When can you drink coffee beans after baking? how many days is the best shelf life?

Introduction to coffee roasting

1. Deep baking will make guests who don't know much about coffee feel very coffee-flavored.

(the coffee beans I use in my own shop are lightly roasted and sometimes complain, "Why aren't they all bitter / too light?")

2. The requirements for raw coffee beans are reduced, and it is not even necessary to carefully select several kinds of coffee beans that can complement each other. The flavor of coffee produced by deep roasting of any kind of coffee beans is similar, because deep roasting will burn off most of the flavor of coffee beans.

3, low requirements for coffee machine operators, can almost ignore human factors and make a stable coffee (because you want to use this coffee bean to make a unique flavor is very difficult);

4. The taste of deep-roasted coffee beans changing with time is basically undetected, so it is convenient to store for a long time.

The roaster is getting closer and closer to mass consumers. At the request of consumers, more and more stores will show the baking operation to everyone. On the one hand, it does not take time to do so, on the other hand, watching your choice of raw beans colored a little during the baking process can also bring a strong sense of visual satisfaction to consumers. On the market, both roasters for consumers and small roasters for families are hot air models. Although this kind of roaster does not bring much change to the coffee industry, they can bring the coffee industry closer to consumers. It was not until the 20th century that the baking industry developed. In order to improve production efficiency, it is not only necessary to increase the amount of baking at a time, but also to shorten the time for a single baking, so the model that directly heats the baking room (where the coffee beans are put) is inefficient. This type of machine is easy to scorch or bake unevenly if it has too much firepower. In order to solve this problem, someone invented the hot air roaster, which can keep the heat source away from the baking chamber, which not only solves the problem of uneven coke burning and baking, but also widens the baking speed. Soon after that, a roaster with higher thermal efficiency was invented.
