For all the innovation and debate around the art of coffee making, the basic premise of dousing freshly ground beans with hot water doesn’t change much.  But the Ground Control coffee machine is out to break a cardinal rule of coffee brewing: don’t reuse the grounds.

Ground Control machines, made by Oakland, Calif.-based Voga Coffee Inc., are crowned with an eye-catching glass bulb with double helix extraction tubes that look like a Back to the Future prop. They’re a window into the brewing process of the machine, which washes coffee grounds with fresh water over separate cycles, usually three or four, each time catching different flavors and characteristics from the beans. The result is a preternaturally smooth cup, without the bitterness or thin flavor that reused grounds will conjure up.
