Duo’s full immersion and etched steel filter ensures a full bodied, clean tasting cup. Much like a French press, Duo’s brewing chamber lets coffee grounds hang out in hot water for a full immersion and robust extraction. Unlike the French press, Duo’s double filter ensures no gunk at the bottom of your cup.
Duo is a perfect combination of French press and drip coffee. There’s no worrying about underextracting coffee and ending up with sad, brown water.

Step 1 | Prepare Duo
Place the etched cone filter into the chamber. The filter’s gasket should fit snugly in the bottom of the chamber.
Insert the brew chamber with the middle ARROW icon facing the spout. Twist the brew chamber clockwise to align the LOCKED icon with the spout. Coffee will not drain into the glass carafe while Duo is in the locked position. Screw Duo’s stainless steel top onto the bottom glass carafe.

Step 2 | Measure Coffee Grounds
Grind about 45 grams (7 tbsp) of coffee as fine as breadcrumbs into the brew chamber.

Step 3 | Add Water
Add hot water (about 92-96°C) to the brew chamber. Fill to the top of the inverted cone filter. Give a quick stir to help with the extraction. Place the lid on and let the coffee sit for 4 minutes.

Step 4 | Twist & Drain
After 4 minutes, twist the top of Duo counterclockwise to align the RELEASE icon with the spout. This will release the coffee into the glass carafe. Duo should take 30-45 seconds to drain.

Step 5 | Serve & Enjoy
Duo is ready to serve. Enjoy!
