Wonderful bread can be found in some very unexpected places. In the rolling countryside of western Wisconsin, a bakery is tucked away in a location that receives a lot of double takes. The Castlerock Sourdough bakery is many things – it’s well stocked, filled with flavors, and it’s open 24 hours a day. It also just happens to be the smallest bakery in Wisconsin. It’s a tiny little place you have to see to believe – here’s what you need to know about Castlerock Sourdough.

Castlerock Sourdough is located in Buffalo County, in far western Wisconsin. If you had a good arm, you could throw a loaf of sourdough and just about hit the Mississippi River.

The bakery’s storefront is a “bakery hut,” a tiny yellow building that’s loaded up with baked goods. It’s all made using high-quality, locally milled flour, like Bay State Mill.
