Rocche dei Manzoni Barolo Rocche 2003 er en sammenblanding af Manzonis forskellige barolo-marker og en den eneste Barolo, som Manzoni har lavet fra årgang 2003. Den amerikanske vinguru Robert Parker er vild med den og giver 94/100 pts. Han skriver endvidere:

"It is a stunning, opulent wine, with layers of ripe dark fruit that flow from the glass with notable depth and luxuriousness. It possesses outstanding balance and is one of the highlights of the vintage. Rocche dei Manzoni remains less well known than it deserves to be, so this Barolo will likely fly under the radar. Discerning consumers, though, will want to give it careful consideration."
