Not SourEnough.

The bread tastes fine but could be any loaf. There's no distinctive tang, no complexity. It could have been made with commercial yeast. It tastes like nice white bread.

§ 01 — what you're seeing The symptom.

Pleasant bread. Mild flavor. Some yeasty notes. But no distinctive sourdough character — no tang on the finish, no complexity from long fermentation. If this is what you wanted, great. If you wanted San Francisco-style sourdough, this isn't it.

§ 02 — root causes Why it happened.

Ranked by likelihood. Start at the top before assuming something exotic.

  1. most common
    No cold retard
    Baking the same day after a short final proof produces the mildest flavor. Acidity develops over time, especially in the cold — which is why an overnight fridge proof is the single biggest tool for increasing sourness.
  2. common
    Too fast fermentation
    A warm kitchen with an active starter can move through bulk fermentation in 4–5 hours. There's not enough time for the bacteria to produce significant acidity. Speed is the enemy of tang.
  3. common
    100% white flour
    Whole grains — especially rye — contribute fermentation speed and flavor. An all-white loaf will always be milder than one with 10–20% rye or whole wheat.
  4. occasional
    Young starter
    A starter under 6 months old hasn't yet built the complex microbial community that produces nuanced acidity. Older starters tend to produce more complex, consistent sourness.
§ 03 — fix this bake What you can do right now.
  1. Nothing for this bake
    You can't add sourness after baking. Enjoy the mild loaf as is — it's still good bread. Plan for more tang next time.
§ 04 — next bake How to prevent it.
  1. Add a cold retard
    After shaping, put the dough in a floured banneton, cover tightly with plastic wrap, and refrigerate overnight — 8 to 16 hours. Bake straight from the fridge. This single change produces the biggest jump in sourness.
  2. Extend bulk fermentation
    Let it go a full hour longer at room temperature. More time = more acid. Watch for overproofing — use the poke test before shaping.
  3. Add 10–15% rye flour
    Replace 10–15% of your white flour with whole rye. Rye adds fermentation activity and a noticeably earthy, tangy flavor. It also improves crust color.
  4. Use a stiffer starter
    Reduce your starter hydration from 100% to 65–80%. Stiffer starters favor acetic acid production — the sharp, vinegary tang. A small change in starter hydration has a meaningful effect on flavor.
  5. Extend the cold retard even longer
    Push the cold retard from 12 to 24 hours if your schedule allows. The longer the cold ferment, the more acetic acid develops. The loaf will be noticeably sharper.
