Question 1

Is 0.45 on a Niche Zero the same as 0.45 on a Baratza Sette 30?

Accepted Answer

No. The two grinders count in different steps, so the same number gives a different grind. 0.45 on the Niche Zero matches about 15 on the Baratza Sette 30.

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.
