Home coffee roasting is a terrific way to ensure fresh beans for your daily cup of joe—and if there’s one thing coffee lovers agree on, it’s that fresher means better. Experts say coffee beans are best used between two to 14 days after roasting. Any longer than that and the coffee will degas too much and lose flavor.
Roaster options are fairly limited, especially compared to other coffee-related appliances like grinders and milk frothers, but the process itself is simple and takes just minutes. The two main kinds of rosters are manual and automatic, both of which are covered on this list. The former is more affordable but likely has a smaller capacity; the latter is easier to use and typically includes electric or gas devices.
For fresh, ready-to-grind beans, here are the best home coffee roasters.
Best Overall: Fresh Roast SR540 Coffee Roaster
The Fresh Roast SR540 turns raw coffee into a delicious, ready-to-brew batch of beans, and the whole process takes just 10 minutes. Simply turn a knob to select between nine levels of heat and hit go. The item is easy to use, yet it comes with a few advanced features, like a real-time temperature reader and the ability to cool beans once they're finished roasting.
Depending on your coffee-roasting needs, however, the size of the product might be a considerable drawback. It holds just 4 ounces coffee beans, which works great for personal use but may be a bit small if you want to roast a lot of beans at once. Aside from that, the Fresh Roast SR540 is highly reviewed, affordably priced, and a great way to upgrade your at-home coffee.
Best Design: DYVEE Gas Coffee Roasting Machine
This sleek, lightweight roaster only needs to be placed over a gas stove to get your morning coffee started. It's primarily made of stainless steel, but the drum is made of sturdy quartz glass, which lets you see the beans change color as they roast. A wooden handle provides an elegant touch as well.
The roasting process for this item is more hands-on than that of electric models, but it gets the job done nonetheless, and as a silver lining the manual turning offers more control over the beans. It has a fairly large capacity, holding up to 400 grams of coffee beans, but 200 to 300 grams per batch is recommended for optimal use.
Keep in mind that the purchase does not include a gas burner, even though one is featured in photographs. Customers also recommend outside use, as this roaster can get smoky.
Best Budget: NUVO Eco Ceramic Handy Coffee Bean Roaster
Make your coffee an old-school fire-roasting process with this ceramic bean roaster with a cowhide grip. While it’s a serious tool, it’s attractive enough to use as a décor item when it’s not roasting beans, so you can leave it on display rather than hiding it in the pantry. Plus, it comes at a budget price. This has a waffle-shaped internal structure for even roasting, while the rear hole lets you hear the telltale popping sounds that signal the stages of the roasting process.
The ceramic material has good thermal conductivity to roast the beans properly, while the cowhide grip protects your hands, but it’s wise to wear gloves to protect from heat. The hot roaster should not be placed on a cold surface or immersed in water.
Best Splurge: KALDI Motorized Home Coffee Roaster
This roaster delivers the look, feel, and final product of a coffeehouse-worthy machine. It will entirely transform your at-home coffee experience, exposing the optimal flavor notes in every batch of beans.
A high price tag makes the item a long-term investment, but the features and performance make it worthwhile. The stirring drum holds up to 250 grams of coffee beans, though 200 grams is the recommended amount per batch. Fully motorized, all you have to do is place the roaster over a gas burner for heat to be evenly and thoroughly distributed across the raw coffee beans. Other features include an easy-to-read thermometer, a probe rod, and a reliable chaff holder. If this machine isn't quite the right fit, measuring 14.1 x 8 x 22.1 inches, KALDI also manufactures a high quality mini roaster that is smaller in size and slightly cheaper.
Best Large Capacity: MIFXIN Home Coffee Roaster Machine
MIFXIN's Home Coffee Roaster not only has one of the largest bean capacities you can find, it's also one of the most affordably priced machines out there. It holds a whopping 750 grams—roughly 1.6 pounds—of your favorite coffee beans. Customers give the item especially high marks in durability and value for money, suggesting that it's a sound long-term investment for coffee lovers who want to craft their favorite caffeinated drink from step one.
This roaster is also extremely user friendly. The inside is lined with non-stick material for easy cleaning, and it's simple to adjust the temperature thanks to a dial that goes from 0-240 degrees. Flip the switch and in just 30 minutes you'll have rich, home-roasted coffee beans—or, as an extra perk, you can roast various nuts.
Best Alternative Roaster: Wabash Valley Farms Whirley Pop Stovetop Popcorn Popper
One of the worst-kept secrets among home coffee roasters is that some popcorn poppers can also be used for roasting coffee. This stovetop popper won’t offer you temperature control or smoke suppression, but it’s a dual-use item that does the job well.
Since you can’t control the smoke, you should use this outdoors for coffee roasting or have an open window and a fan ready to remove the smoke and odor. Stir the beans constantly to ensure even roasting and listen for the popping sounds to gauge the roasting stages. Since coffee beans don’t fly around like popcorn, you can open the lid towards the end of the roasting time to judge the roasting color. You can roast about 1 cup of beans per batch in this popper
Capacity Is coffee roasting going to be an occasional hobby or a new passion? Most home roasters are designed to roast small amounts of coffee, but it’s a good idea to consider how often you want to roast and the volume of beans you plan to roast at a time.
Manual or automatic From fully manual to fully automatic, you can find a coffee roaster that fits your needs. Fully automatic machines make roasting easier but are more expensive, while manual machines are more budget-friendly but require constant attention during the roasting time.
Smoke suppression Coffee roasting produces quite a bit of smoke, no matter what method you use. If you’re going to be using your roaster outdoors, the smoke shouldn’t be a problem, but if you prefer to do the roasting in your kitchen, it might be wise to pick one with a smoke suppression system. You should also consider whether you can position your roaster near a window or under a vent fan.
