A simple, foolproof 7-day plan to create a bubbly, active sourdough starter from scratch using just flour and water. Perfect for beginners, this guide builds confidence one feeding at a time.

Ingredients

  • Unbleached all-purpose flour (60 grams per feeding)
  • Filtered or tap water, room temperature (60 grams per feeding)
  • Whole wheat flour or rye flour (optional, for sluggish starters)

Instructions

  1. Day 1: In a clean glass jar, combine 60 grams of unbleached all-purpose flour with 60 grams of room temperature water. Stir until no dry flour remains. Scrape down sides, cover loosely with a towel or coffee filter, and place in a warm spot (70-75°F). Let sit for 24 hours.
  2. Day 2: Check for tiny bubbles or a watery layer. Discard about half (60 grams) of the starter. Add 60 grams of flour and 60 grams of water. Stir, scrape sides, cover, and let sit for 24 hours.
  3. Day 3: Expect more bubbles and a sour, yeasty smell. Discard half (60 grams). Feed with 60 grams of flour and 60 grams of water. Stir, cover, and wait 24 hours. If no bubbles, use whole wheat flour for this feeding.
  4. Day 4: Starter should be noticeably bubbly and may double in size. Discard half (60 grams). Feed with 60 grams of flour and 60 grams of water. Stir, cover, and let sit for 24 hours. If sluggish, move to a warmer spot.
  5. Day 5: Starter should reliably double in size within 12-24 hours. Discard half (60 grams). Feed with 60 grams of flour and 60 grams of water. Stir, cover, and let sit for 24 hours. If doubling quickly, start feeding twice a day.
  6. Day 6: Starter should be very active, doubling in 6-8 hours. Discard half (60 grams). Feed with 60 grams of flour and 60 grams of water. Stir, cover, and let sit for 12 hours. If feeding twice a day, do a second feeding 12 hours later.
  7. Day 7: Starter is ready when it doubles in 4-8 hours, has a domed top, and passes the float test. Discard half (60 grams). Feed with 60 grams of flour and 60 grams of water. Wait 4-6 hours, then use in your favorite sourdough recipe.

Notes

Temperature matters: keep starter at 70-75°F for best results. Don’t skip the discard step—it balances the yeast-to-food ratio. The float test is a good indicator but not foolproof. If starter smells like acetone, it’s hungry—feed it more often. Starter is resilient; even if it seems dormant, warm feedings can revive it.
