At one time, Tony Gemignani used Stagioni flour for some of his pizzas, and so noted that on his menu, but that flour is no longer mentioned in his menu. According to the current menu, for the Neapolitan style pizza, he is using either Caputo or San Felice. For the coal-fired pizzas, he is using Caputo and Giusto's. Maybe there is a good reason for the switch other than price or availability.
