The Syrah/Shiraz glass is perfect for medium-bodied red wines. Its unique flat-bottomed design accentuates the bold fruit aromas, allowing the bouquet to develop in detail. It balances spice, earth and toasty characters with the smooth tannins typical of medium-skinned red wine grapes.RIEDEL Winewings is a brutally functional glass collection, taking wine's aromas and flavors on a flight. Made up of several new shapes, these flat-bottomed glasses are reminiscent of the wing of an aircraft. This means the wine has a greater surface area in the glass, which increases the levels of evaporation and enables a greater intensity of aroma.This item is premium machine-made. "PREMIUM" defines the advantage of a machine blown RIEDEL glass vs. a hand-made glass. The difference lies within the precision. This item is dishwasher safe. This pack contains a single piece.
