Coffee technology the three levels of coffee roasting
Level 1: basic roasting here refers to those who are familiar with the basic skills of roasting coffee beans and have the ability to bake raw coffee beans into commercially valuable coffee bean products. "Commercial value" means that you already have basic baking skills, and the roasted coffee beans can be accepted and recognized by the market. If you think you can bake coffee, but no one else is willing to spend money on the coffee beans you bake but yourself, then you belong to the player's leisure nature, not even the first level.
Level 2: adjust baking if you have already reached the first level and are able to target the taste, flavor and details of each coffee bean or each batch of coffee beans at will. If all aspects of characteristics and performance are optimized and adjusted in detail, then you already belong to the second level of "adjust roasting"! the coffee roaster at the "adjust roasting" level is familiar with the roasting machines he uses and how to add, highlight, weaken, or remove certain aspects of flavor performance without changing the baking degree.
Coffee roasters at the "adjust roasting" level have the ability to adjust the taste and perceptual elements of coffee beans at will, such as baking type, body thickness, front, middle and rear flavor, brightness, richness, sucrose sweet, caramel sweet, Roast Delta value, texture and touch, and are very familiar with the various sources and causes of salty, astringent and bitter taste, and know how to remove or avoid unwanted taste. Bakers who reach the "adjust baking" level can adjust and optimize the flavor of each batch of coffee beans according to the baking blueprint in mind and the requirements of customers.
The third level: art baking when you have reached the second level, moving to the third level of the higher level is the only way. Art baking is the reconciliation and combination of reason and sensibility, and all the baking skills you know are no longer the protagonist. Rich skills, knowledge and experience no longer occupy your head, coffee beans and baked flame is your canvas and brush, showing the real soul, is the outlook on life, is the dream, is the value.
