Baratza Maestro Plus Conical Burr Coffee & Espresso Grinder

  Product Description

  The Maestro Plus™ is based on the very popular Maestro™ grinder.  The Maestro Plus™ includes all the winning features of the Maestro™, plus some extras that increase its versatility and ease of use.  The Maestro Plus™ includes a 60 second timer, a front mounted pulse button and a brushed-satin metal base.  The Maestro Plus™ has double the weight of the Maestro™ which gives it a rock-solid feel and increased stability.
The original Maestro Plus™ was introduced in 2004.  In March 2007 it was upgraded to include an innovative calibration system, new powerful DC motor and other improvements. (5)

  Product Features

German made conical burrs
The Maestro Plus™ uses the same 40 mm conical burrs it has always used.  Conical burr grinders are exceptional at producing consistent grinds from very fine to very coarse. 
Grind Coffee for Any Brewing Method
There are many coffee grinders on the market.  However, few have the ability to grind fine enough for a professional espresso machine and coarse enough for a French press coffee maker.  The Maestro Plus™ has 40 steps of adjustment.  Choose the perfect setting by turning the bean hopper to the desired position.
Innovative calibration
Commercial grinders have a calibration system to ensure that the grinder will grind fine enough for espresso and has the range to grind coarse enough for press pot.  Now this feature is available in a grinder designed for home use.  An innovative burr calibration system ensures that each grinder has the full range of grind.  The grinders are calibrated when they are manufactured to ensure an accurate range of grind.  If necessary the grinders can be user calibrated.
DC Motor
A 240 watt DC motor is replacing the current AC motor.  The DC motor is twice as powerful as the current motor and turns slowly resulting in cool, quiet operation and permits long grinding duty-cycles.  The circuitry is equipped with an automatically resetting, thermal cutoff switch.
Special Gear Reduction
The Maestro Plus™ uses a combination of gear and electronic speed reducers to slow the spinning of the burr to 450 RPM.  This slow speed reduces heat, noise, and static generation in the grinder. It also ensures that the beans feed smoothly into the burrs. 
Timers switch and Pulse button
The Maestro Plus™ has a sixty second timer, with segmented graphics, for easily repeatable grind times.   It also has a front mounted pulse button that manually controls the on/off function.  This is nice if you wish to grind a small amount of coffee for espresso.
Pulse button makes Espresso Easy
If you have an espresso machine, you will enjoy the convenience of being able to grind directly into the filter basket for your machine.  After you remove the coffee grounds bin, you can insert your filter basket (portafilter) directly under the dispensing chute to collect the coffee as it is being dispensed.  You can push the pulse button with your thumb while holding the filter basket for true one hand operation.
