A baker's grade organic strong white flour, milled by Matthews in the Cotswolds from certified organic wheat. Matthews have supported organic farming for over 30 years and keep their organic wheat separate from the rest of the mill.
For sourdough
At around 11.5 to 12% protein this is a moderate-strength white that suits long, slow fermentation, and it gives enriched doughs a soft crumb. It is a good everyday flour for a standard sourdough loaf and for feeding a starter.
For a wetter dough and a more open crumb, the Matthews 100% Canadian at 14.5% has more strength. For more flavour, blend in some organic stoneground wholemeal.
Folic acid
This flour is fortified with folic acid, which UK law requires in most white wheat flour from December 2026. Matthews are updating their packaging, so some bags may not list it yet. If you would rather bake without it, see our flour with no added folic acid.
