Maintaining a sourdough starter is easy with this simple daily or weekly feeding schedule.



  • 25 grams mature starter
  • 100 grams filtered water
  • 100 grams unbleached flour


  1. Add the ingredients to a clean jar, stir vigorously and cover lightly, allowing the starter to “breath”.
  2. Daily Maintenance: Feed the starter once a day, pick morning or evening, and allow to set at room temperature until the next feeding.
  3. Weekly Maintenance: In the morning take the starter out of the fridge and allow to come to room temperature. Feed the starter and let sit on counter for a few hours or until right before bed. Store in the fridge until the next feeding.


  • Any unbleached flour can be used to feed your starter.
  • Make sure water is free of chlorine which can disrupt or potentially kill the yeast and bacteria in the starter.
