- When to feed before baking.
- How to avoid feeding too early or too late.
Quick Answer
A room-temperature starter is commonly fed every 12–24 hours depending on temperature and feeding ratio. A mature starter kept in the fridge can often be fed around once a week, or refreshed before baking. Feed according to the starter’s rise-and-fall cycle rather than blindly following the clock.
This lesson is part of our Sourdough Starters section: “Learn how to care for the heart of every loaf.”
Feeding at Room Temperature
A starter kept on the counter ferments continuously. In a warm room it may peak and become hungry within half a day; in a cooler room it may take much longer. Your schedule should reflect its normal peak.
Feeding a Starter in the Fridge
Refrigeration slows fermentation, so an established starter can be maintained with far less frequent feeding. Many home bakers refresh it before or after a weekly bake rather than feeding daily.
Feed the Starter, Not the Clock
If a starter has barely begun fermenting, feeding again can be premature. If it peaked many hours ago and smells strongly alcoholic, it may have gone too long. Learn the pattern in your own jar.
How Often to Feed Before Baking
If your refrigerated starter is strong, one or two room-temperature refreshes may be enough before baking. A neglected starter may need several feeds.
How Feeding Ratio Changes Frequency
A 1:1:1 feed generally peaks sooner than a larger 1:3:3 feed at the same temperature because there is less fresh food relative to the starter population.
A Practical Weekly Routine
For occasional bakers, keep a small starter in the fridge, refresh it before baking, build only the amount you need, then return a small portion to cold storage.
From Our Workshop
We encourage people to keep less starter than they think they need. A smaller culture is cheaper to maintain, creates less discard and is easy to build up before baking.
Bake Slower Tip
Write down the feed time and peak time for three or four feeds. That simple record becomes your personal starter schedule.
Common Mistake
Do not assume ‘feed every 24 hours’ works in every kitchen. In warm weather that can be too slow; in a cold kitchen it can be too fast.
Today You Learned
- Countertop starters need more frequent feeding than refrigerated starters.
- Temperature strongly affects feeding frequency.
- Larger feed ratios usually take longer to peak.
- Use the rise-and-fall cycle to guide feeding.
- A small fridge starter is efficient for occasional baking.
Frequently Asked Questions
Should I feed my starter once or twice a day?
Either can work. Frequency depends on temperature, ratio and starter activity.
Can I feed straight from the fridge?
Yes, but allow time for the starter to warm and become active before baking.
Do I need to feed it every week in the fridge?
Weekly is a practical routine for many bakers, though a strong starter may tolerate longer.
Should I feed immediately after it peaks?
You can, but you do not need to catch the exact minute.
Can I skip a feeding?
Usually yes with an established starter, especially if refrigerated.
Need the Right Starter Setup?
Accurate scales and a clear jar make feeding patterns much easier to understand.

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.
