The exceptional handmade Riesling and Zinfandel glass of the eye-catching glass collection Fatto A Mano stands out due to a Black stem. The shape of the glass best supports the characteristic bouquet of fruity red wines or floral white wines – aroma and taste are dominated by fermented grape juice and the flavor of yeast. Combining the sophistication of hand-made glass in the style of the ancient Venetian tradition with the very latest glass making technology. All RIEDEL glasses are dishwasher safe.
