Flour

I just purchased 25 Kilograms flour. The miller said that it did not contain any chemical additions, so I am expecting a lot of this flour. I cannot use it yet, because I need to use the rest of my other flour first. Also I did get 15 Kilograms (yes, 15!) of rye flour. I hope I can use it all before the expire date which is May 18. Seems like I will need to make a lot of rye breads :-)
