Mueller Hydro Press Coffee Maker

This pot is a variant on the AeroPress concept - soak the coffee in hot water, then use pressure to extract more flavour than possible with a French press pot. The pot consists of two parts, a tumbler and a core chamber. You put coffee in the bottom of the tumbler, just as you would in a French press pot, then insert the core plunger part way and let the grounds soak for 2-4 minutes. After you've let let the grounds soak, you slowly push the core plunger down to the bottom until you can't go any further. Then you're ready to pour the coffee. A couple of comments on usage and storage. As another reviewer pointed out, you will struggle to pull the pot apart if you do not turn it upside down. Even if you turn it upside down, you may find that the ball will get stuck in the down position in the core chamber and you still won't be able to pull the pot apart. If this happens just hit the bottom of the tumbler with your palm (not too hard, though) and the ball should come unstuck and allow you to pull the pot apart. I would also recommend not storing the pot as a single unit, separating the two parts, the core chamber and the tumbler, when storing. The plunge in the core chamber has a kind of O-ring that serves as the means to create pressure. Similar to the AeroPress, if you store the pot as a unit, you will eventually find that the seal will deteriorate over time because that O-ring will become compressed. The AeroPress has a similar recommendation in its instructions.
