Zalto Universal Glasses: Taste the difference in every sip. These glasses work wonders with both red and white wines. Each glass is mouth-blown from a single piece of pristine glass, ensuring elegance from lip to stem. Wine enthusiasts laud it as the perfect Riesling glass, but it truly shines with Chardonnay, Gruner Veltliner, Chianti, and roses. Skilled glass-blowers craft each glass, using time-honored traditions and the finest materials.
