Sour Flour

Danny Gabriner's first business model was a little odd: he wanted to bake 1,000 loaves of bread, and give them all away. It turned out to be a winning proposition, though, charming friends, neighbors, and strangers into supporting his newly proposed bakery, Sour Flour. In addition to crafting artisanal breads, Danny saw Sour Flour's mission incorporating education, whether it came through teaching people to appreciate good bread with a free loaf or instructing them in the process of baking some of their very own.

While he still doesn't operate out of a formal brick and mortar location, Danny shares the fruits of his labor in breadbaskets across the city. He sticks to his philanthropic roots, too, spearheading Bagel Monday at La Victoria Bakery, in which bakers gift fresh, free bagels to all comers. Classes at La Victoria are taught by Sour Flour Breaducator Cat Shimizu, who teaches students how to care for their wild yeast starter, bake rustic loaves, and figure out when a crust is ready to molt.


The starter workshop was awesome and lots of fun!

The bread was absolutely delicious, and with the clear instructions Kat emailed after the class, I am ready to make sourdough bread of my very own!
