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