Grinder Adjust Guide

Background

Adjusting the grinder is one of the key elements in achieving the right extraction of a brew.

This is true for all styles of coffee brewing.

General Rules

Important Note: The grinder adjusts value is an index number. All grinders are individual. A value from one grinder to another, or one machine to another, is not directly comparable. Each machine is individual and the number is just for reference.

Coarser = faster pour = less extraction

Finer = slower pour = more extraction

You have to imagine that the key driver is the time in which the water is in contact with the grounds.

A way to control that is the particle size of the grounds.

Grinder 1 and 2

TopBrewer Pro's have 2 grinders. Compact models have 1. 

	Pro	Compact
Grinder 1	Left grinder	Primary grinder
Grinder 2	Right Grinder	Not used

Greater number = finer*

Lower number = coarser

*You can maximum adjust finer 10 steps in one go.

How to adjust

Adjusting the grinder on all TopBrewer's (built after 2013) is done like this:

1. ↑ on the keypad until display shows ADJUST
2. Hit Yes
3. ↑ until display shows GRINDER
4. Hit Yes
5. Grinder 1 is shown
6. Toggle ↑ or ↓ to find Grinder 1 or 2
7. Hit Yes on the grinder you would like to adjust
8. ↑ or ↓ to adjust. 
   1. ↑ = finer
   2. ↓ = coarser
9. Hit Yes to store the new setting. The grinder is now adjusting.
10. Test 2-3 drinks and note final result. Repeat process if necessary.

Adjusting correctly

There's a lot to say about adjusting a machine correctly. There's a lot of variables. More so, than I can cover here in this article.
