded as the flavor period, that is, the taste period.

"bean cultivation period"

The process of waiting for taste is the so-called cultivation of beans (usually 3-4 days for single beans and 7-10 days for Italian beans), which is similar to the fact that red wine needs moderate oxidation to become smooth and layered after opening the bottle, but after being kept for a long time, the wine will turn sour again. Freshly fried coffee beans sometimes have grassy (peasy), which will disappear after the next night. On the other hand, new beans have a taste of baked bread, which those who insist on growing beans may not have tasted.

Knowledge expansion: after the shelf life of properly stored coffee, people will not have any problem drinking, flavorless coffee through sugar and milk can also become a good coffee drink.

In short: Qianjie is a coffee research hall, happy to share the knowledge about coffee with you, we share unreservedly just to make more friends fall in love with coffee, and there will be three low-discount coffee activities every month. The reason is that Qianjie wants to make more friends drink the best coffee at the lowest price, which has been Qianjie's tenet for 6 years!
