Primo grano meaning “first grain” in Italian, was an idea of pasta-maker Gianluigi Peduzzi, who wanted to bring back the flavors of authentic pasta made with 100% Abruzzo grown wheat like those that his grandfather, Gaetano Sergiacomo, made at his mill in the town of Penne at the turn of the last century. Spaghettoni meaning thick, bigger spaghetti. A regular spaghetti is 1.95 mm thick and the spaghettoni are 2.10 mm thick. The supple and meaty texture of the spaghettoni is for the true pasta lover. The PrimoGrano Spaghettoni are ideal to serve al dente and with simple sauces. The simpler the better, so you can taste the unique flavor of the Abruzzo grown wheat.
