Fresh roasted coffee is every coffee drinkers dream. Not every coffee drinker understands the process of how coffee is made, including the roasting process. To understand it a little better lets go through the basics.
Processing
A good coffee always starts with a good bean. This is where coffee starts to differentiate as far as brands are concerned. Some places use processors that will was the beans to remove the fruit of the bean and separate out the different densities of beans. Less dense beans will float to the top where they can be easily removed. Some use a slow dry process. Dry processed beans have a subtle acidity compared to the higher acidity of wet processed beans. The acidity level is what gives coffee its flavor. Without acidity it tastes flat. An important factor of good processing is that it should leave the bean with a good moisture content so that the flavors can develop in the roasting process.
Roasting
Roasting allows the beans to produce levels of acid, aroma and other flavors. The first stage of roasting turns a green bean into a yellow color and creates a smell similar to popcorn. When the next stage is reached, at 338F-392F, the sugar in the beans starts to caramelize. It is important that the sugars caramelize or the coffee will be too sweet once brewed. At 400F the next stage begins and the beans double in size and lighten in weight. The temperature will rise to 428F the bean reduce further in weight and release CO2. At 446F the beans become oily and there is usually a pop sound. This is a critical stage where the beans can be over roasted if the roaster is not careful. The oils and aroma start to boil off and combine with air if this is overdone then the beans will lose flavor and take on a burnt taste. Achieving a balance of bitterness, acidity and other characteristics is the goal in this final stage.
The Perfect Taste
Tasting guides will often use the term body to describe the kinds of proteins and fibers in the final brew of coffee. It refers to how the brew tastes on the roof of the mouth. It is determined by the roasting process. Too light of a roast will be too bitter, while too dark of a roast will take on the aforementioned burnt taste. Neither is considered the perfect roast. It should fall somewhere in the middle with a good balance. The type and brand of espresso maker can make a difference as well.

How To Make Your Own Roasted Coffee Beans
Coffee is one of the most drank beverages in the entire world. It is among the top five beverages that people drink daily. We get the coffee beverage as a result from grinding roasted coffee beans and then processing the coffee grounds with water to create the divine drink that we have now. Roasted coffee beans are the result of an art form of roasting.
Roasting Your Own Beans
Roasted coffee beans are achieved by exposing the green coffee beans to heat and waiting for the sugars in the beans to come out. The first step to having your very own roasted coffee beans is to pick the beans that you wish to home roast. There are actually just a few kinds of coffee that are quite popular. Arabica is one of the most highly utilized coffees because of the flavor.
After choosing the beans that you wish to make roasted coffee beans with, you have the option of choosing when to roast your beans and how many to roast. You can actually roast the whole lot and then store the roasted coffee beans somewhere cool and dry. Do not grind them all at once because grinding the coffee releases the natural flavors. It is better to grind them in batches for your brewing pleasure because freshly ground beans have more flavor compared to those which have already been ground and stored.
To make tour own roasted coffee beans, pick an appropriately sized pan for roasting the beans. Make sure that there is still some space left for turning the beans for an even roasting. Unevenly roasted coffee beans will create a weird flavor of green, unroasted beans and fully roasted beans. Turn on the heat at low to medium and start to continuously move the coffee beans around the pan to promote even cooking or roasting.
At around 15 minutes, your roasted coffee beans will have a glazed or greasy look. This is because of the oils and sugars that have been released by the exposure to heat. The roasted coffee beans can no be safely transferred to a flat surface covered with tissue to absorb any excess oils or moisture. When the roasted coffee beans are cool enough to touch, you can place them in an airtight container for storage although some people don’t mind if their roasted coffee beans are exposed to the air. This is because the flavor is locked in due to the roasting. The process of grinding the coffee beans will release the flavor and make it ready for brewing.
