Seventy-five percent hydration is not a rule — it is a starting conversation between flour and water. Bread flour absorbs differently than whole wheat, rye drinks more than white. Dial your dough, not someone else's recipe.
Hydration Calculator
Salt at 2% flour weight. Starter at 20% for standard 8–10hr bulk at 24°C.
Bulk fermentation is not a clock — it is a temperature equation. At 24°C your dough reads differently than at 18°C. The same starter, the same hands, a two-hour swing in ambient temperature: that is the difference between an open crumb and a dense one.
Bulk Fermentation · Temperature Chart
Cold kitchen, slow acid development — complex flavour
Ideal for beginners, forgiving window
Standard bulk — watch for 50–75% rise
Fast ferment, tighten your observation
Danger zone — check every 30 minutes
Target 50–75% volume increase. Poke test: dough springs back slowly, retains slight indent.
The blade is the last conversation before the oven. A single arc at 30 degrees becomes the ear — the caramelized ridge that tells you the loaf opened exactly where you asked it to. Scoring is not decoration. It is pressure management written in crust.

Single Ear
30° blade angle. One decisive arc from north to south. The classic batard ear.
Forty pages of bulk fermentation charts, hydration tables by flour type, a full scoring reference, and a starter troubleshooting guide — the document we wish existed when we started.

"The first time I held a loaf that opened the way I intended — not by luck but because I understood the fermentation — was the moment I stopped being a person who bakes bread and started being a baker."
A starter is not an ingredient. It is a colony — billions of organisms with hunger, rhythm, and memory. Feed it at the same hour each day and it will learn your schedule. Neglect it and it will tell you, in acid and collapse, exactly how long you were away.
Starter Maintenance · 7-Day Protocol
50g whole rye + 50g water (28°C). Mix until no dry flour. Cover loosely. Leave at 24°C. Nothing will happen. That is correct.
