The Sourdough Framework Hardcover Book

Sound Familiar?

Your loaves come out flat and dense, no matter what recipe you follow

You have no idea if your starter is actually ready to bake with

Every loaf is different and you can't figure out why

Recipes say "until it looks right" but you don't know what "right" looks like

Skip 2 Years of Trial and Error

The hard way

  • 100+ hours of YouTube with conflicting advice
  • 50+ failed loaves at $4 each = $200+ in flour
  • 2 years of "what went wrong this time?"
  • Trying random tips without understanding why

The shortcut

  • One book. One framework. Complete picture.
  • Understand the WHY, not just the steps
  • Diagnose problems yourself
  • Weekend of reading years of knowledge

$50 and a weekend vs. 2 years of frustration

Perfectly shaped sourdough dough ready for proofing

What If You Actually Understood Why?

Most recipes tell you what to do. This book teaches you why it works.

Once you understand the science behind fermentation, you stop following recipes blindly. You start making decisions. You adapt to your flour, your climate, your schedule.

That's when bread becomes fun.

  • Wake up to dough that's perfectly proofed, not over or under
  • Know exactly when your starter is ready to bake
  • Get consistent oven spring and that satisfying ear
  • Actually understand what went wrong when a loaf fails

Typical recipe book:

"Bulk ferment for 4 hours"

The Sourdough Framework:

"Here's how to read your dough and know exactly when it's ready, whether that's 3 hours or 6 hours in your kitchen"

Once you understand fermentation, you'll never blindly follow a recipe again. You'll adapt any recipe to your flour, your climate, your schedule.

Hendrik Kleinwächter
About the Author

Hi, I'm Hendrik

I'm a software engineer who spent 10 years obsessively reverse-engineering bread. I've made every mistake, run countless experiments, and documented everything.

I approached sourdough the way I approach code: systematically. Why does this work? What variables matter? What can I control?

The result is this framework. Not opinions. Not "this is how grandma did it." Just science you can apply in your kitchen.

Fix Problems Yourself

Flowcharts and troubleshooting guides help you diagnose flat loaves, dense crumb, or weak oven spring.

Starter Confidence

Independently collected via Judge.me on shop.the-bread-code.io

25 years baking, still learned heaps

"I've been making bread for 25 years, and sourdough for at least 5, but I still picked up heaps of useful hints, and inspiration to try out new things. This has seriously raised my game. My family are all very impressed."

Ulrich Roxburgh Verified buyer · June 2025

Decades of baking, finally understood

"I have been baking bread for the family for decades, learned from my grandmother. My sourdough breads have always been rather mediocre. Hendrik's analytical approach has given me insights I have never previously understood and my sourdough breads are now the absolute favorite of the family."

Brad Burlew Verified buyer · August 2024

The sourdough bible

"The author has tried everything and tells you what does and doesn't work and why. The flowcharts are brilliant and makes the entire process easy to follow."
