Which flour is the best?

Are you a UK baker? Marriages flour is excellent, I use it at times. I  mostly use Shipton Mill, as I buy in bulk 25kg sacks for the organic white and also cake flour, but you don't have to buy in bulk sacks. Ken Forkish, Emmanuel Hjiandreou and Richard Bertinet all recommend them in their books, as does Michel Roux in his pastry book. I also use some Bacheldre Mill flour and Claybrooke Mill. The Shipton Mill is the best value, but they are all lovely flours.

Must have some interesting choices!

Depends on the type of bread you want to bake and what is available.  

I would ask locally from a baker or bread baking instructor (who's bread you would like to emulate.)  Maybe even purchase flour thru them.  

I thought it might be the UK as Marriages is one of the best readily available brands here. If you can get hold of that you will be fine.

Actually you can get KA flour from Citysuper but it s so expense 

I buy flour from wholesaler ( 25KG package ) 

The cheapest are from China , Japan flours are most popular and in mid range , Flour from the West are most expensive. I am using Japan flours but really wanna try flour from Eu   

BTW I just "TAOBAO" some french flour from China haha

Some bread made with Japan flours

Besides, protein content of flours from 759 are too high for Eu-style breads.

You can find some 11% protein content Japan flours from baking shop.

What breads do u wanna make?

Actually, I will buy flours of 25Kg package from wholesaler and I am finding someone to share the flours. U can contact me if u are interested. It is so much cheaper (30% at least) !

 I live in California and previously put together a list of U.S. wheat flour brands and their protein content. I am also attempting to put together a list of U.K. retail Wheat Flour. The data for this incomplete list is from UK supermarket websites and the protein / gluten data comes from nutritional labels posted on the supermarket websites (usually given as protein grams per 100 grams of flour)

If you have additional information to add, please post it and I will include it in this list.
