Question 1

Is 10 clicks on a Porlex Mini II the same as 10 clicks on a Niche Zero?

Accepted Answer

No. The two grinders count in different steps, so the same number gives a different grind. 10 clicks on the Porlex Mini II matches about 0.45 on the Niche Zero.

Question 2

How accurate is this conversion?

Accepted Answer

It is a starting point. Both grinders are mapped to particle size in microns, fitted from the Honest Coffee Guide charts for each brew method, not from manufacturer burr-gap specs. Beans, roast and burr wear change the result, so adjust by taste.

Question 3

The coffee tastes sour or bitter after converting. What should I change?

Accepted Answer

Sour and thin: grind finer by a step or two. Bitter and harsh: grind coarser. Change one thing at a time.
