The truest expression of coffee

Osma is a portable coffee device that makes cold brew in under two minutes using our biodegradable pods or your favorite coffee.


Cold brew in a flash

Start with chilled water to get the smoothness and complexity of overnight cold brew in as little as one minute.

Intense and balanced hot brew

You can also use hot water to brew with Osma for a rich, complex, and balanced cup.

Pods done right

Our biodegradable pods go directly into your compost or garden. Also available empty so you can fill them with your favorite coffee. Order pods here

Osma connects to your iOS device via Bluetooth. Use our app to discover new pods and create your own recipes.

Cycle Infusion

Osma uses a patent-pending combination of pressure, immersion, and circulation to preserve and amplify each coffee's unique character.

"What we immediately noticed is the Osma did in fact reveal a spectrum of flavor and aroma masked or destroyed while preparing a pour-over or using the combination of high pressure and heat of a dedicated espresso machine."

-Gregory Han, design and technology writer for New York Times Wirecutter, Dwell, Design Milk, and more


With 20+ cups of coffee per charge, exceptional coffee is always within reach.

"Cold brewing with Osma is unlike any process I've experienced. It reveals new notes in coffees I've developed and know intimately. The taste is complex and very smooth. "

-Hiver van Geenhoven, Chromatic Coffee co-founder

How to use Osma

1. Open

Press the button just below the cup to release the latch. Swing the cup up and back to open the brew chamber.

2. Load

Drop the pod of your choice into the brew chamber

3. Close and Fill

Press firmly on the front rim of the cup until you hear a click to securely close the brew chamber. Then add hot or cold water.

4. Press Start

Press and release the main button to start the brew cycle that you selected from within the app.

5. Brew

As long as the light is pulsing green the brew is still in progress- pauses in the pump's hum are a normal part of most recipes.

6. Eject

After enjoying your coffee, open the brew chamber again and tilt the Osma as if you're about to pour it out. Then press the main button with your thumb to eject the pod.

Coffee is just the beginning

We're working with our partners to release a collection of tea pods in the coming months.
