The Grindmaster GNB-21H Grind'n Brew dual bean decanter grinderbrewer is ideally suited for any commercial location, especially those where an airpot server would be beneficial.  Grind coffee beans and use it to brew your coffee instantly for the freshest coffee possible with an aroma that will draw the customers in for more!

Not only do you not have to take up the space of both a coffee maker and a coffee grinder, this particular Grindmaster GNB-21 grinder and brewer is particularly compact at just 9.5" wide.  Even the tightest spaces have 9" to spare, and you'll be able to keep your counter space open and free for the rest of your immediate needs!

The PrecisionBrew technology used by Grindmaster in this coffee grinder with coffee maker is digitally controlled and so precise that it will actually regulate and control the water tank temperature to stay within +/- just 1 degree of the optimum brewing temperature.  It also has a Low Temp/No Brew feature that prevents the brewer from brewing until the proper temperature has been reached.

Pulse Brewing
The GNB-21H Grind'n Brew offers a pulse brewing/pre-infusion process that allows the user to program not only the number of pulses but also the pulse-on time and the pulse-off time.  This can increase extraction by as much as 20%.

Because this Grindmaster coffee grinder and coffee maker is so precise, you'll want to ensure that your settings stay untouched.  This is incredibly easy thanks to the programming lock-out that locks out anyone unauthorized to change settings.  It also has a built-in bean counter and a front control panel that's clear and easy to use.
