The Viognier/Chardonnay glass is perfect for allowing white wines to express their freshness, spiciness, and mineral characters.
This glass is designed so the Viognier variety's low acidity is delivered in a way that sets off the alcohol and rich flavours of the wine. The shape highlights its velvety, supple texture, emphasizing the fruit and ensuring a long, balanced finish.This product is made of clear crystal glass.
Vinum is RIEDEL's basic varietal specific stemmed series. Designed in 1986 by 10th generation glassmaker Georg J. Riedel, Vinum was created to ensure every wine lover could afford varietal-specific glassware. Based on the handmade Sommeliers range, machine production means Vinum can be offered at a more accessible price.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.
