What Is Hydration?

Hydration is simply the ratio of water to flour by weight. A 65% hydration dough has 650g of water for every 1000g of flour.

Low Hydration (55-60%)

Firm, easy to handle. Good for Roman tonda, thin crust styles.

Medium Hydration (62-68%)

Balanced. Classic Neapolitan range. Good for beginners.

High Hydration (70%+)

Wet, sticky, requires skill. Creates open, airy crumb. Ideal for focaccia, teglia, Detroit.
