Quick diagnosis: A quiet starter may be cold, underfed or newly establishing. Activity must be judged with aroma, rise and time—not bubbles alone.
What the Symptoms Tell You
Volume remains flat, aroma is weak or sharply unpleasant, and feeding produces little visible gas.
Why This Usually Happens
The most common causes are connected to temperature, ratio, timing, ingredient condition or technique. Compare the dish with these specific checks:
- Temperature was too low or feeding intervals unsuitable.
- Starter was diluted with an extreme feeding ratio or weak flour.
- Chlorinated water, contamination or neglect damaged the culture.
Professional Rescue Method
- Retain a small clean portion and feed at a consistent measured ratio.
- Keep at a stable suitable temperature and observe across several cycles.
- Restart completely if mould, pink, orange or putrid signs appear.
Safety and Quality Limit
Discard any starter with fuzzy mould, pink or orange colour, rotten odour or foreign contamination. Do not taste uncertain starter raw.
Prevent It Next Time
- Use clean containers and repeatable weights.
- Mark level and record temperature and feeding time.
- Maintain a schedule suited to room or refrigerator storage.
Chef’s Verification Test
After feeding, it should rise predictably and smell cleanly acidic before being relied on for bread.
