How to Calculate Bread Hydration
Formula
Hydration % = (Total Liquid / Flour Weight) x 100
Milk is about 87% water, so multiply milk weight by 0.87. Each large egg contributes roughly 38 g of liquid (the white and yolk combined, minus the shell).
Hydration Ranges
Example Calculation
500 g of flour with 350 g of water, no milk or eggs.
- 01Total liquid = 350 + 0 + 0 = 350 g
- 02Hydration = (350 / 500) x 100 = 70%
- 03This is a moderate hydration suitable for rustic breads.
