5 from 2 reviews

Get a jump on your sourdough bread with kombucha, milk kefir, water kefir or jun. Using a yeast-based culture will result in a vigorous starter in just 24 hours. Perfect for anyone struggling to make traditional sourdough bread.


  • 2 oz flour (or 1/2 cup depending on flour)
  • 2 oz fermented beverage (1/4 cup -see section above for options)


  1. Mix equal parts (by weight) of flour and a fermented beverage in a glass container.
  2. Loosely cover with tea towel and leave in a warm spot. Above the fridge works well.
  3. Stir vigorously every 12 hours until ready to use. Leave it for at least 24 hours, and up to 72 hours (3 days).


  • The best beverages to use are either milk kefir or an unflavoured kombucha. Don’t include the actual SCOBY or grains. The fermented liquid will have enough yeasts and bacteria to kick start the sourdough starter. However, avoid using off-the-shelf grocery store kefir and kombucha. They usually don’t contain  active strains of yeasts.
  • Most sourdough bread recipes require a 100% hydration ratio for the starter. (Meaning equal portions of water and flour by weight.) This is easiest to do with a digital scale (affiliate link) that has a zeroing function. If you have to measure the ingredients by volume then remember that whole grain flour is heavier than white flour.
  • This quick sourdough bread method will work for gluten free recipes as well! Just use a gluten free bread flour mix and GF bread recipe.
  • See section above for information on how to feed and maintain this type of sourdough starter.
