Beans are usually roasted at about 230–260 degrees celsius. Coffee is kept moving during to roasting. When the inner temperature of the beans reaches 230 degrees celsius, the oil inside them begins to emerge. This changes the beans from green to brown and gives the coffee it’s actual aroma. Once roasting is complete, the beans are immediately cooled, either by air or water and now the coffee has to hurry to get to your cup.
