Why Roast Coffee Beans at Home?
As any coffee aficionado knows, nothing beats the flavor of freshly toasted coffee beans via the process of roasting coffee beans at home. Roasting green coffees yourself allows you to:
- Save money compared to buying premium toasted coffee
- Customize your roast level exactly how you like it
- Explore single-origin grains from around the world
- Roast and enjoy fresh coffee anytime
While dedicated roasting machines can cost hundreds of dollars, I’ve found that repurposing a basic air popcorn popper provides a quick, easy, and inexpensive home coffee beans for roasting solution.
What You’ll Need to Get Started
Roasting coffee at home with a popcorn popper only requires a few items:
- Air popcorn popper – Any popper with a metal chamber and side vents will work. I use the cheap $20 West Bend Air Crazy.
- Green coffees – Buy 3-4oz of your preferred origin. Lightly toasted grains are ideal for roasting.
- Colanders or bowls – For cooling the freshly toasted beans.
- A kitchen timer or phone
- A scale (optional but recommended)
- A thermometer (optional)
That’s it! Now let’s walk through the simple process of roasting step-by-step.
Step 1 – Prepare the Popcorn Popper
Plug in and turn on your popcorn popper. Place it on a heat-safe surface outside if possible – it will vent some chaff during roasting.
Pop off the plastic top piece to allow easy access.
Step 2 – Add the Green Coffee Beans
Add 3-4oz of your favorite green coffee to the popping chamber. I’ve found this small batch size works best.
Using a utensil, stir the grains around initially until the hot air can move them consistently.
Step 3 – Listen for the “Cracks”
Here’s where you’ll want to pay close attention. As the grains roast, they will go through two distinct phases called “cracks”:
First Crack – Starts around 2.5-3 minutes. You’ll hear slight , popping sounds as the grains reach 360-370°F. The grains will turn brown and smell like coffee.
Second Crack – Starts around 4 minutes with a higher-pitched popping like rice krispies. Beans will be around 420-430°F. You’ll see more smoke.
Step 4 – Remove Beans at the Desired Roast Level
Using the cracking sounds, you can easily identify slight, medium, and deep roast levels:
- Light Roast – Remove just before the first crack
- Medium Roast – Remove during the early second crack
- Dark Roast – Remove mid-way through the second crack once popping slows
I prefer a light-medium roast to highlight fruity notes in the bean. Dark roasts can mute these flavors.
Step 5 – Cool the Beans Fast
Once roasted, quickly pour the hot grains back and forth between two colanders or bowls. This cools them rapidly to stop the roasting process.
Some chaff will blow away in the process.
Step 6 – Rest and Store the Beans
Allow the toasted grains to rest for 12-24 hours before brewing. This helps improve and settle the flavor.
Store the grains in an airtight container away from light and moisture. Use or freeze within 1-2 weeks for best freshness.
And that’s it – freshly toasted artisan coffee in just 5 minutes! With a bit of practice using an air popcorn popper, you’ll be able to easily customize your preferred roast levels.
The small 3-4oz batch size is perfect for experimenting with new grains and always having the freshest coffee on hand. Let’s look at some common questions about popper coffee beans roasting next.
