Dough that won’t rise usually means the yeast is struggling — either from temperature, age, or moisture issues.
Common causes
- Old yeast
- Water too hot or cold
- Room too cold
- Not enough kneading
1. Old yeast
Expired yeast won’t activate.
Quick fixes:
- Test yeast in warm water + sugar
- Replace if no bubbles appear
2. Wrong water temperature
Hot water kills yeast; cold slows it.
Quick fixes:
- Aim for warm, not hot
- Use a thermometer if unsure
3. Cold room
Yeast works slowly in cold air.
Quick fixes:
- Place dough in a warm cupboard
- Cover with a damp cloth
What to try first
Test the yeast — it tells you instantly if it’s alive.
When to start again
If the dough hasn’t risen after 2–3 hours.
