How To Roast Coffee Beans In A Popcorn Popper: Detailed Guide

Roasting coffee in a popcorn popper is a simple and budget-friendly way to roast your own beans at home.

Here’s a step-by-step guide to help you get started:

What You’ll Need

  • A popcorn popper with a metal popping chamber and side vents (not bottom vents)
  • Green coffee beans (about 3 to 4 ounces is ideal)
  • Colanders or bowls for cooling
  • Kitchen timer (optional)
  • A scale (optional)


Step 1: Set Up Your Roasting Area

Before you start roasting coffee in your popcorn popper, choose a suitable outdoor location near an electrical outlet.

Remember, roasting can produce some smoke, so it’s best to keep it away from open windows.

Step 2: Prepare Your Popcorn Popper

Plug in your popcorn popper and turn it on, ensuring it’s ready for action.

Step 3: Measure Your Green Coffee Beans

Pour around 3 to 4 ounces of green coffee beans into the popping chamber of your popcorn popper.

If you don’t have a scale, a rough estimate of 1/4 to 1/3 cup will work.

Step 4: Start the Roasting Process

Begin roasting your coffee beans for 3 to 7 minutes, depending on your preferred roast level.

Keep in mind that the beans will continue to darken after you remove them from the popper, so stop roasting just before they reach your desired color.

Step 5: Listen for the “Cracks”

After about 3 minutes of roasting, you’ll hear a distinct “first crack.”

This signals that the beans are roasting.

Depending on your taste, you can either stop here for a lighter roast or continue to the “second crack,” which occurs after a few more minutes for a darker roast.

Step 6: Cool the Roasted Beans

Once your beans are roasted to your liking, switch off the popcorn popper and carefully pour the beans into a colander or bowl for cooling.

Step 7: Ensure Proper Cooling

Stir the beans for 5 seconds every 15 seconds to cool them down effectively and remove any chaff.

Step 8: Store Your Freshly Roasted Beans

Store your freshly roasted coffee beans in an airtight container to keep them fresh and preserve their flavor.

A Couple Of Things To Note

Roasting coffee in a popcorn popper may void the manufacturer’s warranty.

Additionally, make sure to provide proper ventilation to avoid smoke buildup while roasting your beans.

What Is The Best Way To Roast Coffee Beans?

The best way to roast coffee beans depends on your specific needs and budget.

There are several methods to choose from, and your decision should be influenced by factors like the quantity of roasted coffee you require and your budget constraints.

Some popular methods include using an electric popcorn popper, a skillet, a stovetop popcorn popper, or even a simple cookie sheet in your oven.

The roasting process typically consists of three main stages: drying, browning, and development.

During the drying stage, the coffee beans lose moisture and become more brittle.

As you move into the browning stage, the beans start to turn brown and release carbon dioxide.

Finally, in the development stage, the beans continue to darken and develop their unique flavor profile.

To embark on your home coffee roasting journey, you can use tools like a stovetop roaster, an electric roaster, or even a heat gun and a whisking bowl.

It’s essential to keep the beans in motion to ensure they all reach an even level of roasting.

When roasting coffee beans, remember to consider the quality of the green coffee beans you’re using, the batch size you want to roast, and the roast level that suits your taste preferences.

Your choice of method will depend on these factors, so explore and experiment to find the best approach for your coffee roasting adventure.

Where Can I Buy Green Coffee Beans?

If you’re looking to purchase green coffee beans, the most convenient option is to explore online retailers.

There’s a wide selection available through various online stores such as Amazon, Etsy, Coffee Wholesale USA, Good Morning Coffee Roasters, MoreCoffee!, Bonanza, and Burman Coffee Traders.

The prices and quantities of green coffee beans can vary depending on the specific store and the type of coffee beans you’re interested in.

While online shopping offers a vast array of options, finding high-quality green coffee beans in physical stores can be more challenging.

You might not typically find green coffee beans at your local grocery store.

However, if your neighborhood coffee shop roasts its beans, it’s worth inquiring whether they sell green coffee beans.

This could be a way to obtain quality beans and support a local business at the same time.

The Benefits of Roasting Coffee at Home

Roasting coffee beans at home brings with it a host of benefits that make it a rewarding and satisfying hobby.

Here are some of the advantages of taking the DIY approach to coffee roasting:


When you roast your own coffee beans, you have complete control over the roasting process.

This means you can enjoy coffee at its peak of freshness.

Store-bought beans may sit on shelves for months, but with home roasting, you can savor the rich flavors and aromas of coffee just days or hours after roasting.

Flavor Customization

Home roasting allows you to tailor your coffee to your precise taste preferences.

You can experiment with different roast levels, bean origins, and blends to create a unique cup of coffee that suits your palate.

Whether you prefer a light, medium, or dark roast, you’re in charge.


Green coffee beans are more affordable than pre-roasted ones, making home roasting a cost-effective option in the long run.

By buying green beans in bulk, you can save even more and roast on demand, reducing waste and ensuring you always have fresh coffee on hand.


The aroma of freshly roasted coffee is an experience in itself.

The process fills your home with the delightful scent of roasting coffee beans, creating a sensory experience that store-bought coffee can’t replicate.

Challenges and Limitations of Popcorn Popper Coffee Roasting

Using a popcorn popper for coffee roasting is an exciting and cost-effective way to dive into the world of home roasting.

However, it’s crucial to acknowledge some of the drawbacks associated with this method to manage your expectations and overcome potential challenges:

Batch Size Limitations

Popcorn poppers are generally designed for small batch sizes, typically around 3 to 4 ounces of green coffee beans.

If you’re looking to roast larger quantities, you may need to invest in a more substantial roasting setup.

Limited Roast Profile Control

Popcorn poppers often provide limited control over the roast profile.

While you can influence the roast level by adjusting the roast time, it may be challenging to achieve precise and consistent results compared to dedicated coffee roasters.

Noisy Operation

Roasting coffee in a popcorn popper can be quite noisy due to the powerful fan and heating element.

This noise may not be suitable for early morning or late-night roasting sessions.

Lack of Smoke Management

The roasting process can produce smoke, and popcorn poppers may not have effective smoke management systems.

It’s crucial to roast in a well-ventilated area or outdoors to avoid smoke-related issues.

Potential Popper Wear and Tear

Using a popcorn popper for coffee roasting may shorten its lifespan or void the manufacturer’s warranty.

The extended heat exposure and agitation during roasting can cause wear and tear on the popper.


Roasting coffee beans in a popcorn popper is a simple, cost-effective way to elevate your coffee experience.

With a few steps and some practice, you can enjoy the freshness, flavor customization, and creative journey of home roasting.

So, grab your popcorn popper, embrace the aromatic adventure, and savor the satisfaction of your very own roasted beans.

Happy roasting!


Is it necessary to preheat the popcorn popper before adding green coffee beans?

Can I roast larger batches of coffee beans in a popcorn popper, or is it limited to small quantities?

Popcorn poppers are generally best for roasting small batches of coffee beans, typically around 3 to 4 ounces.

Attempting larger quantities may result in uneven roasting and less control over the process.

If you need to roast larger amounts, consider investing in a dedicated coffee roaster.

Can you roast coffee in an air fryer?
