PRECISE TEMPERATURE CONTROL

DUO is powered by Heatworks’ patented Ohmic Array Technology.

Different coffees and teas require different temperatures (most coffee is best between 195 and 205° F, green teas are brewed at 175° F) for proper brewing. Typical kettles heat a full reservoir of water so that both coffee and tea are made at the same temperature. Instead, the DUO Carafe uses our patented Ohmic Array Technology to heat water instantaneously as you pour, leaving the water in the reservoir cool. This means you can make a perfect pour-over coffee, reset the temp, brew a perfect cup of tea, and then pour yourself a cool glass of water, all without refilling or changing the water in the carafe.
