How to Roast Green Coffee Beans at Home Overview
Learning how to roast green coffee beans at home is a great way to elevate your coffee experience and take things to the next level. When you take direct control over the roasting process, rather than relying on someone to do it for you, you’re able to exert far more control over the flavor you ultimately get out of the beans. It’s a bit of work, to be sure, but it’s also fascinating and a lot of fun.
As we mentioned above, the easiest and best way to roast your own beans is to buy an appliance dedicated to the task, like this one: Behmor 1600 Coffee Roaster.
There are, of course, numerous models to choose from, but this one gets consistently high marks for being user-friendly and producing stellar results.
Unfortunately, not everyone’s budget will allow for extravagances like these. If you can’t afford a dedicated roasting machine in your kitchen, but still want to try your hand at it, you’re in luck, and we’ll spend the rest of this piece exploring alternatives you can try, using the stuff you’ve probably already got in your kitchen.
If that sounds good to you, let’s get right to it!
Important note about roasting in general:
This applies to whatever roasting method you ultimately choose. Remember that coffee beans will continue to roast for a brief period after you stop the roasting process and remove them from the heat, so get in the habit of stopping slightly before the beans reach the color you’re looking for (golden brown for light roast, medium brown for medium roast, or dark brown for dark roast).
The Air Popper Method
Almost everyone has an air popcorn popper lying around in the kitchen or collecting dust somewhere in the garage. If you don’t, you can often find them at thrift stores for under ten bucks.
That’s good because using them in this manner would void your warranty, so if possible, you’re going to want to avoid buying new just to try this method out.
Ideally, this is something you’ll want to do outside, at least for the first time so that you can gauge how much smoke is going to be produced. It’s never any fun to have to unplug the smoke detector or swat it off the wall to shut it up in the middle of your roasting experiment!
If doing it outside is inconvenient, then do it in your kitchen, preferably directly under a light so you can get a good view inside the machine, and be sure to open the windows and doors to provide better ventilation. Once those preparatory steps are complete, you’re ready to begin.
Roasting Coffee Using An Air Popper
In terms of finding an alternate means of answering the question of how to roast green coffee beans, this one is probably the simplest and most straightforward to use. Highly recommended!
Wok This Way!
The first thing to say about this method is that although we recommend a stovetop wok, in reality, just about any good-sized saucepan will get the job done, although if you have a cast-iron skillet, then that’s a solid second choice.
The second thing to mention is that if using an air popper is the easiest of the alternate methods, this one is probably the hardest to get right, but it makes for a fun little experiment, and once you master it, you’ll be able to work some impressive coffee magic, even if you don’t have anything more than rudimentary tools available.
Before you start, make sure you do three things: Take the battery out of your smoke detector (because it WILL go off!), make sure your stove fan is turned on, and set to high, and open your doors and windows. This method is all but guaranteed to produce a lot of smoke!
Once you’ve done that, you’re ready to begin:
Roasting Beans Using A Wok
If roasting green coffee beans on the stovetop isn’t your cup of tea (or coffee!), then another option is to literally roast them in the oven. The process is largely the same, but there are a few key differences.
As with stovetop roasting, this method tends to generate a lot of smoke, so you’ll want to make use of your stove fan, open the windows, and take the battery out of the smoke detector because it’s a virtual certainty that you’ll set it off at some point in the process.
To make use of this method, you’re going to use a vegetable steamer, sitting atop a cookie sheet.
Roasting Beans in the Oven
The Grill Master Method
To use this method, follow the same steps that are listed with oven roasting, except of course that you’re going to place the veggie steamer and cookie sheet onto the cooking surface of the grill.
Two small details to point out here are as follows:
- Gas grills are much better for this kind of operation because most decent gas grills come with thermometers that allow you to properly gauge the temperature.
- The key advantage to this approach is that it doesn’t matter that it produces a lot of smoke because it’s not indoors and unlikely to make your smoke detector go berserk. For this reason, this approach gets our second highest recommendation, behind only the air popper method, which wins the day for sheer convenience.
Secrets to Home Roasting Success
Reading the various roasting methods described above is all well and good, but simply following the steps as outlined is no guarantee of success. To help reduce the slope of the learning curve, we’re providing the following tips and observations:
The biggest secret to your success lies in finding the “right” green coffee beans for roasting. Here, you’re looking for two things; beans that are of a consistent size, and beans that are of a consistent color.
The reasons why these two things are so important is that, if both conditions are true, all the beans you roast will be subjected to essentially the same heat, whatever roasting method you choose to employ.
That means that all things being equal, they’ll roast at about the same rate, but if you’re working with beans of wildly varying size and color (ripeness), then you’ll wind up with beans that reach different stages of the roasting process at the same time, which will impact the flavor of whatever drinks you ultimately produce using those beans (so smaller beans may wind up being dark-roasted, while your larger ones will come out medium).
The second big thing to remember is the fact that all green coffee beans will go through the same transition as you proceed through the roasting process. Having a familiarity with that process before you start will greatly improve your odds of producing a great-tasting batch.
With that in mind, here’s what you can expect to see:
