Bake beautifully light and crusty gluten-free sourdough with our White Gluten-Free Sourdough Bread Flour, specially formulated for naturally fermented bread.
Made exclusively for Sourdough Mate in Melbourne by Wild Sourdough, this high-protein flour contains 11% protein and 15% prebiotic fibre to help create better structure, rise and texture in your gluten-free sourdough.
The result is a lighter, more cohesive crumb and beautifully crisp crust — without the dense, crumbly texture often associated with gluten-free bread.
Coeliac Australia-endorsed, plant-based, low GI and FODMAP friendly, this is the flour we use in our gluten-free sourdough kits.
🌻 High-protein gluten-free flour for sourdough
At 11% protein, this flour is formulated to help gluten-free dough develop better structure and hold its shape during fermentation.
That means you can achieve a better rise, lighter crumb and more cohesive loaf than you might expect from ordinary gluten-free baking flour.
It's not simply a gluten-free flour substitute — it's formulated specifically for sourdough fermentation.
White or Wholemeal Gluten-Free Sourdough Flour?
Choose White if you prefer a lighter, more traditional-style sourdough with a soft, cohesive crumb and crisp crust.
Choose Wholemeal if you prefer a more wholesome, rustic-style loaf with a richer flavour and wholegrain character.
Both are specially formulated for gluten-free sourdough baking and endorsed by Coeliac Australia.
Please note:
This flour is not the same as Gluten-Free 1:1 All Purpose Plain Flour which is best suited to muffins, cakes, pancakes, waffles or yeasted breads.
Frequently Asked Questions
Frequently Asked Questions
What makes this gluten-free flour different for sourdough?
Most gluten-free flours simply aren’t designed for sourdough baking — which is why so many people struggle with flat, dense loaves.
Our blend is carefully formulated to behave more like traditional bread flour, making sourdough baking not only possible, but reliable.
- High protein (11%) — Rare in gluten-free flour, helping improve structure, rise, and overall texture
- Designed for fermentation — Supports a healthy, active sourdough starter and proper dough development
- Improved structure and texture — Instead of dense or crumbly results, you’ll achieve a lighter, more cohesive crumb that holds together.

How is this gluten-free sourdough flour different from supermarket gluten-free flour?
Most supermarket gluten-free flours are made for quick baking like cakes or muffins — not the slow fermentation needed for sourdough. They often include additives that can interfere with starter activity and the growth of beneficial bacteria and natural yeast, making it much harder to achieve a strong, well-risen loaf.
In short, this flour is purpose-built for gluten-free sourdough — not just a general baking substitute.
If you're a reliable gluten-free plain flour substitute that is also endorsed by Coeliac Australia Gluten-Free 1:1 All-Purpose Flour

A first time sourdough baker and this gluten free flour blend has made it simple and easy for me. All of my sourdough loaves have been perfect! Continuous repurchase.
I bought this for my daughter for Mother’s Day…she had trouble with the starter, but she emailed the company & they were so helpful straight away! She is now obsessed with making sourdough! Thank you…happy family.
As a coeliac and mother of 2 coeliacs I have been putting up with unpalatable gluten free bread for 30 years. Husband bought me the gluten free sour dough kit for Christmas. What a game changer. Since that first purchase I have been using the gf sourdough bread flour.Always get consistent results in taste. The only variable is human error but the gf flour mix is very easy to use and gives great results.
This kit is amazing!! I have now made 3 loaves, 1 for a friend who is Celioc and she said its the best GF bread ever
I am really impressed with the quality of the kit and have just baked my first loaf. Needs a little tweaking but I’m quite happy with the sourdough, both fresh and toasted.
Arrived on time and been using it constantly since so easy to follow instruction and makes the most amazing bread in taste and texture thank you Sourdough Mate
Sourdough is certainly something to master! I received my GF kit a week ago and immediately activated my starter flakes and started to feed. Made my first loaf a few days later but it was a flop literally. I asked the SD mate support group and received instant help to better support my starter and managed to get perfect growth. My dough proved amazingly, cooked beautifully in my 20yr old Dutch oven but unfortunately stuck to the bottom! I am about to try my third batch with all the lessons learnt and am excited to continue learning on this sourdough journey. The instructions and videos on the SD mate site are excellent and the support from the FB support group is spot on!
Great product! Enjoying the process
And now I can. Sourdough Mate is a game changer. My bread is beautiful. It tastes great, the baguettes are so tasty. As a ex chef, gluten free bread had broken me. I tried so many of them - nothing worked. Gluey lumps of blech!
I have messed up one batch - i used a pullman tin - wet and awful, totally my error - the baguettes from the same dough were perfect, so next time I will levain in the baneton and try again! My starter is so easy to keep alive- nice and liquid feeds every so often, and it is happy.
Going to try crumpets this weekend.
So happy to have bread that tastes and feels so good - thanks Sour Dough mate!
So easy, particularly with the easy to follow instructions. My starter has gone crazy so definitely many more loaves/ baked goods to be made here!! Thanks Sourdough Mate!!
I have just made my second loaf. It is a craft that I'm looking forward to continue.
Great instructions online and face book group.
I’ve really enjoyed learning the process and so far had 3 delicious loaves of gluten free sourdough
I recently purchased the Sourdough Mate GF starter kit and it’s been great. I’ve made half a dozen loafs of GF sourdough and it’s the best GF bread I’ve had! I even give it to my husband have it and he has no idea that it’s GF!!!
I loved following the videos and making the starter. It was one step at a time and my first loaf was fabulous. Love making GF bread at home.
I was so excited to start our gluten free sourdough journey. With 2 coeliac children it was disappointing to buy expensive glugy bread. The gluten free kit will be a game changer for us.
Got the kit and 2 days later the first loaf out of the oven was perfect.
Great instructions and video guides made it very easy.
I am sure there are failures to come but very happy so far!
I bought the GF starter kit for Christmas as a family gift.
We've never made sourdough before, but with the tools in the kit, and the really clear instructions, videos, and recipe online, we had success with our very first attempt.
My coeliac daughter is excited to have delicious bread again.
Thanks, Sourdough Mate!
I recently had some delicious GF vegan sour dough bread from a boutique bakery in another state which I cannot source locally
I was a desperate woman!
It gave me the taste and made me determined to master my own bread, especially as finding any GF bread without egg white is like finding a unicorn
My daughter and I have now become obsessed with all things sourdough
The GF kit was amazingly simple to use, the online instructions are clear and easy to follow, and the baked bread is divine!
I love that there aren’t 500 ingredients in the flour blend and they’re not highly refined
I would absolutely recommend this product
I sat on the fence for months before purchasing the GF option. Now I don’t know why I waited. I have now made a few loaves with no fails and currently have a gf fruit loaf just about ready to put in the oven. Best investment I’ve made in my gluten free journey.
Great recipe and support
Easy to follow instructions with videos of each step.
Finale results is amazing, already baked 3 loaves, the whole family love it. 😊
