Question: what is the difference between bread flour and 00 flour?
Answer: Bread flour, says SFGate, is considered a high gluten flour, with a gluten content of up to 13 or 14 percent. Caputo 00 flour is a little lower, coming in at around 12 percent gluten. That's pretty much perfect and will give you a chewy crust without crossing the line and getting rubbery.
