“Very coarse” is a different number on every grinder. These are worked out from each model’s own dial curve rather than a generic chart.

How cold brew works

Without heat, extraction happens slowly and selectively. Many of the compounds responsible for perceived acidity and bitterness are extracted far less readily cold, which is why cold brew tastes rounder and sweeter than the same coffee brewed hot.

The trade is time. Twelve to eighteen hours is typical, and the ratio above makes a concentrate meant to be diluted roughly one to one with water or milk.

Coarse grind matters more than it looks. Over a twelve-hour steep, fines will over-extract and add the muddiness cold brew is supposed to avoid.

When it tastes wrong

Sour or thin

Steep longer, or grind slightly finer.

Bitter or harsh

Steep less, grind coarser, or dilute more.

The common mistake

Grinding at filter size because the bag suggested it. Cold brew wants the coarsest setting your grinder has; the long steep does the work that a finer grind would do in a hot brew.
