The No-Fail Sourdough Starter Guide
Every sourdough starter that "died" on someone was really just neglected past its window of forgiveness. A starter is a stable ecosystem of wild yeast and lactic acid bacteria, and stable ecosystems are surprisingly hard to kill — you just have to stop working against them.
Day 1–3: Patience
Mix 50g whole rye flour with 50g room-temperature water in a jar. Loosely cover. The bubbles you may see on day 2 are not yeast — they're leuconostoc bacteria throwing a brief, smelly party. Ignore them. Do not feed yet.
Day 4–7: The quiet phase
Discard half, feed 50g flour + 50g water daily. Around day 5 the jar goes suspiciously quiet. This is where most people give up. Don't — the pH is dropping, selecting for the organisms you actually want.
Day 8+: Liftoff
When the starter doubles within 6–8 hours of feeding and smells like yogurt and green apples, it's ready. Name it something embarrassing. Mine is called Clint Yeastwood.
- Too sour? Feed more often, keep it warmer, use a smaller inoculation.
- Gray liquid on top? That's "hooch" — harmless, just hungry. Stir it in or pour it off.
- Going on vacation? Refrigerate it. It survives weeks of neglect at 4°C.
