Roasted Barley Malt Flour (RBM)

Roasted Barley Malt Flour, often known as RBM, is a flour made by milling roasted malted barley, also described by the manufacturer as black malt. It is a very dark brown flour with a characteristic highly roasted cereal aroma and a distinctly roasted, bitter flavour.

Its main role in baking is to add colour and roasted malt character rather than sweetness or dough activity. Used in small quantities, it can deepen crumb colour, enrich crust tone and bring a fuller roasted note to breads and other bakes where a darker finish is wanted.

Because it is strongly flavoured and highly coloured, Roasted Barley Malt Flour is best used sparingly and increased gradually to suit the style of bake. A little can go a long way, especially where you want colour support without overwhelming the rest of the recipe.

Available in 500g, 1kg and 25kg sizes, it suits both home bakers using it carefully in small amounts and bakeries using it more regularly in production.
