The brand that uses khorasan wheat in some versions? Yeah they're a little higher (14.7g/100g). We're stretching the definition of pasta now (it's certainly the highest protein grain you can find)
They do, but they have to use the standard numbers for durum (like everyone else, even growers - individual berries vary, of course). The only one I can find with these high numbers is the khorasan wheat versions[0].
