Starting and Maintaining Sourdough Culture
Building a starter requires patience more than precision. You are creating an environment for naturally occurring microbes to flourish, and that process relies on the rhythm of your kitchen rather than a clock.
Consistency is your main ingredient.
Your starter will not be ready to bake with on day two. Wait for the culture to show a vigorous, dome-like rise consistently before attempting to use it in dough.

What goes in.
- 50gWhole rye or whole wheat flour
- 50gFiltered water, room temperature
Maintaining balance
Discarding half of your starter before feeding ensures you do not end up with gallons of culture and keeps the acidity level manageable so the yeast stays active.
The method.
Mix the initial batch
Combine 50g whole grain flour and 50g water in your jar. Stir until no dry pockets remain. Cover loosely and let it sit in a warm spot for 24 hours.
The daily rhythm
Discard all but 50g of the mixture. Add 50g of all-purpose or bread flour and 50g water. Stir thoroughly to incorporate oxygen.
Observe the signs
Look for small bubbles and a faint, slightly sour smell. If you see no activity after 48 hours, keep feeding once daily until it begins to move.
Confirming readiness
When the starter reliably doubles in volume within 4 to 6 hours of feeding and smells like mild vinegar or yogurt, it is ready to leaven bread.
When it doesn't go to plan.
Use a rubber band around the jar to mark the level after feeding so you can track how high it rises.
If a dark liquid forms on top, it is hungry; pour it off and feed the starter as usual.
Whole grain flours contain more nutrients and will accelerate the initial fermentation compared to white flour.
The ones that keep coming up.
Does the type of water matter?
If your tap water has a strong chlorine scent, let it sit in an open container for an hour before using it to let the chlorine dissipate.
How do I store it if I am not baking daily?
Once established, keep it in the refrigerator and feed it once a week.
