Save precious counter space without sacrificing quantity or variety in your coffee serving with a Grindmaster B-3 Precision Brew 3 warmer digital coffee maker that measures just 8.25" across.

The PrecisionBrew feature that's included with the B-3 coffee maker is truly one of Grindmaster's most renowned features.  With the capability to hold the water temperature to within +/- 1 degree of the optimal temperature, you can be assured the most accuracy and consistency possible in your brewing.  It also has a low temp feature that will not allow brewing to begin until the proper temperature has been reached.

Cycle Counter
Never lose track of how many cycles you brew, thanks to the built-in cycle counter of the Grindmaster B-3 coffee maker.  You'll be able to run your business more efficiently with an accurate daily record.

Programmable Warmers
Save energy by programming the warmers of this Grindmaster digital coffeemaker to turn off any time within 240 minutes after the last brew cycle finishes.

Three Warmers
While it's almost a must that you have two warmers for regular and decaf in any commercial setting, why not take your coffee serving up one more level and offer your customers a third specialty choice?  Take advantage of three warmers to have three varieties on hand at any moment, with no wait time!
