This $500 Coffee Maker Brews a Near-Perfect Chemex-Style Pot

Then I saw a coffee maker that could make consistently delicious Chemex-style pour over, staring at me across the room.The Ratio Eight is a pour-over Chemex-style machine with a built-in robot brain that has been programmed to eliminate human error from one of the most difficult brewing techniques out there. With the press of a button, the machine begins gurgling water to the exact right temperature (200 degrees Fahrenheit, according to the Specialty Coffee Association of America), pulling it up through internal glass tubing systems.Just as a manual pour over would, the Ratio first delivers a “Bloom” cycle. Better yet, I know each and every morning will be filled with them.The only complaint I have about the Ratio is that, because the carafe is glass and not heated from the bottom of the machine, it isn’t very insulating, which allows your coffee to cool if you don’t drink it. Plus, it matches your machine.The Ratio Eight is one of two premier automated pour over coffee makers to choose from, the second being the $350 Chemex Ottomatic Coffee Maker 2.0. Every machine is assembled by hand, and whether you opt for a hand-blown glass water tank or go with the standard BPA-Free plastic option, the coffee carafe is still made of hand blown glass.All of this detail means the price of the Ratio is steep.
