According to the research of Dr. Lockhart and Ringo, a senior consultant of SCAA (American Fine Coffee Association), as far as coffee extraction is concerned, the dissolution rates of flavor molecules and hot water often vary according to molecular weight and polarity. Coincidentally, the low molecular weight sour aroma of flowers and fruits, as well as the taste of nuts and toast, as well as the cereal and rice and wheat flavors produced in the early stage of the Mena reaction will be excellent.

How to understand Coffee Baking Curve introduction to Starbucks Coffee Baking Curve

Coffee roasting curve with the rapid heating of coffee beans in the roasting process, water begins to escape from the bean surface and evaporate. The escape rate depends on temperature, bean quantity, bean density and air circulation, while the standard rate of a normal roaster is 5-7 minutes when the water content of coffee beans is reduced from 11% to 2%. Coffee beans at the initial stage of roasting sometimes turn a little white or milky white, and then
