Sourdough Academy

Your friendly, zero-judgment guide to creating life from flour and water. Follow these steps, trust the process, and you'll be baking in a week.

Course Curriculum

  1. Day 1: Overview

    We are not just making bread; we are cultivating a microscopic ecosystem.

  2. Day 2: Tools

    Precision beats intuition in the beginning. Measure everything.

  3. Day 3: The Spark

    A simple mixture awakens the dormant life on the grain.

  4. Day 4: The Silence

    It looks dead, but a microscopic war is raging inside.

  5. Day 5: The First Feed

    The acidic environment is set. Now we feed the yeast.

  6. Day 6: The Routine

    Sourdough is a pet. It needs regular meals to survive.

  7. Day 7: The Strengthening

    Consistency creates capability.

  8. Day 8: Graduation

    Your starter is alive — but give it 7-14 more days of daily feeding before expecting a reliable rise in bread.

  9. Day 9: The Formula

    Mathematics is the language of consistency.

  10. Day 10: Temperature

    Temperature is an ingredient.

  11. Day 11: The Levain

    The son becomes the father.

  12. Day 12: Build Levain

    Wake up the workforce.

  13. Day 13: The Peak

    Catch the wave before it crashes.

  14. Day 14: Autolyse

    Passive strength building.

  15. Day 15: Enzymes

    Biology does the kneading for you.

  16. Day 16: The Mix

    Uniting the trinity: Flour, Water, Biology.

  17. Day 17: Slap & Fold

    Aggressive organization.

  18. Day 18: Gluten

    The invisible scaffolding.

  19. Day 19: Stretch & Fold 1

    Reviewing the structure.

  20. Day 20: Coil Fold 2

    Gentle strength.

  21. Day 21: Final Fold 3

    Final organization.

  22. Day 22: Bulk Fermentation

    The main event.

  23. Day 23: The Jiggle

    Knowing when to stop.

  24. Day 24: Pre-Shape

    Building tension.

  25. Day 25: Final Shape

    The envelope.

  26. Day 26: Oven Spring

    The final explosion.

  27. Day 27: Preheat

    Heat saturation.

  28. Day 28: The Score

    Controlled explosion.

  29. Day 29: The Bake

    From dough to bread.

  30. Day 30: The Crumb

    Reading your results.

  31. Day 31: Mastery & Beyond

    The first loaf is just the beginning of a lifelong conversation with grain, water, and fire.

Starter FAQ

Whole rye carries more wild yeast spores on the bran and roughly twice the amylase enzyme content of refined flour. Both accelerate the first 72 hours of fermentation.

One teaspoon of lemon juice drops the pH to roughly 4.0–4.3. This acidic window suppresses unwanted bacteria like Leuconostoc and Klebsiella while lactic acid bacteria (LAB) and wild yeast adapt safely.

No. A dramatic Day-2 rise is almost always a Leuconostoc gas burst — bacteria producing CO₂, not the wild yeast you want. The activity will collapse by Day 3. Keep feeding.

Usually no. Cool temperatures (below 22 °C) can double the timeline. Move the jar to a warmer spot (oven with light on, top of fridge) and continue daily feeds. Mould or pink streaks would be a problem; slow is not.

A 7-day starter is alive but rarely strong enough for a reliable loaf. Most artisan bakers wait 10–14 days — bake when it doubles within 4–6 hours after feeding for two consecutive days and passes the float test.

Nothing irreversible. The starter becomes more acidic, may collapse, may grow hooch (a grey liquid alcohol layer). Stir, discard most of it, feed normally. Skipping one feed during the 7-day build delays maturity by about a day.

Discard is the portion you remove before each feed to keep the volume manageable and maintain a healthy flour-to-starter ratio. From Day 4 onward, discard tastes mildly sour and works beautifully in pancakes, crackers, and waffles. Day 1–3 discard goes to the bin — it has not stabilised yet.
