Shelf life of roasted coffee beans-how long can baked beans last?
Shelf life of roasted coffee beans-how long can baked beans last?
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 oil performance of coffee is mainly related to temperature and baking degree. Generally speaking, the shallower the roasting degree, the less oil on the bean surface after roasting. The deeper the roasting degree, the more oil the beans will show. In the same way, it is the same with temperature. If the temperature is low, the speed of oil production on the surface of beans will be slow, while when the temperature is high, the speed of oil production will be accelerated.
After the coffee beans are roasted, it takes about 1-3 days to raise the beans, in order to give full play to the various flavors of the coffee. The grown coffee beans should be specially preserved. I recommend you to use special sealed cans for preservation. The top flavor of coffee beans can only be maintained for 3 weeks to a month at most, and then it begins to lose a lot. If the coffee is ground into powder, the best flavor will be lost within a week, so friends who can afford to buy coffee mill are advised to buy fresh coffee beans and drink them fresh. So when buying coffee, the baking date is a very important reference condition.
About temperature: high temperature will cause coffee to produce oil, increasing the chance and degree of flavor oil being oxidized by air. So friends sometimes put coffee in the refrigerator, just like keeping tea. Here I just want to say that friends in the north please put the coffee beans away from the heating as far as possible in winter. It's OK to consider putting it in the refrigerator, but check to see if it's sealed and put in the refrigerator, otherwise your coffee will become a deodorant in the refrigerator.

A brief introduction to the description of the flavor of coffee beans treated by half-sun treatment the pre-treatment method of half-sun treatment is almost the same as the water washing method, first put the coffee fruit into a large water tank to remove the floating fruit, and then put the sunken fruit into the pulp screening machine to remove the pulp. Through the above steps, not only the immature fruit can be better removed, but also, more importantly, the coffee can be removed.

The best drinking time of coffee beans after roasting
The debate about the best drinking time for coffee beans after roasting-the best drinking time for deep roasting and light roasting, I think will last forever, because the choice of the roasting degree of coffee marks the roaster's understanding of the flavor of coffee. Uncle Dou personally believes that deep roasting and light roasting do not need and should not be unified across the board. Bakers' understanding of coffee is based on this.
