Boutique Coffee Science explains the life of coffee beans in detail

Food has its shelf life, coffee beans generally have a shelf life of one year, but for those who pursue high-quality coffee, just quality is obviously not enough, so how long is the life cycle of coffee bean flavor? Is the coffee bean as fresh as possible? Friends who like red wine all know that good red wine needs to be opened an hour in advance to oxidize the red wine, which will be more conducive to the release of aroma. Although the principle is different, coffee does have a similar practice, which we call bean cultivation.

Like other topics of coffee, the theory of raising beans is also divided in the coffee industry, and there is no final conclusion. As the so-called opinions vary, I can only talk about it in combination with my own personal experience.

The freshly baked coffee is full of vitality, reflected in the coffee extract, that is, the soy gas is so abundant that it expands at the slightest encounter with water.

Because the coffee is too active at this time, the fat will be rougher when making Espresso and will dissipate quickly. When using hand flushing or other utensils to extract, the flavor is bright but not mellow, and its sour taste is often too sharp, just like people in childhood, active, simple but emotionally unstable, and not calm enough, so you need to raise beans at this time.

I dare not judge which is right or wrong, but I personally prefer the latter, that is, freshly baked beans need to maintain proper contact with the air for a certain period of time.

The duration of bean cultivation depends more on the baking degree and extraction method. Coffee that is lightly roasted and extracted with utensils is generally raised for 1 to 3 days, while those that are deeply roasted and extracted with Italian coffee beans need to be raised for 3 to 5 days.

Young adults-- when drinking

Good coffee beans should be sealed and preserved as soon as possible. It is said that beauty is easy to grow old, and so are coffee beans. The peak stage of coffee bean flavor usually lasts only 2-3 weeks, no more than 1 month at most, so we can also think that the shelf life of coffee beans is 1 month. Of course, aging can be properly delayed by some man-made means, such as filling inert gas, but the laws of nature cannot be reversed by manpower after all.

The period of decline-- the late twilight of heroes

Which will be more attractive, a former beauty in her seventies and eighties or a cardamom girl in 2008? The flavor and aroma performance of a top coffee in recession may not be as good as that of ordinary coffee in its prime. Therefore, in the selection and purchase of coffee beans, not only depends on the brand and variety, the production date is a very important parameter.

How to judge the period of coffee may need to write a few more articles to make it clear, but in any case, we should remember that the freshness of coffee beans is very important, when drinking coffee, we can not only recognize the brand. This is exactly what Starbucks in China has been criticized by industry insiders.
