How to adjust the grind size in a manual grinder

Proper grind size is one of the most important steps that makes a difference in the taste of coffee. Many people own excellent grinders, but the problem lies in the grind itself, not in the beans or the tool. If the grind is too fine, the taste often comes out bitter or overly heavy. If it's too coarse, the extraction is poor, and the taste is weak or overly acidic.

If you are looking for a suitable grinder for distillation, you can check out the manual grinder.

To see the method practically, step by step, watch the video on adjusting the grinder size.

Why is adjusting the grind size important?

The grind size directly affects the speed at which water passes through and the extraction of flavors from the coffee. Therefore, even a slight change in grind can noticeably alter the result in your cup.

The finer the grind:

The water is delayed further
Increased extraction
A bitter or dry taste may appear

The coarser the grind:

Water flows faster
Extraction decreases
A mild or sour taste may appear

How to adjust the grinding size

In most manual mills, the method is as follows:

Turn the dial or pointer to the right until it locks completely.
Then move to the left side with the appropriate number of clicks.
Start with a medium level, then adjust according to the preparation method and taste.

If you want to apply the method to the same product directly, you can visit the manual coffee grinder page.

What is a suitable temperature for distillation?

For distillation such as V60, many start with 26 to 29 clicks as a suitable starting point, and then adjust according to the result.

If you notice that:

The coffee is brewing too quickly and the taste is weak: grind it a little finer.
The coffee is taking too long and tastes bitter: grind it a little coarser.

To understand the adjustment more clearly, watch the video tutorial on adjusting the grind size.

How do I know I've reached the right grind?

The correct measurement depends on 3 things:

Extraction time
Coffee drip pattern
Final taste

If the extraction is balanced and the taste is clear and without unpleasant bitterness or sharp acidity, you are close to the right grade.

Is the same grind suitable for all types of coffee?

no.

The type of coffee beans, roast level, humidity, and even the filter used can all affect the ideal brewing level. Therefore, it's best to start with a known level and then adjust slightly until you achieve the best result.

Important tips when adjusting the grind

Don't edit randomly every time
Change only one or two degrees
Try the same amount of coffee and water
Record the appropriate score for each recipe
Start with a known strength, then adjust according to taste.
