Commercial green coffee beans, after roasting, become cooked coffee beans (roasted beans), produce unique color, aroma, taste. The size and duration of roasting determine the flavor of coffee. The longer the roasting time, the darker the color of the coffee beans, and the taste changes with the length of roasting time. Light baking tastes sour, dark baking tastes bitter. To make your favorite flavor, you must start by roasting coffee beans.

The whole baking process can be roughly divided into four stages:

1. Steaming stage: 00 -10min; Xiadou-140 ℃; This is the most important process of coffee bean endothermic reaction. At this stage, beans will slowly expand, and the color will change from green to white. Water will slowly evaporate from the bean center because of the heat absorption of beans. Coffee tastes good or bad depends on this stage. When the water evaporates too fast, it is easy to cause the bean heart to be unripe, and the beans are easy to be bitter. When the water evaporates too slowly, it will cause the coffee taste to be dull and the aroma is not rich. Therefore, we insist that the steaming process must not be omitted. And use this process to make coffee more aromatic, stronger, and tastier.

2. Dehydration stage (before explosion): 10 - 15min; 140 -180℃; When the end of steam culture, coffee beans will be white, quickly converted to light brown, coffee beans will continue to absorb heat to reach a explosion, coffee beans will be steamed by the expansion, into a reduction of dehydration, then the moisture of coffee beans will rapidly decrease, when the absorption of heat reaches the coffee itself when the extreme, there will be an explosion reaction, which is called a explosion.

3. 15 - 18 min; 180 -210℃; After the explosion begins, the coffee beans will begin to give back the "just right heat" you gave it, showing a perfect exothermic reaction, then we can obviously smell that the aroma of coffee will change from grass flavor to coffee coke flavor, and as the explosion proceeds, the coffee beans will also explode and expand, at this time, it will start to burn, basically the coffee can be drunk, there will be no grass flavor, but the coffee at the beginning of the explosion will be very sour, not bitter, as time goes on, Coffee taste will be converted into non-acid, extremely bitter, generally speaking, the next bean point will be determined by the flavor of the coffee itself, when the sour taste is fast disappearing, bitter taste is fast appearing, usually this will be the next bean point, then the coffee sweetness of the next bean will reach the peak, the aroma will also be optimized, this point depends on the coffee itself "flavor", due to the growth environment, climate, soil, moisture difference, coffee "flavor" will be slightly different, check in this link, Keep this point in our SOP and keep it stable.

4. Second explosion stage: 18 -20min; 210-lower beans; After the first burst, coffee beans will slowly mature, emitting a charming aroma, and when the heat absorption reaches the second vertex again, coffee beans will have a second explosion, is the so-called second explosion, in the skin of the heart, will open a space, carbon dioxide in coffee beans will continue to discharge, causing internal temperature continues to rise, began to coke, into oil, ooze coffee surface, coffee flavor will be bitter, rich flavor, Starbucks is usually roasted to this stage, and then continue, coffee beans will slowly turn into coke, in addition to bitterness without any flavor, such coffee is no life, this is a perfect performance of coffee beans.

After these stages, the delicious and charming coffee is 90% complete, and all that remains is to brew the perfect flavor.
