I have checked out two brands of sour dough bread still available. San Louis Sour Dough Bread, I found the sour dough taste to be slightly stronger then Colombo. I actually prefer this San Louis Sour dough ov3er Colombo, so this has soften the blow of losing Colombo Sour Dough Bread. The one bread that came in a close second was Boudini Sour Dough Bread.
