Learn sourdough

What this path is for #

This path is for a home baker who wants more than a sourdough checklist. It starts with the culture and flour, then follows the dough through mixing, fermentation, shaping, and baking. The order matters because each stage changes what you can observe at the next one. Calvel’s professional baking account is a technical companion for the relationship between flour, fermentation, and dough handling; it is not a universal home timetable ¹.

By the end, you should be able to explain what sourdough is, read a formula in baker’s percentages, recognize a dough that is gaining gas and strength, and choose a next adjustment when the loaf is too dense, slack, pale, or sour. The companion Bread books: a working library helps you choose between Robertson’s focused country-loaf method, Leo’s visual home-sourdough teaching, and Owens’s grain- and season-aware repertoire ^{2 3 4}.

How to use the sequence #

Work these pages in order the first time. The path moves from identity to mechanism to hand skill:

1. Name the system. Sourdough, flour, starter, and fermentation establish what is in the dough and what the words mean.
2. Build the dough. Mixing and dough development show how flour, water, salt, and folds become a structure that can hold gas.
3. Read time through the dough. Bulk fermentation and final proof are separate stages. Look for volume, bubbles, elasticity, aroma, and surface tension instead of treating a clock as proof.
4. Make the result testable. Divide, pre-shape, shape, score, and bake turn the mechanism into a loaf you can inspect when it cools.

The Country loaf (teaching formula) is the practice lab. Its weights make the flour basis, hydration, and inoculation visible; its method lets you test those relationships while remembering that one formula responds to every kitchen’s flour, temperature, and timing.

If the loaf is not behaving #

Start with the symptom, not a new recipe. A dense loaf often sends you back to starter strength, flour, or bulk fermentation. A slack dough may point to temperature, hydration, inoculation, or fermentation running too far. A pale loaf asks about heat and steam as well as proof. Use Sourdough troubleshooting to separate what can still be corrected from what should simply be recorded for the next bake.

After the first pass, follow whichever connection answers your next question. Wheat flour can take you to wheat, gluten, and milling; Fermentation can take you to cheese, wine, and preserving. The path is a suggested order, not a requirement. When you want current hands-on bread practice in San Francisco, use the focused practice bridge.

When you want weights, use the teaching Country loaf (teaching formula). When you want a city bakery as context, open Tartine Bakery. When you want the civic myth and the 1971 microbiology, open San Francisco sourdough.
