What You'll Need to Activate a Sourdough Starter


  • Quart-size glass jar
  • Non-metal stirring utensil
  • Tight-weave cloth or paper coffee filter
  • Rubber band to secure the cover to the jar


  • 1 packet dehydrated sourdough starter
  • Unchlorinated, unfluoridated water
  • Appropriate flour for your sourdough starter (check enclosed instructions)

Instructions for Activating a Sourdough Starter

  1. Add packet of starter to 1 Tbsp. flour and 1 Tbsp. of room temperature water in a quart-size glass jar and stir thoroughly. Cover the jar with a coffee filter or breathable material secured with rubber band and culture the starter in a warm place (70-80°F) for 12-24 hours.
  2. After 12-24 hours, feed the starter with an additional 2 Tbsp. of flour and 2 tbsp water. Stir thoroughly.
    • Your starter should have the consistency of pancake batter. Add flour or water to adjust as necessary.
  3. After 12-24 hours, feed the starter with an additional 1/4 cup of flour and 1/4 cup water. Stir thoroughly.
  4. After 12-24 hours, feed the starter with an additional ½ cup of flour and ½ cup water. Stir thoroughly.
  5. Discard down to ½ cup starter and then feed the starter with ½ cup water and ½ cup flour. Stir thoroughly.
  6. Repeat step 5 every 12-24 hours for 3-7 days. Do this until the starter has the consistency of pancake batter and is bubbling regularly within a few hours of feeding. That’s when your starter is activated and ready to use!


Once your sourdough starter is active and bubbly for 3 consecutive feedings, you have a few choices. You may:

  1. Prepare fresh starter for baking.
  2. Maintain starter daily at room temperature.
  3. Maintain starter weekly in the refrigerator.
