Understand the “why” behind every loaf.

For the baker who has moved beyond recipes — the enzymes, the wild yeasts, the lactic acid bacteria, and the dance between them that creates flavor and structure. The science of sourdough, distilled onto one beautifully crafted A2 poster.

// what_it_covers

The science, made visual

Fermentation, explained

What enzymatic activity is truly responsible for a perfect crust, crumb and rise.

Yeast vs bacteria

The intricate dance between wild yeasts and lactic acid bacteria — and who does what.

Flavor & structure

How time, temperature and microbes combine into the taste and texture you love.

For the “why?” baker

Why a starter behaves differently on a warm day — first principles, not folklore.
