Many people who wish to roast their own coffee actually make the move to owning a coffee roaster. It is important to find a good roaster because with the perfect roast a cup of coffee can taste amazing. If the beans have been roasted too long, the coffee can taste burnt. The most important part about roasting beans is timing. It’s extremely important to keep an eye on the beans so that they do not burn and can be removed when they reach the perfect roast.

The perfect roast can be achieved through trial and error. After a while those new to roasting will be able to tell when their coffee beans have achieved the perfect roast.

There are two main types of roasters available on the market. Fluid bed roasters (also known as air roasters) are one type. The other type is drum roasters. Each type performs the basic function of roasting the beans, but it’s important for those looking to buy a roaster to understand the different ways in which the two types of roasters. Regardless of the type of roaster chosen, roasting coffee at home can save money and give way to better tasting coffee.

There are over 800 different compounds in coffee beans. These compounds contribute heavily to the flavor of the bean. Often other flavors are added to the bean to make it more appealing. These flavors are usually added after the beans are roasted, but before the coffee is ground.

The characteristic flavor of coffee comes from roasting. Coffee beans are actually green before they are roasting. Roasting causes the green bean to expand and change color, flavor, scent, and since the roasting gets rid of moisture in the bean, the density also changes. As a bean is roasted it goes from a pale green color to yellow, where it makes a gradual change into shades of brown. The roasting of the beans changes the flavor. The flavor from a bean that has roasted for longer amounts of time usually taste so different from when it is fresh that even many coffee connoisseurs are unable to tell which kind of bean it was.

Roasting coffee is actually a chemical process. In this process, the flavor of the bean is altered so much that it augments the flavor. Beans that been roasted in such a way that the sweetness and aroma are maximized and the bitterness and acidity are minimized are highly desirable for espresso. Beans contain sucrose. As the sucrose is roasted, the bean darkens. This is because of the caramelization process as sucrose is sugar. When the temperature of the beans in the roaster reach temperatures of between 170-200°C, this is the moment when the sugars caramelize and bring out the wonderful flavor of the coffee.

Those who are more experienced or want to become more experienced, should invest in a drum roaster. A drum roaster is popular because there is a viewing window which allows those roasting the beans to watch the progress. It is also important for those buying a new roaster to consider the size of the roaster. The roaster should allow for enough space in the owner’s kitchen for other appliances. The perfect roaster will be small and allow precise roasting times and temperature that the owner can control.

When shopping for a roaster it’s a good idea to understand how the potential purchase operates, what quality roast it offers, and how much work is required in the usage and maintenance of the machine. There are many different types of roasters. An air roaster roasts beans with a hot stream of air which is why it is one of the more popular methods. A drum roaster is highly popular, but those using these must pay attention during the roasting process.

Home coffee roasters come in two types and these are fluid bed roasters and drum roasters. Fluid bed roasters are so similar to air popcorn poppers, that an air popcorn popper may be used in a pinch. These roasters take approximately 7-20 minutes to roast depending on the roaster, the bean, and the desired darkness. These roasters are easy to clean an maintain. A drum roaster is simply an oven in the shape of  a drum with a viewing window.

The beans should also be wholly intact. Beans that have been broken or are bruised do not make for a good roast as they will quickly lose the flavor oils during the roast. Green coffee beans should smell good and look healthy. They will also taste good.

Kenya AA and Costa Rican are perhaps the most popular green coffee beans used for home roasting. Those shopping for beans should also consider how many beans they would like to buy.

Master coffee roasters are in demand because of the personalization they can bring to any coffee house or coffee producer. A coffee house with their own master roaster will be able to be accountable for their own quality control instead of relying on a supplier. The in-house master coffee roaster will also be able to tell customers the roast level, the blend, and the origin of each type of coffee available in the coffee house.

A master coffee roaster also can roast the coffee as needed so the coffee house management doesn’t have to worry about ordering, stocking, and rotating stock.

While there is no real certificate in coffee roasting that makes a person a master coffee roaster, the roaster’s guild is currently setting criteria so that those who pursue careers in this path can actually be certified if they meet certain criteria. Much of this criteria consists of the student’s ability in sourcing and sampling coffee. Students will also be require to determine the best roast profile for certain beans and be able to roast it. These students will be required to do this consistently before obtaining certification.

Some roasters come with a built in thermometer which allows those roasting beans to keep track of the temperature inside the roaster. When beans are roasted they will turn from green to yellow and will finish at brown. This is because of the caramelization process that the sugars in the beans go through when being roasted.

Pre-roasted coffee is brown whereas fresh coffee beans will be green. It’s a good idea to roast the beans until they turn brown. The natural oils in the coffee beans will come out in the roasting process so the beans will also be covered with oil. Those roasting the beans will notice a strong coffee smell in the air and will hear cracking sounds as the roasting of the beans nears the finish. It’s a good idea not to use the beans right away, but wait about 12 hours after the roast for the best flavor.

Roasting coffee beans is actually fairly simple and only takes a few minutes to do. Coffee beans only take about 10-20 minutes to roast to the beautiful coffee brown color. Those roasting coffee will start to notice familiar coffee smells as the coffee roasting process is near its finish. Once the natural oils start coming out of the beans, they are finished.

After they are removed from the roaster and cooled, it’s a good idea to remove any excess oil from the beans before grinding them. Roasting coffee is the perfect way to get the best tasting coffee. It is also a great way to personalize the flavor so that coffee drinkers can get the flavor they love.
