For $800, the PicoBrew Pico will automatically make beer for you. Order ingredients from PicoBrew's website. They come in sealed packs called PicoPaks, and PicoBrew offers a wide variety of beers from many different microbreweries. PicoPak in hand, put it into the machine and hit start.
After you brew, you'll need to add yeast and wait for it to ferment, then move your beer to a serving keg and carbonate it. Pico helps with this last step -- called racking -- and includes the ingredients for every step.
It might not be as fast a Keurig is for coffee, but the PicoBrew Pico replicates a natural brewing process and offers a wide variety of beers you can brew. You might be able to brew beers with Pico that you wouldn't normally find in your state.
