Heirloom bread flour?

Toast

Has anyone heard of a mill that makes bread flour out of an heirloom grain like Red Fife?

That depends where you live, I expect! I know you can buy Anita's Organic Red Fife flour in Western Canada, for example.

You can buy some Turkey at Heartland Mill, either whole wheat or bolted, and then sift it more finely.

Ok, Take KA bread flour in the blue package, or, say Pillsbury "Better for Bread" that my mom used for years. How are those flours different from a bolted whole wheat flour? I've read in several places that you can't do that (make bread flour) at home.
