What each input means

Concentrate Volume (mL): Total volume of cold brew concentrate you want to make.
Strength: Coffee-to-water ratio for brewing. Concentrate is stronger and meant to be diluted before drinking.
Serving Dilution Ratio: Parts water (or milk) to 1 part concentrate when serving. 0 = drink straight, 1 = equal parts.

How this is calculated

Identify Input Parameters
Concentrate Volume (mL) = 1000, Strength = 1, Serving Dilution Ratio = 1 = 3 input(s) provided
Calculate Coffee Needed
125 = 125
Calculate Water Needed
875 = 875
Calculate Steep Time
Steep Time = 16
16 = 16
