The AeroPress is a coffee making system ideal for travel, or brewing a small amount at the home or office. It makes a very clean, sediment-free cup in a short period of time, and it is easy to clean up. You just need ground coffee, hot water, and a mug (ideally you brew directly into a mug, not included in the kit).
Brewing with the AeroPress gives good control over the variables - you can easily adjust the water temperature or water-to-coffee ratio to change the results. In my tests, the cup results match both the full pot Technivorm brews and my cupping results (the process where we mix grinds directly with water and use a spoon to taste many coffees at once.)
After a lot of frustration on vacations using friends' and relatives' dirty, low temperature coffee makers, the AeroPress seems like a perfect match for the home roaster away from their home brewing setup.
There's one big problem with the brewer: the claims made by the manufacturer ! They mean well and want to sell their product, but this is not an espresso maker, nor are the other "made-for-TV" type exaggerations on the package true. This is a brewer that makes a concentrated coffee, then you add hot water to enjoy. It will have other uses too: making iced coffee, coffee for cooking recipes, storing a cold concentrate for later use, etc.
The instructions that come with the brewer are good, but I have made my own AeroPress pictorial instructions to show the way I think it should be use. I know, it's no looker. Someone here commented that it has all the charm of a medical device. Bad packaging and bad looks doesn't mean bad coffee though; the AeroPress is well made, the instructions are good, it is easy to use (1 or 2 cup learning curve), fast, easy to clean, and will travel well. I think positive features have made it a good brewer to add to my "arsenal" ... maybe you have a need for this, too.
