As a novice barista, how to learn effectively? one way degassing valve tells you:
First, reading more books. Read the good books, and read the right books, it allows you to get a very comprehensive knowledge from the editor, and sometimes teachers have various reasons cannot be fully passed on knowledge to you, and the study of books to make up for teachers in the classroom did not talk about the issue .
Second, more communication. Now the network channel is very advanced, through the Internet channels such as WeChat, Zhihu, post bar, and website can get the corresponding knowledge. At the same time, some of activities under the line can narrow the distance between barista. Thus they can learn more about coffee knowledge.
Third, find qualified training institutions, the purpose is to allow everyone to quickly grasp the system knowledge, from theory to operation, and this is the effective channel for learning coffee. Cafes often at a dilemma situation, the employees will leave after they get coffee skills. There are also a lot of employees holding the "undercover" ideas enter into cafe, which makes the owner or predecessors are not willing to share their hard-won knowledge to them. The employment relationship may turn into competitive relationship at one day, and even new cafes are across the street. So the owner of coffee shop is not willing to teach too much coffee knowledge, but only teach the basic things of coffee, and they don't have to know other coffee knowledge. As the quickest and best way for a barista to know coffee knowledge, it really interferes with the way of baristas learn coffee knowledge.
