Quick rule: Bad smell days 2-5 can be normal for scratch. Bad smell after day 10 with no rise = weak culture that needs replacing.

How To Fix Vomit Smell Fast
Days 2-5 vomit smell can be normal. Keep 25g from bottom, discard rest. Don't use bleached flour.
25g starter + 50g unbleached all-purpose + 15g whole rye + 65g filtered water. Thick feeds favor good yeast.
75-80°F, feed every 12 hours for 3-4 days. Smell should turn from vomit/cheese to sour yogurt to yeasty bread.
If smell stays like vomit past day 10 with no bubbles or rise, your scratch culture lost. Start fresh with Squirrelly Girl Starter and skip the stink entirely.
People Also Ask
Why does my sourdough starter smell like vomit?
Butyric acid from unwanted bacteria during early days of scratch starter. Common days 2-5. Should fade as yeast and good bacteria take over. If it persists past day 10, culture is too weak.
Is vomit smell normal?
For scratch starters days 2-6, yes it's common but unpleasant. For mature starters it should never smell like vomit — should smell yeasty, tangy, like yogurt.
Can I use starter that smells like vomit?
Not while it smells like that. Feed until smell is sweet/yeasty and it doubles in 4-8 hours. If smell never improves, replace with mature culture.
Why does my starter smell like cheese?
Same as vomit smell — bacterial imbalance. Fix with warmer temp, thicker feeds with rye, and filtered water. Or switch to a proven mature starter.
