Since the process of making coffee is a combination of numerous variables, numerous trials and errors are followed to obtain a certain result. Among them, roasting, which determines the flavor of coffee by roasting green beans, is one of the most difficult processes to predict the outcome.

Not only does the taste change through the moment when the temperature changes, but the green beans can also burn black in a matter of seconds.

In fact, it is not easy to do this roasting in your home cafe. Of course, home roasting is possible with a simple device, so it is not difficult to try. 

Things You Have To Follow After Purchasing Green Beans

In many cases, from the process of harvesting sacking the green beans, the defect beans or some other substances are being together. Especially, if the price of green beans is cheap, then you will face this problem more often.

So, now it is your responsibility as a roaster to pick out those substances by your hands. If you pass this process, then it will badly affect your coffee taste and aroma. Therefore, you’d better pick them out before you roast the green beans.  

5-Proven Methods To Roast Coffee Beans At Home – Coffee Roaster Alternatives

1. Home Roasting Using Strainers

 1. Home Roasting Using Strainers

Strainer roasting is a direct fire-roasting method in which green beans are roasted directly in the fire. And you can easily see the change of green beans with your eyes and nose. Also, you can feel the wild taste and aroma of raw beans. 

Depending on the size of the strainer, the amount of green beans to be input is different as well. For a strainer with a diameter of 13 cm, about 20 to 40 g of green beans is suitable. But if a large amount is added compared to the size, the roasting is not evenly done, so it is easy to produce a mottled result.

The larger the strainer, the greater the number of green beans that can be input. Weight also increases. If you add constant agitation activity to this, it can be overwhelming on your shoulders and wrists. Therefore, it is better to start with a small size rather than choose a large net from the beginning.


  • Put the right amount of green beans depending on the strainer size.
  • Turn on the gas stove, shake the strainer at around 40 to 50 cm high.
  • It takes around 2 to 5 minutes to take the moisture away. (might have some difference depending on the fire level)
  • When the moisture almost finises, the surface color of the bean turns yellow and has a smell of wet grass.
  • After all the moisture compeltely finsihes, then it is time to heat the beans deeply. Here, lower the strainer up to 20 to 30 cm from the fire and at the same time start mixing the beans.
  • A few moments later, you will hear the pat pat sound, and we call it the first crack. When you hear a strong pat pat sound, then you can turn the gas down and lower the strainer up to 10 cm from the fire. 
  • Now, you can decide the time to turn the coffee beans out. Normally, the beans for drip coffee roast one more minute after the first crack.
  • However, if you want dark roasting, you can go for the second crack, but be careful from burning. 

2. Home Roasting Using Frying Pan

Frying pans are familiar kitchen utensils owned by more than one at home and are also traditional roasting utensils that have been used for a long time.

Experts recommend to purchase a frying pan separately as coffee roaster rather than using the one at home. There are no specific frying pans for roasting, but a pan with a certain depth is easier to roast. This is because space is in need so that the green beans can be evenly mixed during stirring.

The size should be 20 cm in diameter and 7-8 cm in depth. A pan with a lid is good, but if you don’t have it, you can easily replace it with a lid of the same size. It seems that you can see the change of green beans without opening the lid made of tempered glass. However, it becomes useless because the silver skin and coffee oil get tangled and stick to the inside of the glass. Above all, it is not a recommendation because it weighs quite a bit.


  • Close the lid of a frying pan and preheat for around 1 or 2 minutes over high heat.
  • Can roast around 200mg to 250mg at one time.
  • Open the lid and heat for 2 to 3 minutes, at the same time, mix and stir the green beans well.
  • Watch and check the change of the green beans and heat them evenly. Must wear gloves to avoid the burn.
  • After the heating starts, to turn the inside heat up, close the lid and lower the heat a bit up to 150 to 160 degrees.
  • When you mix the beans, it is important to stir the beans evenly by grabbing the handles.
  • When the first crack starts, reduce the heat to low and open the lid to lower the heat.
  • Then it is the end of the process of roasting coffee beans with a frying pan.
