There are many ways of extracting coffee goodness from grind to cup, but none much better than the Aeropress. Whenever I am making one or two cups, the Aeropress is my brewer of choice.
Like a French Press, it allows the coffee to steep as long as desired to customize the brew before plunging, but has the advantage of a small filter which allows any grind level to be brewed while remove all the grit. If that is not enough, it is easy to clean by unscrewing the filter cap and popping the coffee puck into the compost. A quick rinse and it's ready to go again.
So before you go out and spend $150 on a single cup brewing system that takes up counter space, uses very expensice ( $30/lb) coffee pods that choke our landfills and at best produces a stale cup of coffee, try an Aeropress. It just might change your coffee life forever. It did mine.
