Alessi 9090 Espresso Maker 300ml by Richard Sapper - 6 Cup Stovetop Espresso Coffee Maker for Home & Office Use | Perfect for Italian Coffee Lovers & Gift Giving

This is my favorite stovetop mocha pot. It is not cheap, but the build quality, ease of use, durability, and just genuine pleasure in using an excellent tool all make the 9090 worth the money (unless you are on a tight budget). I used Biletti stovetop mocha pots for years, and they work absolutely fine. The Alessi 9090 is easier to use since the top just snaps on and does not screw on. The 9090 is also a work of art or fine design more accurately. So, if you don't mind shelling out more money, you will enjoy it and it makes a fine coffee. A single word of caution: be sure not to fill beyond the pressure valve, do not top the coffee off in the ground coffee receptacle (leave less than you would with the Billet and leave a bit of space from the top for the coffee to expand into), and perhaps grind the coffee a bit more coarse than the Billet. Otherwise, you run the risk of steam escaping the junction of the water chamber cum coffee grind holder and the upper brewed coffee receptacle. The end result is little to no coffee entering into the upper brewed coffee receptacle. Coming from a Billet I made all those mistakes until I read the very wise response in the questions and answers.
