How to Roast Barley for Deliciously Bold Coffee

I love starting my mornings with a delicious cup of coffee. But not just any coffee – I prefer coffee with bold flavors and a rich aroma that can wake up my senses. That’s why I have turned to roasting my own coffee beans at home, specifically barley. Roasting barley for coffee gives it a unique and intense flavor that can rival any coffee shop brew. It may sound daunting at first, but with the right technique and some patience, you too can enjoy a cup of deliciously bold coffee made from roasted barley.

Why Roast Barley for Coffee?

You may be wondering, why go through the trouble of roasting barley for coffee when there are plenty of pre-roasted coffee beans available? Well, the answer is simple – freshness and customization. When you roast your own barley, you have complete control over the flavor profile of your coffee. You can adjust the roast level to your liking, from a light roast for a brighter and more acidic taste to a dark roast for a bold and smoky flavor. Additionally, roasting your own barley ensures that your coffee is as fresh as possible, as you can roast small batches as needed.

What You’ll Need

Before you embark on your barley roasting journey, it’s important to gather all the necessary tools and ingredients. Here’s a list of what you’ll need:


Start with high-quality barley that is specifically meant for coffee roasting. You can find it at specialty stores or online. Make sure it’s fresh and free from any contaminants.

Roasting Equipment

There are several methods you can use to roast barley at home. The simplest is using a hot air popcorn popper, as it provides even heat distribution and allows you to see the beans as they roast. Alternatively, you can use a stovetop popcorn popper, a cast-iron skillet, or even an oven. Choose the method that suits you best.

Colander or Mesh Sieve

To cool down the roasted barley quickly and stop the roasting process, you’ll need a colander or mesh sieve. Make sure it’s large enough to hold the amount of barley you’re roasting.

Storage Container

Once your barley is roasted, you’ll need airtight containers to store your coffee beans. Mason jars or coffee bean storage containers with a one-way valve are ideal for preserving freshness.

The Roasting Process

Now that you have all the necessary tools, it’s time to dive into the roasting process. Here’s a step-by-step guide on how to roast barley for deliciously bold coffee:

Step 1: Preheat Your Equipment

Regardless of the roasting method you choose, preheating is crucial. This ensures even heat distribution and helps achieve consistent roasts. Preheat your equipment according to the manufacturer’s instructions.

Step 2: Measure and Prepare the Barley

Measure the desired amount of barley you want to roast. Keep in mind that the beans will expand during roasting, so take that into account when determining the quantity. Rinse the barley with cold water and pat it dry using a clean towel.

Step 3: Start Roasting

Depending on your chosen roasting method, carefully add the barley to the heated equipment. For a hot air popcorn popper, add a single layer of barley and cover it. If using a stovetop popcorn popper or skillet, stir constantly to ensure even roasting. Keep a close eye on the barley as it begins to roast and pay attention to the aroma.

Step 4: Monitor the Roast

As the barley roasts, it will go through different stages, each offering a unique flavor profile. The first stage is the “first crack,” indicated by a popping sound similar to popcorn. This stage produces a light roast with more acidity. If you prefer a darker roast, wait for the “second crack,” which gives rise to a sweeter and bolder flavor.

Step 5: Cool and Store

Once the barley reaches your desired roast level, quickly transfer it to a colander or mesh sieve to cool down. Shake the colander or sieve gently to remove any chaff or leftover husks. Allow the beans to cool completely before transferring them to a storage container. Let the beans degas for at least 24 hours before brewing your first cup.

Experimenting with Roast Levels

Part of the joy of roasting your own barley for coffee is experimenting with different roast levels. Start with a small batch and try different roast levels to find your preferred flavor profile. Light roasts offer a bright and crisp cup, perfect for those who appreciate a more acidic taste. Medium roasts strike a balance between acidity and boldness, while dark roasts provide a full-bodied and smoky experience. Don’t be afraid to try different combinations and make note of your favorites.

Brewing Your Roasted Barley Coffee

Now that you’ve successfully roasted your barley, it’s time to brew a delicious cup of coffee. While the brewing method can vary depending on your preference, here’s a simple guideline to get you started:

Grind the Beans

Grind your roasted barley beans just before brewing. Aim for a medium grind consistency, similar to that of drip coffee. This ensures optimal extraction and flavor.

Brewing Method

Choose a brewing method that suits your taste. You can use a coffee maker, a French press, or a pour-over device like a V60 or Chemex. Experiment with different brewing techniques to find the one that brings out the best flavors in your roasted barley coffee.

Water Temperature and Ratio

Maintaining the right water temperature and ratio is key to a good cup of coffee. Aim for water temperatures between 195°F (90°C) and 205°F (96°C). Start with a coffee-to-water ratio of 1:16, and adjust it to your taste preferences.


Sit back, relax, and savor your cup of freshly brewed roasted barley coffee. Take note of the flavors and aromas that come through, and appreciate the effort you put into creating this delicious beverage.

In conclusion, roasting your own barley for coffee is a rewarding experience that allows you to customize the flavor profile of your coffee beans. With the right equipment and a little practice, you can achieve deliciously bold coffee that rivals any coffee shop brew. So why not give it a try?
