Why Roast Your Own Coffee
Roasting your own coffee is a fun hobby that allows you to flex your creative muscles and enjoy a unique brew.
Here are other practical reasons to roast your coffee at home.
- Freshness: Freshly roasted beans reach their peak after about 3 days. That means you’ll enjoy a flavorful coffee because it has retained most of the natural oils.
- Control: Gives you greater control over the roast level and flavor profile. Whether you prefer light, medium, or dark roasts, you can achieve your ideal degree. Also, you can incorporate your favorite varieties and blends to brew a unique cup of coffee.
- Cost-effective: Roasting coffee can be a reasonable option in the long run. Roasted beans cost about $15 per pound (450g), while green beans cost between $6 and $12 per pound (450g).
A Rough Guide To Roasting Your Own Coffee
Here’s a rough guide to get you started with home roasting.
- Get your hands on green coffee beans: You can buy them online or at a specialty coffee shop.
- Preheat your roasting equipment: Preheat the roaster to its maximum temperature.
- Measure your beans: A good starting point is to use around 100g (3.5 oz) of beans for each batch.
- Start roasting: Add the green coffee beans and start the roasting process. Monitor the beans to ensure they’re evenly roasted.
- Cool the beans: Once you achieve your desired roast degree, remove them from the heat and cool them down quickly.
- Let the beans rest: It’s vital to let the beans rest for 48-72 hours. This allows the flavors to develop.
What To Look For In A Coffee Roaster
Knowing what to look for in a coffee roaster ensures you buy one that’ll fulfill your needs.
Below’s a comprehensive guide to aid you in your pursuit.
Different types of coffee roasters
- Drum roaster: Drum roasters use indirect heat to roast beans. The heat source can be electricity, gas, or wood. The inside of the machine has a cylindrical chamber that rotates. As it rotates, the beans come in contact with heat, which ensures an even roast.
- Hot air roasters: Similar to a popcorn maker, air roasters force heated air through a perforated plate under the coffee beans. As heat transfers to the beans, the beans circulate for an even roast.
Manual vs Automatic
Manual roasting is a more hands-on process, and the only aspect you can control is temperature. You’ll need to monitor the process and make adjustments to ensure the beans are roasted evenly.
Automatic roasters use built-in controls to regulate heat and airflow.
You can set the roaster to a specific temperature and let it run without needing to monitor it as closely. They can be a more convenient option, as they require less hands-on attention, making them an excellent choice if you are just starting out.
Home roasters have a capacity of 75-250g to 800-1kg. When seeking the ideal capacity, ask yourself the following questions.
- How often are you going to roast?
- How much coffee do you need per week?
- Do you see yourself moving from home roasting to a professional level?
We recommend you choose a roaster that’s not too large or too small in capacity. Having flexibility allows you to experiment until you find a sweet spot that gives you perfectly roasted beans.
Most manual roasters have a dial that allows you to control temperatures. Others have a user-friendly control panel to control roast mode to cooling mode.
With an automatic roaster, you can employ a completely hands-off approach mode. You can also connect the roasters to a software, allowing you to make changes in real time and create repeatable profiles.
Beans get roasted to more than 200°C (392°F) and this process produces a lot of smoke.
Unless you have a strong vent to release the smoke, it’s best to invest in a device with an afterburner to reduce the amount of smoke emitted.
Because beans roast at 200°C (392°F) and above, they retain heat and may continue to roast way past the desired roast degree. For this reason, they have to be cooled below 40°C (104°F) within 4 minutes.
Some roasters will cool the beans within 4 minutes or fewer, while others have a longer cooling cycle.
It’s best to buy an appliance that cools within 4 minutes.
If, for whatever reason, you wind up with a roaster that doesn’t cool quickly, you can pour the beans into a metal colander and shake them around until they cool.
Keeping it clean
Cleaning the chaff off the roaster and its surroundings can be messy. (Most) Roasters come with a chaff collector so you don’t have to deal with an extra messy cooling tray.
You simply take the tray and empty the chaff into the bin or outside.
What’s best is you don’t have to perform a deep clean after every roast. A damp cloth wipe does the trick.
Also, choose a roaster with a removable, washable chamber.
Home roasters can range from $35 to over $1000. The more expensive roasters tend to offer more features and larger capacities.
Consider how much you are willing to spend and what features are most important to you.
