Graham flour Graham flour Graham flour is a type of coarse-ground whole wheat flour named after Sylvester Graham. It is similar to conventional whole wheat flour in that both are made from the whole grain, but graham flour is ground more coarsely and is not sifted during milling (i.e. unbolted). A report from 1913 claimed that bread made from graham flour had a protein content of 12.1% – only slightly less than white wheat flour and essentially the same as whole wheat flour. Graham flour is available at health food stores, some grocery stores, bakery supply stores, and some specialty and gourmet
Flour lowest in gluten protein content, with 6-7% (5-8% from second source) protein to produce minimal binding so "the cake crumbles" easily. Pastry flour has the second-lowest gluten protein content, with 7.5-9.5% (8-9% from second source) protein to hold together with a bit more strength than cakes, but still produce flaky crusts rather than hard or crisp ones. All-purpose, or "AP flour", or plain flour is medium in gluten protein content at 9.5-11.5%(10-12% from second source) protein content. It has adequate protein content for many bread and pizza bases, though bread flour and special 00 grade Italian flour are often preferred
