What’s in the 3-Phase Sourdough Starter Guide?

In this printable one-page PDF, I’ll walk you through how to create a sourdough starter from scratch using my unique three-phase system.

Every new sourdough starter needs to go through these three phases:

  1. The False Rise
  2. The True Rise
  3. The Explosive Starter

Whether it takes you 7 days or 21 days, once your starter goes through these three phases, you’ll be able to make delicious sourdough bread with your own starter!


2026 Update: I created a different sourdough starter guide back in 2022 that shows you how to make a sourdough starter in as few as six days. That particular guide shows more of a day-by-day schedule and doesn’t explain the three-phase system. I’ll still include that older sourdough starter guide in the welcome email, just in case anyone is looking for it.
