Biga or poolish: the differences and when to use them

Biga and poolish are two preferments: prepared in advance, left to mature, then added to the final dough. They add flavour, aroma and digestibility.

What biga is

A stiff preferment (44–45% water), usually matured 16–18 hours at ~18 °C. Intense flavour, robust structure, needs strong flour.

What poolish is

A liquid preferment (100% water); the yeast is set according to maturation hours. Delicate aroma, soft crumb, easier to handle.

The differences in short

When to use each

Biga if you want character and have strong flour; poolish if you want lightness and a more forgiving method. Both beat a straight dough.
