Riedel O Wine Tumbler Set of 8 (Cabernet/Merlot, #0414/0) – premium fine crystal glasses designed to enhance the aroma and flavor of Bordeaux-style red wines. Each tumbler holds 600ml (21⅛ oz), with a modern stemless design, 121mm height, and 95mm widest diameter—perfect for Cabernet Sauvignon, Merlot, and similar varietals.

A practical and generously proportioned stemless Cabernet/Merlot glass that combines Riedel's varietal-specific bowl design with the convenience of the O Wine Tumbler format. The large 630 ccm bowl is particularly well suited to structured Bordeaux varieties, while the stemless construction makes this eight-piece set ideal for everyday entertaining and larger gatherings.

O (2004) is the first varietal specific wine tumbler in history. O is an innovative take on the casual wine glass for total wine enjoyment. O is based on the benchmark shapes of RIEDEL VINUM to enhance the world's most important grape varietals. The tumbler, used for centuries as an all-round drinking vessel, is now turned into a sophisticated wine accessory. It fits into every dishwasher. Broken stems are a thing of the past. O is executed in non-lead crystal, machine blown in Bavaria, Germany.

Features
Signature Shape: The Cabernet/Merlot O Wine Tumbler uses a large, gently narrowing egg-shaped bowl designed to give full-bodied red wines room to develop their bouquet.
Cabernet / Merlot Focus: Specifically designed for powerful, tannic reds including Cabernet Sauvignon, Merlot, Cabernet Franc, Carménère, Petit Verdot and Bordeaux blends. The generous bowl helps emphasise fruit while making firm tannins feel more integrated.
Aromatic Performance: The spacious 630 ccm bowl provides ample surface area for complex aromas to unfold, helping reveal dark fruit, spice and structural nuances while supporting a balanced palate impression.
Stemless Design: The O Wine Tumbler was introduced in 2004 by Maximilian J. Riedel as the first varietal-specific stemless wine tumbler. Its bowl is based on the benchmark varietal-specific shapes of the Riedel Vinum collection, retaining their functional approach in a more casual format.
Everyday Practicality: The absence of a stem makes the glass easier to store and less vulnerable to broken stems, while its machine-made crystal construction provides consistent quality and durability.
