These Australian bread flours are suitable for making sourdough bread and are grown here in Australia. Many of them have been a regular part of my kitchen for more than a decade! None of my recommendations are sponsored.

April 12, 2023Hi 👋
I just placed an order sourdough starter kit
I did bought some high protein flour like organic stoneground white bakers flour from wholegrain millingco which is 12 percent protein can i use this flour to feed my starter? After i finish this flour can i swap to the flour that you recommend?
I found out stoneground flour are pretty corse will this cause the bread to be dense?

Thank you for your order! It’s packed and I’ll drop it at the Post Office this morning for you.
Yes you can use the stone ground flour from Wholegrain Milling. It’s not their best one for sourdough but it will work. You will notice a slight improvement next time when you use something with 12.5% or more. It won’t hurt the sourdough starter, but again it will improve with higher protein flours.
If you like the organic flours, try the same brand in their premium version of white flour: https://amzn.to/3EXvr6S
As for stone ground flours being course, I haven’t found they make much difference to the loaf. Wholegrain flours do since the large particles from the grain are not sifted out and they act like little shards that interrupt/cut the gluten strands into shorter pieces that don’t stretch as far. Hence the loaves are slightly more compact, but there are some ways of getting a good loaf from wholemeal flours too: Use 20% more water and rise the dough at a cooler temperature for longer so that the flour hydrates as much as it can
Hope this helps!
