Roast your own coffee
fresh, at home.

A countertop coffee roaster is a small electric appliance — usually an air/fluid-bed or drum-style machine — that roasts green (unroasted) coffee beans in small batches right on your kitchen counter. It lets you control the roast level and brew coffee within days, rather than weeks, of roasting.

An air (fluid-bed) roaster tumbles beans in a stream of hot air for fast, even roasts in small batches, while a drum roaster tumbles beans inside a rotating heated drum for larger batches and more manual control over the profile. Both can produce great coffee; the right one depends on batch size, budget and how hands-on you want to be.

Yes — an air-style popcorn popper is one of the cheapest ways to try home roasting before buying a dedicated machine. Follow the popper manufacturer's instructions, roast outdoors or in a well-ventilated space, and never leave it unattended.

Green (unroasted) coffee beans are sold by specialty importers, retailers and some roasters in this directory, usually by the pound, in sample packs, or through a subscription. Compare origin, variety and harvest date, and buy only as much as you'll roast within a few months for best freshness.

Roast level is judged mainly by bean color, smell, and the timing of 'first crack' and 'second crack' — the audible pops as beans expand during roasting. Light roasts (city) stop shortly after first crack, while darker roasts (full city, Vienna, French) continue toward or into second crack.

It can be, with precautions: roasting produces smoke, chaff (papery skins) and high heat, so roast in a well-ventilated area, use a range hood or exhaust fan (or roast outdoors), keep chaff and flammable material clear of the heating element, and never leave a roaster unattended. Check your roaster's manual and local fire-safety guidance.

Most roasted coffee tastes best after resting ('degassing') for roughly 1 to 3 days for light roasts and up to a week or more for darker roasts, as trapped CO2 escapes. Store cooled beans in a container with a one-way valve and use them within a few weeks for the freshest cup.
