This is a recipe from an old cookbook. I only have a few pages left so I can't say what the cookbook was called or where it came from. I found the pages glued to cardstock in the pages of a binder which belonged to my grandmother. I made this starter for the first time a year ago and have kept it going. It makes a wonderful loaf of bread, tastes like REAL sourdough to me. It has beer in it ( the brand with rocky mountain water in it) and I had never seen this in a starter before. The bread made takes a nice flavor from the beer which I have not experienced in other starters. I hope everyone likes it as much as I do ! I will also be posting the bread recipe. ENJOY!!!!!!
