Three stage sourdough build calculator

Three-stage sourdough build calculator

Enter the weight of the flour and water for the final amount of sourdough starter added to the recipe. The calculator will display the weights (in grams) of the three builds. At 60 - 70°F, these should be between 12 - 14 hours. The first two builds are at 125% hydration, but the final starter will match the recipe. Be sure to put back the same amount you removed from your mother starter!
