A closer Look at Coffee Beans
Coffee beans trace their origin to warm climates, primarily those located on or close to the equator. This "Goldilocks zone," where growing conditions are just right in terms of temperature, sunlight and rainfall, is widely nicknamed the "Bean Belt." The beans themselves are found green, and only begin to resemble the coffee beans we know and love are a roasting process. When coffee beans are roasted, moisture is removed and a chemical shift occurs within the beans themselves. This leads to the development of the java smell and the classic flavor notes that coffee-lovers the world over have come to adore. Roasting must be conducted quickly, both in terms of heating and then cooling, to attain optimal results with regard to flavor and aroma.
How to Roast Coffee Beans
In a basic sense, coffee beans are roasted using high levels of heat - anywhere from 180 to 250 degrees, and sometimes higher, produces the desired effect. Of course, as with heating other forms of food and drink, there are different strategies for the coffee-bean roasting process.
Manually: If you want to get back to basics and roast your beans by hand at home, all you will need is a device that can generate heat - think a frying pan, wok, stove-top popcorn maker or oven. This method can be effective although it tends to be slower than using an automated coffee-roasting machine.
Automated machines: There are products available on the market designed specifically for roasting coffee beans, and they typically fall into one of two categories: air roasters and drum roasters. The former method involves extremely hot - you guessed it - air, to roast the beans. The later involves a special rotating cylinder, into which the beans are poured and then heated. The rotation can be powered via different methods, contingent on the design of the machine in use.
Before you start roasting, however, it is important to be aware that roasting medium and dark profiles can actually lead to the creation of a lot of smoke, so be sure to crack a window or two before you start!
