Few things bring comfort quite like the smell of freshly baked sourdough bread. Tangy, crusty, and deeply satisfying, sourdough has earned its place as a beloved staple in kitchens around the world. National Sourdough Day is a delicious celebration of this naturally fermented bread — its rich history, health benefits, and the hands-on joy of baking it from scratch.

What is National Sourdough Day?

National Sourdough Day is an annual celebration dedicated to the heritage and flavor of sourdough bread. It’s a day for bread lovers, bakers, and foodies to come together and honor the centuries-old art of sourdough fermentation. From traditional techniques to modern twists, this day shines a light on one of the most iconic and versatile breads in the world.

When is National Sourdough Day?

National Sourdough Day is celebrated every year on April 1. In 2026, it falls on a Tuesday, offering the perfect midweek opportunity to bake, break, and share bread with friends, family, or your online foodie community.

How to Get Involved

Whether you’re a seasoned baker or a curious beginner, here are some great ways to join the celebration:

  • Start a Sourdough Starter: Mix flour and water and begin your own fermentation journey — no yeast packets needed!
  • Bake and Share: Make your favourite sourdough recipe and share it with neighbours, coworkers, or online.
  • Host a Sourdough Swap: Exchange homemade loaves or starters with fellow bread enthusiasts.
  • Take a Class: Join an online or local sourdough baking workshop to refine your technique.
  • Celebrate the Science: Use this day to explore the fermentation process and teach others about the beneficial microbes behind sourdough’s unique flavour.

History of the Event

While sourdough itself dates back thousands of years, National Sourdough Day has more modern roots in the growing appreciation for traditional baking methods and home-cooked nourishment. It gained popularity during the home baking boom of the early 2020s and has since become a recognised occasion for celebrating craftsmanship in baking, culinary heritage, and community sharing.
