Product Description

Model GNB-20H is a digitally controlled coffee brewer with an embedded coffee grinder, all fit into a small form-factor both to save counter space, and to provide freshly ground coffee "on demand" immediately prior to brewing. The GNB-20H brews into 2.2 liter thermally insulated airpots, and as such, does not require nor have a warming surface.

The GNB-20H has two 6.5 pound hoppers to hold two different roasted coffee bean blends (e.g., standard and decaf) for fresh grinding. The unit comes standard with a stainless steel filter basket. There is a hot water spigot on the front of the unit.

The GNB-20HQ is the exact same machine, except that it comes equipped for 240 Volt service. This allows the GNB-20HQ to recover much more quickly between brewing cycles. Note that since there is no such thing as a "standard 240 Volt outlet," the GNB-20HQ ships without a power cord. To install the machine requires purchasing a cord to match your particular outlet at your local hardware store.
