Just a heads up for Central Milling flour fans. A while back I asked Costco if they could start carrying the Organic Artisan Bakers Craft Plus Malted flour from Central Milling. I just heard back and they'll be stocking it in 25# bags starting mid-July (2013) once they've depleted their stock of the CM Beehive Organic flour it's replacing.
Organic Bakers Craft is a blend of hard red wheat, malted with 11.5% protein. It's 1% higher protein than the Beehive so should produce dough with a little more strength, which is what I was looking for. As a reference, King Arthur all-purpose flour has 11.7% protein.
If you're in the San Francisco Bay area you should be able to find it in Redwood City, Mountain View, Almaden, Santa Clara, San Jose, Fremont, Santa Cruz and some other locations I didn't write down. Outside the Bay Area you'll have to check with Costco for locations. The item number is 475605.
As a bonus I believe this is the same flour the Tartine Bakery uses for their famous sourdough bread but don't quote me since I'm not 100% sure.
