Grind

What it is and what sets it apart: Grind isn’t a universal number across grinders—it’s relative. Includes overall setting and fines quality. Fine/medium/coarse are method ranges.

How it’s used or measured: Finer raises extraction/slows flow; coarser opposite. Change one click and taste. Log setting + grinder in Brew Lab.

Flavours and cup impact: Right grind: sweetness and clarity. Too fine: bitter/stall/channels. Too coarse: sour/weak.

Technical notes: Espresso ≪ filter ≪ press typically. Prefer burrs.

Common mistakes: Copying another grinder’s number. Grinding days ahead. Changing grind and ratio together.
