Superleggero Hermitage / Syrah, 1-Pack from Riedel. Superleggero from Riedel is completely handmade and mouth blown, made in the factory in Austria. Superleggero is made of extremely thin crystal and is often classified as pioneering when it comes to grape-specific, mouth-blown wine glasses. The design is eye-catching and beautiful with its taller and thinner shape. Superleggero consists of ten wine glasses in crystal and all can be machine washed.
