I've baked whole grain breads in the past, and my attempts haven't failed, but I wouldn't say that they've succeeded either. The standards have been set so high by this bread from Great Harvest, that I felt like I may never be satisfied with anything else.
I was determined however, and after a long hiatus, I recently tried again. I made Peter Reinhert's sandwich loaf, from his whole grain bread book, and it turned out fantastic.
The bread is soft, and has great flavor, not the bitter, off-putting flavor often associated with whole grains, and it's perfect for sandwiches. This bread easily matches its counterpart from Great Harvest, and I'm debating baking a loaf every sunday. I really can't get enough of this bread, and though I would feel guilty if I put the recipe up here (i'm sure you can find it elsewhere) I urge you to try this for yourself, if not for the health benefits the taste.
