About Sourdough September
There is nothing quite like the aroma of a freshly baked loaf of bread pulling you into the kitchen, especially when that bread boasts the complex, tangy depth of a traditional sourdough.
Every year, from September 1 to September 30, food lovers and bakers around the globe unite for Sourdough September. Launched in 2013 by the Real Bread Campaign, this month-long celebration honours the ancient craft, science, and sheer joy of natural fermentation, while encouraging everyone to discover why life is sweeter with sourdough.
The core mission of the month is to celebrate genuine sourdough and support the independent bakeries that keep the tradition alive. In a world full of mass-produced bread, Sourdough September shines a spotlight on the dedication it takes to tend a living starter.
It is also an educational movement, helping consumers spot the difference between the real deal and "sourfaux"—mass-produced loaves that use artificial flavourings, commercial yeast, or yogurt to mimic the tangy taste without undergoing the slow, beneficial fermentation process.
Sourdough September Traditions and Customs
The customs of Sourdough September revolve heavily around community, education, and getting your hands floury. Throughout the month, artisan bakeries, culinary schools, and local businesses host hands-on workshops to demystify the baking process.
Experienced bakers often participate in starter giveaways, sharing portions of their own mature "mother dough" with beginners to help them launch their home-baking journeys.
On social media, the community comes alive under the hashtag #SourdoughSeptember. Home bakers and professionals alike share time-lapse videos of their dough rising, photos of beautiful scoring designs, and tips for achieving the perfect open crumb structure.
Many independent cafes and pizzerias also join in by introducing limited-edition sourdough items to their menus, celebrating the versatile nature of wild yeast.
Did you know? Sourdough is ancient. The oldest physical evidence of leavened bread dates back to around 1500 BC in Ancient Egypt, where wild yeast fermentation was discovered by chance.
Did you know? Some sourdough starters are decades or even centuries old. During the Great San Francisco Earthquake of 1906, Louise Boudin famously risked her life to save her bakery's original "mother dough," a culture that is still used to bake bread today.
Did you know? Sourdough acts as a natural prebiotic. The long fermentation process breaks down wild starches and phytic acid, making the nutrients more bioavailable and the bread significantly easier on your digestive system.
How to Get Involved in Sourdough September
Whether you are a seasoned pro or have never touched a bag of flour, there are plenty of delicious ways to participate this month. Here is how you can jump in:
Skip the supermarket aisle and buy your loaves directly from a small, independent neighbourhood bakery that crafts authentic, long-fermentation bread.
Mix equal parts flour and water in a clean jar and feed it daily. Within about a week, you will have a bubbly, active wild yeast culture ready for baking.
Sourdough isn't just for sandwich loaves. Use your starter or leftover "discard" to make delicious homemade pizza crusts, crackers, pancakes, or pretzels.
Gift a jar of your active starter to a neighbour, bake a extra loaf for a friend, or post your kitchen successes online using the official campaign hashtags to inspire others.
