If you are worrying about which Caputo 00 you have, I think there is no cause for concern. Originally, Orlando Foods, the importer of the Caputo flours, was using 10 1-kilo bags for samples. However, because they were also selling the Extra in 10/1-kilo bundles, this led to confusion. Now the samples of the pizzeria 00 flour, such as PizzaBrewer received, come in a 10 kilo bag. This explanation was given to me by my contact at Orlando.
