How to roast coffee?

Must read

Coffee is one of the most popular drinks in the world, but how many people know how it’s made? Unlike tea or other popular beverages made from plants, coffee goes through several stages before becoming what you drink every morning. The roasting process for coffee beans has existed since early human history and has changed very little over time. Roasters use heat to bring out flavours and aromas that are otherwise undetectable by simply brewing even the best coffee beans in Brisbane offers.

Coffee is the most popular beverage in the world.

Coffee is a multi-billion dollar industry that’s getting more and more attention from enthusiasts. Coffee contains chemical compounds called antioxidants, which have been linked to reducing the risk of cancer, heart disease and other conditions. Coffee also has caffeine, which can improve mental focus by increasing dopamine levels in the brain.

The coffee plant produces coffee beans.

It’s essential first to know what they are and where they come from to understand how to roast coffee beans. Coffee beans are the coffee plant’s seeds, a perennial evergreen shrub or tree native to Ethiopia. A coffee plant produces cherry-type fruits that contain two seeds. 

The type of beans depends on their roast profile.

Even though you might find roasted coffee at your local grocery store, the most common type of coffee bean is unroasted. This means the beans haven’t been heated to change their colour and flavour yet.

Roasting is the process of heating raw coffee beans to make them darker in colour and to bring out their flavour. It can be done using a hand-crank machine or an automatic machine. But either way, it will result in roasted brown beans (aka “roast profile”).

These beans are sold to roasters for the final result.

Roasters are the intermediaries responsible for the coffee you drink daily. They buy green beans from farmers in Brisbane, who work hard to grow them and then transport them to processing plants where they’re cleaned, sorted and packaged. After that, roasters buy these beans in bulk (usually 50-pound bags) and roast them over a long period at extremely high temperatures, upwards of 500°F (260°C).

The process yields roasted coffee beans with varying degrees of brownness. Light roasted coffees have been heated for less time than dark roast coffees; medium roasts fall somewhere in between. Roasting itself is not a complicated process. The beans are placed in a large drum and then heated by gas jets until they have reached the desired colour. The longer you roast, the darker your beans become, as well as releasing more caffeine and oils. If you over-roast your coffee, it will lose its natural sweetness and complex flavours, making it taste burnt or bitter.

Roasting is an art.

It requires constant experimentation and new methods now and then to get an adequately roasted coffee. You can’t roast the same way every time. You have to experiment and find the best time for your beans. Many factors affect the roasting process, including the type of bean and size and weather conditions of Brisbane on a given day. It would be impossible to give one specific time for roasting everything because it depends on many things.
