Sourdough - First Attempt

It has been quite some time since I made a sourdough starter and the first time in this new environment. So I started with some beer trub that was full of leftover beer yeast, 2 tablespoons added to 3 tablespoons flour and 4 tablespoons water. After 4 days of "feeding" my little starter friend, I had a thick starter that doubled in size each feeding. It looked like this....

I cut the starter in half - feeding the remaining half and using the other half for bread. 

I added the cup of starter and 3 cups warm water then mixed the result.....

After adding the water I stirred in 5 cups of regular white flour...

I let the dough rest all day and before bed, I uncovered mixed and formed into two loaves. I was slightly bothered as the dough had become almost a liquid but thought I would give it a chance. Turns out by using regular white flour it took in to much moisture becoming to wet and held no shape I baked it anyway and while not pretty by any means it was tasty!

I made another batch the next day changing the white flour to bread flour and cutting the water down by a half cup. Turns out the next batch was to dry. So the next batch I make I will be doing 5 cups bread flour, 2 cups water, and 1 cup starter. We shall see how the next batch works!
