    Lutz Geißler

    Sourdough is a large ecosystem in a small jar.

    Lutz Geißler

    German bread pope

    A trained geologist, he discovered a passion for—and a pursuit of—perfection in bread baking. His Plötzblog is the most successful German-language bread-baking blog, and his bread-baking books have become standard references. In the online course, Lutz lets you watch closely as he shows exactly how great bread is made!

    I like the idea that I can watch these courses as often as I want. The courses inspired me to start making sourdough right away and bake different kinds of bread. I’m very happy with the results.
