How To Roast Your Own Coffee Beans At Home

Home Coffee Roasting

Roasting coffee beans at home is the new trend among coffee lovers. With the day to day stress, there is nothing more relaxing that the aroma of a fresh cup of coffee at home. Roasting your own green coffee beans has lots of benefits; it’s inexpensive, you get fresh coffee, and finally, it’s very easy. So, how do you roast your own coffee beans at home?


Coffee Beans Roasting methods

There are different methods of roasting coffee beans at home. The type of method you choose depends on your budget, the amount of coffee you need, and your taste.


For many years, people have been roasting coffee beans using just a cast-iron skillet and campfire. This is how simple it can be. At home, you use your stove to roast the beans. You can also use an oven or a hot-air popcorn popper. All the three methods will produce great roasted coffee. However, if you want evenly roasted beans, then you may need to get a roaster.

2.Air roaster

This appliance is similar to the hot-air popcorn popper. The only difference is that an air roaster has a filter to collect the chaff from your beans. Some models also come with a smoke-control feature. The advantage of using this method is that you get evenly roasted beans in only 10-15 minutes. However, many air roasters feature small batch sizes, and therefore, you may need to roast your coffee daily, depending on your needs.


3.Drum roaster

If you really love coffee and want to roast large batches, a drum roaster is the tool you need. This tool is used by commercial roasters and independent coffee shops to keep up with demand. However, smaller designs are available for home use.


How to Roast Your Own Coffee Beans

1.Choose your beans

The grade or quality of green coffee beans significantly affects the taste of the coffee you produce. Go for a coffee that you already enjoy or research on something new that you want to try. The market offers a wide range of beans to choose from, but the most popular for home roasting include Tanzanian Peaberry, Ethiopian Yirgacheffe, Guatemalan Antigua, Brazilian Santos and Colombian Supremo. Keep in mind that all these beans are not created equal. For a healthier, finer and tastier home coffee, choose beans grown in healthier altitudes. Coffee grown in higher altitudes takes longer to grow and mature, and this allows the flavors to develop more fully. It also allows the beans to grow denser to enhance the complexity of their flavors.


2.Heat the beans

Regardless of the tool or machine you use, there are just a few basic rules to follow to properly roast your beans. If you are using a frying pan, pour the green beans into a frying pan. Turn the temperature up to a medium heat and keep on turning them over to avoid burning. If you’re using a roaster, pour the beans inside and turn on the heat.

As you start the roasting, don’t get your eyes off the beans. You will need to watch out for color change from green to yellow to light brown. Also, you will notice a difference in odors coming from the warming beans. It should be from a grassy scent to a toasty aroma. The first sign that your beans are starting to roast is the sound of the first crack, when the crease in the bean opens up to release trapped moisture.

3.Remove beans from heat

Some people stop after the first crack. But if you want a deeper flavor, then continue to roast. Basically, how long you roast your beans depend on your taste. There are 3 roast levels; Vienna or French toast, Full city and City. Each level has several graduations within it. The more you roast, the darker the bean.

City is the lightest roast and occurs after the first crack. This light brown stage is attained after around 8-10 minutes, when the temperature is at 370 degrees F. Flavors at this stage can be floral, malty or nutty, depending on the type of bean you chose. The second stage (full city) is attained when the temperature is nearly 400 degrees F. This gives you a deeper chocolate raspberry and is common among commercial beans. The last stage (French roast) will give very dark roasts. These beans are left in the roaster up to the second crack.


4.Store your beans

Store your beans in a loosely covered container and let them rest for 12-24 hours. This allows the flavor to develop as the green coffee beans release pent-up carbon dioxide. Your roasted beans will stay fresh for about a week, if stored in an airtight container, away from heat and moisture.
