Questions

Is 39 on a DF DF64 Gen 2 the same as 39 on a Hario Mini Mill Plus?

No. The two grinders count in different steps, so the same number gives a different grind. 39 on the DF DF64 Gen 2 matches about 7 clicks on the Hario Mini Mill Plus.

How accurate is this conversion?

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.

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

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