Questions
Is 0.7.4 on a 1Zpresso K-Ultra the same as 0.7.4 on a Wilfa Svart?
No. The two grinders count in different steps, so the same number gives a different grind. 0.7.4 on the 1Zpresso K-Ultra matches about 6 on the Wilfa Svart.
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.
