Things to Consider When Buying a Home Coffee Roaster

With some patience,  roasting coffee at home can be relatively simple, straightforward, and enjoyable. All you need are three items: green coffee beans, an airtight storage container, and a roaster.

Finding unroasted coffee beans may be the most challenging task in this endeavor, but now there are plenty of roasters available to consumers. A coffee roaster uses rapidly-moving hot air to roast raw beans uniformly by keeping them in perpetual motion.

The most common types for home use are fluid-air beds and drum roasters. Fluid bed roasters tend to roast quicker and hotter. The beans are roasted by whirling around and levitating on a bed of hot air. Drum roasters use a rotating chamber to roast the beans.

But which one is best for you and worthy of the investment? Here are a few things to consider when purchasing a roaster.

  • How much coffee do you drink? You’ll want to roast only the amount you consume in 4-5 days to retain maximum freshness.
  • How do you like your coffee? An even, complex, and bright roast? Then go with a fluid-air bed roaster. Prefer dark roast or mostly drink espresso? Then you might want to look into a drum roaster.
  • Have you roasted successfully before, or are you as green as the beans? If you are new to roasting, start with a quality fluid-air bed machine. It’s best not to start with the fancy, pricey roasters, and while you can roast with a popcorn popper, the results vary greatly.

The Fresh Roast SR540 is one of the most popular fluid-air bed roasters on the market. It’s an excellent choice for beginners because it’s affordable, simple to use, and produces great results. It features a real-time temperature display and one knob that controls nine levels of fan and heat settings, making it easy to adjust.

The roasting capacity is 4 scoops (120 grams of coffee, about 20 cups), so it’s good for smaller batches you can be sure to enjoy within the optimal freshness period (4-5 days). It’s easy to clean, and at only 14.4 x 8.4 x 8.3 inches and just under six pounds, it won’t overpower your counter space.

The SR540 model is the latest addition to the SR roasters. It replaces the well-loved SR500 version (sold-out and discontinued in 2019) with additional features and upgrades like an improved control band, wider fan range, a larger roasting chamber, and three times as many levels settings.

Features & Benefits

Are you the kind of coffee connoisseur that cares about freshness above all else? Does the thought of buying green beans directly from the source give you a thrill? Would you like to be able to control the lightness or darkness of the roast to your taste?

If so, then the experience of roasting coffee at home with Fresh Roast SR540 could be ideal. Here are a few benefits and features the popular fluid-air bed roaster provides.

Flexible Settings for Multiple Roasting Options

The Fresh Roast SR540 boasts adjustable fan and heat settings that range from 1-9 to give you control over your roast in real-time, thanks to the digital temperature display. You may need to experiment with the settings to determine the best heat and duration for your favorite bean.

One of the upgraded SR540 model features is a larger roasting chamber. More roasting room means better airflow for a more even roasting.

The fluid motion speed roast lowers the risk of scorching your coffee, and the glass chamber allows you to watch the beans and adjust the speed and heat as needed. Achieving the perfect roast requires some trial and error, but it’s a bit easier thanks to the SR540’s features.

Check Your Temperature

Lighter-bodied roasts require lower temperatures (350-400°F) and less time. Medium roasts range from 410-430°F, and medium-dark are best at 435-445°F. Dark roasts like espresso, French, and Italian roasts are good around 465°F, but no higher than 480°F, or they’ll char.

The recommended default roasting time for the SR540 is around 8 minutes at the higher (8-9) speed and level of heat. It might take some trial and error, but that’s part of the fun of roasting at home. Eventually, you’ll find your flow and flavor.

Listen Closely

Use your ears too. Coffee beans emit a popping sound called a “crack” when they roast. Once you hear the first crack, pay close attention to the color the beans are turning.

A good standard roast (medium to medium-dark) usually falls somewhere between the first and second crack. Even if you desire a dark roast, it’s typically best to turn off or down the heat when you hear the second, more subtle crackle sound.

Roast Your Beans, Not Your Home

An important benefit of using a quality fluid-air bed home roaster like Fresh Roast SR540 is that not only will you be less likely to burn the green coffee beans; you’re much less likely to burn your home or set off fire alarms.

Roasting beans in alternative roasters (stove-top popcorn maker or popcorn popper) might seem like a cheap and easy option. Still, it can create a lot of smoke, not to mention burn the beans or not achieve the desired roast because the air and heat distribution isn’t as uniform.

However, good ventilation is necessary with any roasting, so open a window if you can.

Easy to Clean

Roasting can be a messy endeavor. Not only can things get smoky, but when green beans are roasted, they leave behind their outer shell, the chaff, a residual byproduct of roasted beans.

The Fresh Roast SR540 has a built-in chaff collector, and it’s the only item you’ll need to clean. Just be mindful when taking out the chaff basket when full to prevent spilling. Tip: use a basting brush to dust out the remaining chaff residue once you’ve dumped it.

Fun fact: coffee bean chaff makes excellent organic compost for your garden!

A Sensuous Experience

It’s an experience for all of the senses!

The glass chamber lets you watch the action as your beans dance around the chamber. You’ll inhale the enticing aroma when the green coffee beans morph from yellow to light brown, to a deep, rich hue.

The popping sound (like popcorn!) lets you know your perfect cup of fresh java is moments away. You can touch and feel the difference between the raw, green bean and the roasted coffee, ready to be ground.

Of course, the best part is the taste. Sipping a cup of fresh coffee you roaster yourself is a sensory pleasure that’s hard to top.

Alternatives & Conclusion

The Fresh Roast SR540 is an all-around excellent product for beginners to intermediate home-roasters seeking a quality product at an affordable price.

It’s the new and improved version of the popular SR500 model, with nine heat and fan settings and a larger chamber for better airflow made of glass to watch the agitated beans roast before your eyes. It’s simple to use, easy to clean, and can make about 20 cups of coffee per roast.

However, no product is perfect for everyone, so here are a  few alternatives that might be interesting options for your roasting needs if this one doesn’t sound right for you.

For the serious home roaster who’s ready to make the investment, Kaldi Home Coffee Roaster is the ultimate choice. It is quite pricey, though, and requires a gas burner, but this industrial drum roaster can handle 300 grams per roast. It’s great for a semi-pro, small restaurant or cafe.

Popcorn Poppers are interesting alternatives for a novice roaster curious to give it a try without the commitment. On the opposite end of the spectrum, the Presto PopLite Hot Air Popper is surprisingly adept at roasting beans as it is popping popcorn. The bowl even catches the chaff.

But it can get smoky (use outside) and only hold 90 grams, so choose wisely when picking a popper/coffee roaster.

Happy Caffeinating!
