Baratza Maestro Operation Manual - Setting The Grind Control:

Initial Operation:

Place the Maestro Grinder on a level surface.  Insert the plug into a 

120V AC outlet.  Remove the lid from the hopper by lifting off.  Pour the 

desired quantity of roasted whole coffee beans into the hopper up to a 

maximum of 8 oz.  Replace the lid.  Ensure the ground coffee bin is fully 

inserted.

Setting the Grind Control:

Slowly rotate the bean hopper 

clockwise or counter clockwise 

to align the indicator on the bean 

hopper with the desired number 

setting on the grind scale.  Select 

the correct grind for the brew pro-

cess you are using.  40 grind set-

tings are available.  The settings 

shown in the table below can be 

used as a general guideline. The actual grind size for a particular setting 

will vary depending on many factors, including: degree of roast (light vs. 

dark), freshness, humidity, type of bean, oil content, etc. With use, you 

will determine the setting that is right for your taste, brewing style and 

your favorite beans.

Note: Partially ground coffee beans may remain between the burrs 

after the grinder is turned off, adjusting the grind may be easier 

when the grinder is running.
