Who is Hendrik Kleinwächter? The Engineer-Turned-Sourdough Expert Who Wrote The Sourdough Framework
Hendrik Kleinwächter is a software engineer who turned his analytical mindset to the complex art of sourdough baking. Dissatisfied with the inconsistent results and lack of clarity in many recipes, Hendrik brought his problem-solving skills, precision, and passion for knowledge to breadmaking. His unique perspective and innovative approach have helped redefine what a bread book can be.
Hendrik’s relationship with bread began during his childhood, baking loaves with his mother. This formative experience planted the seeds of a lifelong fascination with bread. Later in life, as he became disillusioned with the quality of industrial bread, he delved deeper into the world of sourdough, finding joy in its authenticity, flavor, and tradition. He transformed his passion into The Bread Code, a YouTube channel dedicated to sourdough baking tutorials and experiments. The success of the channel inspired him to create a more enduring resource—one that would transcend algorithms and deliver timeless knowledge to a global audience.
