What You’ll Learn
- Why hooch forms.
- What colours are typical.
- Whether to stir it in or pour it away.
- How to prevent frequent hooch.
- How to distinguish hooch from contamination.
Quick Answer
Hooch is a liquid that can collect on or within a hungry sourdough starter. It may be clear, grey or brown and often smells alcoholic. You can pour it off or stir it back in before feeding. Hooch is different from pink, orange or fuzzy contamination.
This lesson is part of our Sourdough Starters section: “Learn how to care for the heart of every loaf.”
What Is Hooch?
Hooch is liquid produced during fermentation, often appearing when a starter has exhausted much of its available food.
What Colour Can It Be?
Clear, grey and brown shades are common. The exact appearance depends on flour and storage.
Should You Pour It Away?
Either approach is acceptable. Pouring it away can produce a milder starter; stirring it in retains more acidity and flavour.
Why Does Hooch Keep Appearing?
The starter may need more frequent feeding, a larger feed, cooler storage or refrigeration.
Hooch in a Refrigerated Starter
It is especially common after longer fridge storage and does not automatically mean the culture is dead.
Hooch vs Mould
Hooch is liquid. Fuzzy growth, pink or orange staining are not hooch and should be treated as contamination.
From Our Workshop
Hooch looks dramatic, which is why people often assume the starter is ruined. In reality, it is usually one of the easiest starter problems to fix.
Bake Slower Tip
If hooch appears repeatedly on the counter, change the schedule rather than simply scraping it off every day.
Common Mistake
Do not call every dark mark mould. Look at whether it is liquid, fuzzy growth or coloured staining.
Today You Learned
- Hooch usually means the starter is hungry.
- Clear, grey or brown liquid can be normal.
- You can stir it in or pour it off.
- Frequent hooch suggests the feeding routine needs adjustment.
- Pink, orange and fuzzy growth are different.
Frequently Asked Questions
Can I drink hooch?
No. Treat it as part of the starter, not as a beverage.
Does hooch mean the starter is dead?
No.
Why is hooch dark?
Flour type and oxidation can affect colour.
Should I feed immediately?
Usually yes if the starter is clearly hungry.
Can hooch form underneath the starter?
Yes, liquid can sometimes separate within the mixture.
Need the Right Starter Setup?
A clear jar makes it much easier to tell ordinary separation from a genuine contamination problem.

A simple starter check
Keep one variable stable while you diagnose the starter. Record the flour, feeding ratio, room temperature and approximate rise after each feed. A short three-feed record is usually more useful than changing flour, ratio and temperature all at once.
