The Story of Vitus

The journey of Vitus began in 2017, when German journalist

and sourdough enthusiast Martina Goernemann brought her struggling starter to the Sourdough Library. With the help of Karl De Smedt, the

Sourdough Librarian, she revived it — and named it Vitus.​

Martina then traveled with Vitus across Europe and the US, chronicling the experience in her book Sourdough: Four Days to Happiness.

Along the way, Vitus was fed with beer, spelt flour, honey, and maple syrup — evolving into a truly unique culture.​In

Nobleboro, Maine, artist John Whalley was so inspired by Vitus that he painted it in a piece titled “Bread of Life” — likely the first and only painting in history dedicated to a sourdough starter. The artwork features Vitus surrounded by bread, an old Bible, and a wooden barrel, painted using the traditional Flemish egg tempera technique.

​Today, Vitus is owned by Puratos and lives on as the Friendship Sourdough — used to teach people how to bake and connect through fermentation. It’s a sourdough that doesn’t just rise — it inspires
