Keeping Your Sourdough Starter Active
Your starter is a living culture that relies on consistency to thrive. Whether it lives on your counter for daily baking or in the back of the fridge for weekend projects, the ratio of flour to water is the heartbeat of your sourdough.
Consistency is your primary ingredient
Use a kitchen scale for every feeding. Relying on volume measurements like cups will lead to imbalances that eventually weaken the culture.

What goes in.
- 50gmature starter
- 50gunbleached bread flour or whole wheat flour
- 50gfiltered water (room temperature)
Why discard matters
Removing a portion of the starter prevents the colony from becoming too large to feed effectively and keeps the acidity levels in check, ensuring the yeast remains active rather than dormant.
The method.
Weigh the starter
Place your clean jar on the scale and add 50 grams of your mature starter. Discard the rest or save it for another recipe.
Add fresh feed
Pour in 50 grams of room temperature water and 50 grams of flour. The consistency should resemble a thick paste.
Mix thoroughly
Use a spatula to scrape the sides of the jar down, ensuring no dry flour remains. The surface should be smooth.
Mark and monitor
Place a rubber band around the jar at the current level of the starter. This lets you track how much it grows as it feeds.
Other turns to take.
Refrigerator Maintenance
If you bake once a week, feed the starter, let it sit for two hours at room temperature to jumpstart activity, then move the jar into the fridge to slow the process down.
When it doesn't go to plan.
If you see a dark liquid on top (hooch), your starter is hungry and needs to be fed more frequently.
Use a straight-sided jar; it makes it much easier to judge if the starter has doubled in volume.
If your house is cold, place the jar near the oven or in a cupboard to keep the yeast happy.

Can I use chlorinated tap water?
Most starters tolerate standard tap water well, but if you have highly chlorinated water, let it sit out for an hour before mixing to allow the chemicals to dissipate.
How do I know if my starter has gone bad?
A healthy starter smells like yeast, fruit, or vinegar. If you see pink or orange streaks, or if it develops a persistent smell of rotting meat, discard it and start fresh.
