I'm looking for a good, 100% whole wheat sourdough bread in Portland. The kind, if you're familiar with it, that Whole Foods does incredibly well. I've been to Standard Baking, Sofia's, Big Sky and One Fifty Ate, and still haven't found what I'm looking for. Despite the presence of a lot of good bakeries in town, I'm surprised by how much of the bread is white, and how hard it is to find whole grain/whole wheat here. Am I missing something?
