Made from Glera grown in the Prosecco zone of the Veneto, this sparkling wine carries the Superiore designation that marks the region's higher tier, a step up from everyday Prosecco. La Marca's Luminore is a non-vintage bottling in the classic northeastern Italian mold, where Glera tends toward soft, orchard-fruit aromatics and a gentle, frothy bead rather than the fine, persistent mousse of Champagne.
