As producers of the most renowned crystal glassware Riedel were the first glass makers to design a functional wine glass that matched a specific shape with the character of a particular wine. Made in Austria and Germany Riedel use only the highest grade materials and expert techniques to produce a broad collection of the finest glassware. Perfect for young full-bodied (more than 12 percent alcohol) complex red wines that are high in tannin. This glass smoothes out the rough edges emphasizing the fruit allowing wines to achieve a balance that would normally take years of ageing to acquire. The generous size of this glass allows the bouquet to develop fully whilst the shape directs the flow of wine onto the zone of the tongue which perceives sweetness thus accentuating the fruit and de-emphasizing the bitter qualities of the tannin. Recommended for: Bordeaux (red) Cabernet Franc Cabernet Sauvignon Merlot Rioja Tempranillo. All Riedel glasses are dishwasher safe.
