Fed vs Unfed Sourdough Starter

By : | 0 Comments | On : April 18, 2025 | Category : Bread, Recipes, Sourdough

Have you ever found yourself staring at your sourdough starter, wondering if you really need to feed it before baking? Or maybe you’ve been tempted to skip a step and just see what happens? Well, I put that curiosity to the test—and the results may surprise you.

In my latest video, I baked two loaves of sourdough bread side by side: one made with a freshly fed, active starter, and the other made with an unfed (aka dormant or sluggish) starter pulled straight from the fridge. No pre-feeding, no coaxing—just straight into the dough.

To keep things fair, I used the exact same recipe, flour, salt, water, and fermentation times for both loaves. The only difference? One loaf had a lively, bubbly starter that had been fed a few hours earlier, and the other used a cold, unfed starter that hadn’t seen flour in over 24 hours.

This experiment was not only fun—it was kind of eye-opening. Sometimes, baking “rules” are more flexible than we think. If you’re a sourdough baker who’s ever forgotten to feed your starter, don’t panic—you might still end up with a pretty great loaf.

Let me know in the comments: have you ever baked with an unfed starter?

Sourdough Bread

  • 310g of water
  • 100g of healthy strong fed or unfed starter
  • 460g of bread flour
  • 11-12g of salt
    1. Throw everything into a stand mixer and mix on low until it’s well combined. Move to an oiled vessel with a loose lid. 
    2. Set a timer for 30 minutes. At the end of 30 minutes perform stretch and folds. 
    3. Now repeat steps 2 for a total of 5 stretch and folds (or 2 1/2 hours total).
    4. Place dough with loosely covered lid in a warm place with no drafts and bulk ferment until the dough has risen about 30%. For reference it takes about 5 hours at 80 degrees.
    5. Sprinkle flour on the top of the dough and turn out onto a clean counter.
    6. Stretch your dough in all directions then roll up like a cinnamon roll. Turn the roll 90 degrees and roll using the tuck and tug method. For bread shape: Seal your ends then pull dough towards you to tighten the top. For boule shape: do not seal ends, instead pull the dough towards you in a circular motion hiding each end as you create tension. 
    7. Allow dough balls to rest for 5-10 minutes. If they stay in the shape you’ve given them without flattening to a pancake, then you are ready to move on. If they flatten out too much, do another rough or two of shaping, following step 7 again.
    8. Place seam side up in floured banneton and cover loosely. Place in refrigerator for 6-12 hours but up to 36.
    9. Preheat your oven to 450F before you get your bread out of the refrigerator
    10. Turn your cold dough out onto a piece of parchment and score. Place scored loaf into the bread pan of your choice, your Dutch oven, or right onto a preheated baking stone.
  1. Mist your loaf with water and cover. Bake 30 minutes covered then remove the cover and bake another 20-30 minutes or until the desired color is achieved. 
  2. Cool on a baking rack before cutting.
