Cold Brew Coffee Ratio Calculator

A 1:8 coffee-to-water ratio produces a smooth, medium-strength cold brew ready to drink. For concentrate (to dilute later), use a 1:4 or 1:5 ratio.

Cold brew should steep for 12-24 hours in the refrigerator. Coarse grinds need longer (18-24 hours), while medium grinds steep faster (12-14 hours). Do not over-steep or it may become bitter.

Use coarse ground coffee for cold brew. Fine grinds will over-extract and produce a bitter, gritty brew. Coarse grinds produce a smoother, cleaner flavor.
