The Matthews regenerative stoneground strong white, the organic stoneground wholemeal flours from Matthews and Marriage's, the stoneground dark rye and the stoneground wholemeal spelt. They are all in our no added folic acid collection, and each product page says which group it is in.
The UK Bread and Flour Regulations were changed so that non-wholemeal wheat flour must be fortified with folic acid, at 250 micrograms per 100g, by 13 December 2026. Most white flours now have it added. Wholemeal flour is exempt, the rules cover wheat rather than rye, and Matthews do not add it to their stoneground flours. Some bags may not list folic acid yet while mills update their packaging.
Start with a strong white bread flour of 12% protein or more, such as the stoneground strong white or Marriage's finest strong white. For a wetter dough and a more open crumb, the 100% Canadian has more strength. Adding 10 to 30% wholemeal, rye or spelt brings flavour, and a little rye in your starter feed tends to make it livelier.
