The concept, of course, seems seductive enough: slip a little paper-covered pod or plastic pouch or capsule in a machine, press a button, and out comes a single serving of fantastic, freshly-brewed coffee. No ground coffee on the counter, no arguments about whether to brew dark roast Kenya or decaf French Vanilla, no waste. A cup for everyone. You could brew a cup of pungent, dark-roasted Sumatra, your spouse a sweet, low-acid Brazil and your awkward, coffee-naive next-door neighbor an Irish Crème. In addition, in most cases you could brew tea and sometimes also make a cappuccino!
