I have to put up a quick plug for a new website by flour maker Stone-Buhr. Full disclosure: The company just paid me to write some copy about it on their packaging. But it's very cool and exactly the type of thing that I'm interested in!
FindTheFarmer.com lets you type in the lot number on your package of flour and see where the wheat that went into it came from. Most wheat that we consume is an anonymous commodity hailing from who-knows-where, but Stone-Buhr has cultivated relationships with bona-fide independent family farms in the Pacific Northwest and is, I believe, the first company to offer identity-preserved flour, as it's called. Not only that, but these farms are using sustainable methods certified by the Food Alliance. Interestingly, the flour is not organic, but it's still considered sustainable. That's a post for another day...
