Keeping Your Sourdough Starter Alive
A healthy starter is a reliable companion that responds to your rhythm in the kitchen. Once you establish a routine, the maintenance becomes as instinctive as brewing morning coffee.
Consistency beats perfection
Your starter will be more forgiving than you expect. Aim to feed it before it develops a dark, thin layer of liquid on top, which indicates it has fully consumed its previous meal.

What goes in.
- 50gmature sourdough starter
- 50gall-purpose or bread flour
- 50gfiltered water at room temperature
Ratio-based feeding
Always discard down to a small base amount before adding fresh flour and water. This prevents the volume from growing out of control and ensures the new culture has plenty of fresh fuel.
The method.
Discard
Remove all but 50 grams of your starter from the jar. You can save the discarded portion for pancakes or crackers, or simply compost it.
Feed
Add 50 grams of flour and 50 grams of water to the jar containing your base. Use a clean spatula to incorporate every streak of dry flour into the mixture.
Clean
Scrape down the interior walls of the jar to keep the glass clear. This helps you monitor the rise and avoids crusty build-up.
Ferment
Cover loosely and leave at room temperature until the mixture has doubled in size and looks bubbly, typically 4 to 8 hours depending on your kitchen's temperature.
Other turns to take.
The Cold Pause
If you bake once a week, keep your jar in the refrigerator. Feed it once, let it sit out for two hours to jumpstart, then refrigerate. Feed again just before you plan to bake.
When it doesn't go to plan.
If your kitchen is cold, find a spot inside a turned-off oven with the light on to keep the culture active.
Use filtered or bottled water if your tap water is heavily chlorinated, as chlorine can inhibit wild yeast.
A hungry starter will eventually grow a layer of 'hooch'—a dark, grey liquid. Pour it off or stir it in; it is harmless but indicates the starter needs a fresh feeding.
The ones that keep coming up.
How do I know if my starter has gone bad?
Healthy starter smells like yogurt or sweet vinegar. If you see fuzzy, colored mold on the surface or it smells like rotting fruit or cheese, discard it and start fresh.
Can I use different types of flour?
Yes. Rye or whole wheat flour will make your starter more active, while white flour is more predictable and gentle.
