Wild thing, you make my loaf spring

The ninth month of the year is when the Real Bread Campaign goes on a mission to help everyone worldwide to discover that: life’s sweeter with sourdough!

Launched in 2013, the aims of #SourdoughSeptember are to:

  • Share the delicious delights of genuine sourdough
  • Encourage more people to bake genuine sourdough
  • Create a showcase for small, independent bakeries that bake genuine sourdough
  • Help people to say no to sourfaux and avoid paying a premium for something that simply isn't the real deal
  • Encourage people to join and/or donate to the Real Bread Campaign 

Mother mother, take me where life's sweeter

What's going on?

Across thirty days of sharing food, facts and fun, Real Bread bakeries, baking schools, mills, food festivals and other fermentalists around the globe run sourdough classes, tastings, feasts and more to help everyone experience and enjoy the power of sour.

This year will see a rise in online sourdough classes, workshops and other virtual get-togethers.

Find and ADD details of events on the...

Real Bread Campaign events calendar

NB Events are often added to the calendar much closer to (and during) September. Many organisers don't add the details at all, so keep an eye on social media, local press and the mailing list of your favourite local Real Bread bakery, baking school etc.


A special focus for 2021 is encouraging people who’ve been buying from local indie bakeries (or got the bready baking bug*) during the pandemic to keep doughing.

Since March 2020, we've welcomed a huge surge of people around the world starting (or resuming) love affairs with sourdough bread, some baking or buying it for the first time. Meanwhile, many Real Bread bakeries have reported experiencing a surge in demand for theirs.

Sourdough September builds on this passion, encouraging people who’ve only tried one type of bread made using a sourdough starter to buy or bake others.

*Well, cultures of lactic acid bacteria and yeast cells…

Sourdough social

Sourdough bread is made by people of almost every age, nationality, ethnicity, gender identity, (dis)ability, religion and culture in the world.

YOU can join the fun with many thousands of people around the planet by tagging your (relevant) social media posts with #sourdough, #SourdoughSeptember and us:

Twitter: @RealBread
Facebook: @RealBreadCampaign
Instagram: @RealBreadCampaign

Then, if applicable, add:

#SourdoughSelfie if it's a photo of yourself making sourdough, or holding a loaf of genuine sourdough bread you've baked or bought from a Real Bread bakery. Remember, as it's a selfie, we want to see YOU in these photos!

#WeAreRealBread if you are one of the people behind the rise of Real Bread. Whether farmer, miller, baker or baking teacher, please help the world see you to help celebrate the diversity (in all senses) of our supporters and other companions.

If you'd be happy for us to publish your photos (either of yourself or of others with their permission) please email them to

We need high resolution photos that are:

  • Landscape / horizontal (rather than portrait / vertical) at least 1200 x 800 pixels (see articles in our news and features pages to see what we mean) OR
  • Square at least 1000 x 1000 pixels

...and we'd love to see and share photos of whole Real Bread bakery teams, famlies baking together, online and real world classes of sourdough students...

Business owners

How might YOU help share sourdough secrets and demystify the delicious delights of the oldest way of raising a loaf?

Ideas for events/activities you can organise include:

  • Give away (or make a small charge for) pots of sourdough starter
  • Showcase a different sourdough bread on your menu each week and offer tasters
  • Run a sourdough baking class or Q&A / troubleshooting session
  • Organise a social event for people who've attended one of your sourdough baking classes in the past
  • Join forces with a local brewer, charcutier, pickler and cheese maker to: run a feast of fermentation, create a local food box for people to order online, or lay a fermented food trail between your shops

Login to add details of your event/activity to the Real Bread calendar

The earlier you add your event, the better your chance of us giving it a mention on our press release and other media work…

Not right for you?

Then how about something else instead? We've created the hook and do promotional work at an international level. What you hang on it (in line with the initiative’s aims) to use the opportunity of free publicity and drive custom for your Real Bread business is up to you.

If face-to-face events / activities aren't permitted where you are (or aren't right for you this year) how about running something (eg a baking class or social event) online instead?

Support our charity's work

Adding a optional suggested donation (eg 50p-£1) to Sustain, the charity that runs the Real Bread Campaign, onto customers’ bills would be amazing, please!

What is sourdough?

Sourdough isn’t a look, flavour or style. Any bread that can be made with baker’s yeast (and many more) can be made using a sourdough starter.

While it's becoming increasingly fashionable, sourdough is no fad - it's the oldest way of leavening a loaf.

At its simplest, genuine sourdough is made using just three ingredients: flour, water and salt. Using this holey trinity, novice home bakers and true artisans alike can nurture the yeasts and bacteria naturally present in flour to foster a thriving sourdough starter culture, whose microbial magic makes the dough rise.

Sourdough September revels in this amazing alchemy, celebrating the crafting of these (optionally plus other natural) ingredients into delicious, nutritious Real Bread.

September is also a time for everyone to say no to sourfaux

Say no to sourfaux!

It is both flattering and frustrating that some supermarkets and industrial loaf fabricators have spotted the increasing appetite for sourdough made by Real Bread bakers, and decided they want a slice of the action.

Sadly, what they are producing is not always genuine sourdough.

The 'ingredients' industry is busy concocting 'easy' and 'quick' packet mixes that try to replace time, skill and quality ingredients with a litany of flavourings, acidifiers, additives, commercial yeast and allsorts.

Read labels, ask questions
Whenever you buy a sourdough loaf, it's worth asking how it was made and with what - genuine sourdough is made using a live sourdough culture (aka a starter or leaven) but NOT any of the following:

  • Baker's yeast
  • Dried sourdough powder
  • Sourdough concentrate
  • Yoghurt, vinegar, or other acidifier
  • Flavourings, preservatives and other additives

Baked products made using such things are what we call sourfaux and Real Bread Campaign cofounder Andrew Whitley calls pseudough.

Protection from misleading use of the word sourdough is included in our call for An Honest Crust Act.

If you have seen something sold under the name 'sourdough' that you just know isn't, take a photo of the ingredients list and the marketing claims and post them on social media using the #sourfaux hashtag.
