Why Starter — Dealing Dough
The method

Sourdough vs. biga vs. poolish

What you're actually choosing between when you decide how to leaven your crust.

Poolish Biga Sourdough
Crust Extensible, open, more irregular crumb Tighter crumb, cleaner chew and structure Same open, extensible crumb as a poolish — plus tang and depth neither preferment reaches
Ferment 12–16 hrs, commercial yeast 12–16 hrs, commercial yeast 18–48+ hrs, wild yeast & bacteria
Upkeep NoneMix, use, done NoneMix, use, done Normally constantFeeding, every day, forever
This is the only reason kitchens skip sourdough. We feed it. You bake it. Schedule a demo

A lot of "artisan" pizza is built on biga wearing a sourdough label. Real technique, different result — you can tell it in the crust.
