Coffee roasting concept the roasting method of professional coffee is usually divided into eight stages of urban roasting

Coffee roasting

Raw coffee beans themselves do not have any aroma of coffee, only after fried, can you smell the strong aroma of coffee.

If the coffee is not roasted well, even if the raw coffee beans are very good, you can't get good ripe coffee beans; as a result, you can't make good coffee. Only with good coffee raw beans, after proper roasting, is it possible to process good coffee cooked beans, and it is also possible to provide a good prerequisite for making good coffee.

Fried coffee beans are roasted at high temperatures, or roasted, to create the coffee's unique color (similar to amber, depending on the degree of roasting), flavor and aroma. Frying turns the green (or yellowish) raw coffee beans into the familiar tea-brown coffee beans. High-quality fried roasting refers to the ingenious expression of the aroma, sour and bitter ingredients of raw coffee beans.
