The Grindmaster GNB-21HQ Grind'n Brew dual bean decanter grinderbrewer will transform your commercial coffee brewing!  Save space with its compact design and save money with just one purchase instead of two as well as a decreased energy bill that only has to account for the stand-by costs of one machine.

Accuracy in Brewing
The coffee brewed by a Grindmaster Grind'n Brew is guaranteed to be accurate.  It boasts the PrecisionBrew technology of Grindmaster that ensures temperature is held to within +/- just 1 degree of the optimal brewing temperature

Dual Bean
Coffee brewed instantly following grinding is guaranteed to be some of the freshest, most aromatic coffee you can offer.  And, with the dual bean decanters in the Grindmaster GNB-21HQ, you can not only offer one type of coffee, but two.  This is particularly useful for serving both regular and decaf or even regular and a specialty blend.

The Grindmaster Grind'n Brew coffee grinder with coffee maker has a pulse-brew system that allows the user to regulate the number of pulses within a batch as well as the pulse-on and off times.  You'll see extractions up to 20% stronger.

Fool Proof
Worried about it taking too long to figure out a new machine?  You shouldn't be!  Not only is this Grindmaster coffee grinder and coffee maker incredibly user friendly, it also boasts a "teach" method that you can opt for in the beginning, which eliminates the typical trial-and-error period of a new coffee maker.  And, once you have your preferred brew settings figured out, you can lock them so all unauthorized changes are prohibited.
