Sourdough Bread

Facts

Safety

• No significant acute-hazard risk factors documented for standard sourdough bread-baking — the process concludes with a high-temperature bake, which is independently pathogen-inhibitory regardless of the fermentation stage's own safety profile. Safe-practice guidance:
  (a) maintain starter hygiene (clean vessel, regular feeding) — a neglected/contaminated starter can develop off-odors or surface mold (visually/olfactorily detectable, actionable discard signal) rather than posing a silent hazard;
  (b) liquid ("hooch") separation on a healthy starter is a normal sign of hunger, not spoilage, and is distinguished from true mold contamination (fuzzy, colored patches) — the same category of mold-discrimination judgment call as kombucha and koji, though at comparatively lower stakes given the terminal bake step.

Method

Sourdough Bread (Levain-Leavened Wheat Loaf)

• Active sourdough starter (a living LAB + wild-yeast co-culture, maintained by periodic feeding) — ~100 g, illustrative
• Wheat (or rye) flour — 500 g
• Water — ~350 mL, illustrative (hydration is a texture choice, not a safety control)
• Salt — ~10 g, illustrative (flavour and fermentation-rate control here — unlike the vegetable ferments, salt is not the preservation mechanism in bread)

1. 1

   Step 1

   Maintain the starter: feed it flour and water on a regular schedule until it reliably doubles and smells pleasantly sour — an underfed starter simply won't leaven.

2. 2

   Step 2

   Mix the active starter into the flour and water; hold before adding salt if you want an autolyse rest.

3. 3

   Step 3

   Add the salt and work it through the dough.

4. 4

   Step 4

   Bulk ferment at room temperature, folding periodically, until visibly risen and aerated — the LAB acidify while the wild yeast leavens via CO2.

5. 5

   Step 5

   Shape the dough and place it in a banneton or lined bowl.

6. 6

   Step 6

   Proof until ready (at room temperature, or overnight refrigerated for a slower, more sour result).

7. 7

   Step 7

   Bake hot, ideally in a covered vessel for the first part of the bake to trap steam.

8. 8

   Step 8

   Cool fully on a rack before cutting — the crumb is still setting as it cools.
