@Tai Chi,
You can make sour doughs with half whole wheat or even whole whole wheat, using Jim Lahey's no knead bread method, which has been posted all over creation. Lahey's method has a slow rise using little yeast. Bittman has a faster rise that gives you what he calls a whole wheat brick. Then he modified it. I haven't followed all that, having just tried the original Lahey no-knead recipe.
For some damn reason I've long hated regular whole wheat bread from the market. Baaaaad pillows. Turns out I like serious grain breads, not pabalum whole wheat. I've been mixing it up with Carol Field's italian bread book, but her recipes, region to region, usually involve a lot of kneading, including slapping wet breads (now that is fun). So, recently I've read Lahey's tricks work with whole grains too, so I'm going to fool with variations.
First place I learned to make bread - the Tassajara cookbook from way back when. They were early whole wheaters.
