Duo Parts

Listed from right to left – Duo’s lid – Stainless steel top – Stainless steel brew chamber – etched cone filter – silicine band – borosilicate glass carafe and a protective glass booty.


First you have to assemble this coffee steeping beast. Place etched cone filter into the chamber. The filters gasket should fit flush and snug in the bottom of the brew chamber.

Now place the brew chamber into Duo. If you look on the side of your brew chamber you will see 3 icons. The middle arrow icon is what you are going to use for proper alignment. Line up the arrows to the tops spout and slide the chamber down.

Once that is done twist the brew chamber clockwise to seal the top chamber. The sealed icon will align with the center of the spout. Ensure the gasket is placed on the bottom of the brew chamber so it meets the top of the plastic threading

The last step is to attach the brew chamber top to the glass carafe base. Place the silicon band onto the top of the carafe and fold over like so.

Now screw the Duo stainless steel brew complete brew chamber onto the top of the glass carafe. Make sure it is aligned squarely so you get a straight alignment and the threads screw smoothly to ensure a snug seal.

Alright it’s Brew Time

Let’s get your water heated first once the water is heated then you will grind your beans course like a french press or breadcrumbs.

Once you have your grind done load your fresh Dangerous into the brew chamber. You will see your beans expand and release the carbon dioxide trapped in the bean from roasting. This is called a coffee blossom. It’s the Hallmark of a fresh roast!. let the blossom finish and then give a little stir using a spoon.

Place the top on that bad boy and let your coffee brew for 4 to 5 Minutes. When the time is up simply twist the top of the Duo counterclockwise in order to release the coffee brew into the glass carafe. the process should only take 30 to 45 seconds

Enjoy your strong tasty and smooth brew!
