Guide to Using Popcorn Popper for Roasting Coffee

It’s easy to order online or go into the market to buy a coffee roaster but only when you have extra bucks in your wallet. Here, you might wonder about ways to roast coffee in other roasters that you may have at home. You can also use Microwave oven in some way to roast the coffee beans but the most suitable option in this regard is using hot-air popcorn popper which is certainly highly inexpensive. Moreover, the popcorn popper stands as a winner in this microwave vs. stove top corn poppers competition because popper preserves most of the coffee’s taste and aroma. Nevertheless, converting this popcorn popper into a coffee roaster needs some work to be done.

Getting Prepared

  • Make sure that popcorn popper you are going to use for roasting coffee is capable for the job. Look for the best popcorn popper that would vents at the sides of popping chamber. Those vents are meant to pass heat into the chamber. The better way in this concern is to ask the representative at home center from where you are intending to buy popcorn popper.


  • There is a high chance that popper would not be ready for the coffee roasting job right away. If the lid of this popper is made of plastic, dispose it. Then enhance the chamber from top by attaching a food tin. That would increase the depth of chamber. You can use a sieve as a lid to cover the chamber.


  • Buy the green coffee beans that you would roast in the newly made coffee roaster. If you are facing difficulty in finding green coffee beans from nearby market, you can always search on the web and order online.


  • The aroma of coffee while it is being roasted is great. However, it can cause furniture with dense clothes to give strange odor which you might not find pleasant. Make sure that place where you are doing this job is properly ventilated.


Roasting the Coffee

  • To shorten and ease the process of coffee roasting, get the mix of green and roasted coffee beans. The ratio, by weight, between green beans and roasted beans should be 2:1 respectively.


  • Let the roaster get hot on the stove and then start pouring coffee beans in it. Observe the process and you will see beans’ natural sugar starting to caramelize. At this stage, the beans will start drying. After a couple of minutes, there will be cracks starting to appear in the beans. Roasting the beans further for 6 minutes will convert cracks into shades.


  • Get the filter removed from the top and check if the beans are properly roasted. You will certainly not be able to check beans by your hands while they are hot, so use the metal scoop to get some beans out of the chamber.


  • If the beans are not roasted up to the extent according to your desire, roast them further. Nevertheless, ensure that beans don’t start burning.


After the Beans are roasted

  • After the beans are roasted, cool them down as soon as possible. For that purpose, pour the beans into a colander and take it outside of the kitchen. Get another colander and pass the beans between both colanders for a couple of minutes. That should cool the beans down to room temperature. Never use water to cool the beans.


  • It’s more ideal to leave the beans for 24 hours in a tin with loosely adjusted lid upon it. That would help in the degassing of beans.
