Asiago Sour Dough

This is a loaf of country sourdough bread with asiago cheese I made yesterday. I used a cast iron dutch oven to bake the bread in. As a result I got better oven spring and a much better crust than just tossing it into the oven on the baking stone. The crumb is pretty open, although not quite where I want it yet, but I think my yeast weren't too active, so most of the openness in the crumb is simply from evaporation.
