25 January 2026 Infermentum's Sourdough Starter

We are delighted to announce that Infermentum has been certified by the Consortium for the Protection of Naturally Refreshed Sourdough Starter.
Founded in 2022, the Consortium for the Protection of Naturally Refreshed Sourdough Starter has a clear mission: to preserve one of humanity's great baking traditions, sourdough starter.

THE INFERMENTUM SOURDOUGH STARTER

Sourdough starter is created from a simple mixture of flour and water, which ferments naturally under carefully controlled temperatures and humidity levels. This process is driven by naturally occurring microorganisms, including lactic acid bacteria such as Lactobacillus and Acetobacter, together with yeasts from the Saccharomyces family, which develop in a naturally balanced relationship.

The sourdough starter in our bakery is like an old friend. We care for it with dedication and affection. It has grown alongside us, accompanying us from our very first experiments. It is the result of a journey shaped by continuous learning, evolving techniques and the combination of different starters. Every step has deepened our understanding of this remarkable ingredient. It has taught us how to create fragrant, easy-to-digest baked goods made with carefully selected ingredients.

Today, it is the heart of every recipe and flavour combination we create, whether inspired by tradition or reinterpreted in our own way, always with enthusiasm and humility. If you'd like to take a look behind the scenes of our bakery and discover how our soft handmade panettoni are made, click here.

Sourdough starter is a living ingredient with its own character. It reacts to the other ingredients in unexpected ways, which means it must be cared for, observed, tested and managed every day. Often, it means starting over with humility and curiosity. Experience teaches us how to understand its development, allowing us to create truly exceptional handmade baked goods.

The handmade products certified by the Consortium are:

This certification confirms that we are moving in the right direction. We are proud of the recognition awarded to our sourdough starter, a fundamental element in achieving the softness and distinctive flavour that define our handmade panettoni, handmade colombe and every naturally leavened desserts in our bakery.
