Line introduced in 2004


Broken stems are a thing of the past

In 2004, Maximilian Riedel caught the attention of the wine and tabletop industries with the introduction of his "O" Wine Tumbler series, an innovative collection of varietal specific stemless wine glasses. 

"The "O" glass has delighted many and outraged a few," said Maximilian. "People were quick to embrace a glass that offered all the enjoyment that RIEDEL is famous for yet was more casual, easy to use, wash and store and added a playful element to the wine and spirits experience."

This series has now become one of RIEDEL's best selling, and its success is easy to understand. Contemporary and chic, it is perfect for those who crave elegant yet uncomplicated designs for everyday use. It is a series that invites contact and intimacy while raising eyebrows. 

The "O" collection began for wine and has grown to include thirteen different glass designs, including six varietally-specific wine glass shapes, plus a glass for sparkling wine, water, saké, martini, and spirits. 

When asked why a glass for spirits, Maximilian Riedel explained, "I enjoy Port and spirits after dinner or as the evening winds down, and conversation deepens. I love the way you can roll the glass in your hand - it's almost contemplative."

"O" what will RIEDEL think of next?

The "O" Wine Tumbler series is produced by machine in lead-free crystal glass and sold in sets of two. All RIEDEL glasses are dishwasher safe.



The designs of the “O” stemless wine glass series are based on the benchmark shapes of RIEDEL's Vinum series. Design parameters such as the shape of the tumbler, size and diameter of the rim have been fine-tuned to enhance the world’s most important grape varietals. Because “O” wine glasses have no stem they are ideal for every day use, fit in every dishwasher, every small kitchen and make broken stems a thing of the past. The “O” Wine Glass collection is available as: Cabernet/Merlot, Pinot/Nebbiolo, Syrah/Shiraz, Chardonnay, Viognier/Chardonnay, and Riesling/Sauvignon Blanc. 


In 2006 the Riedel family introduced a casual way to enjoy Champagne and sparkling wine with the arrival of their “O” Champagne Glass. After all, there is something worth celebrating every day. Both Georg Riedel (10th generation) and Maximilian Riedel (11th generation) created designs for the glass, however Georg Riedel's design was ultimately selected for the collection. The hollow and ribbed narrow bottom gives way to a traditional Champagne flute bowl shape. As with all wine glasses, RIEDEL recommends filling it only a third full, so that the Champagne/sparkling wine aromas are evident. So pick up a Prosecco, serve a Californian sparkler, pop open a bottle of Champagne, or pour a Spanish cava into the RIEDEL "O" Champagne Glass.


Riedel has welcomed a cheery new addition to their innovative “O” collection, the aptly-named Happy “O”. An ode to spring, Happy "O" is available in four upbeat colours that lift the spirits —Dawn-Red, Spring-Green, Baby-Blue and Sunny-Yellow— and are perfect for water, juices and other soft drinks. While the sides of the glass are clear, the flat bottom of each is pastel-hued, providing a gentle wash of soft colour. Like all “O” glasses, the Happy “O” fits easily in the dishwasher, picnic basket, mini-bar or small kitchen. Without stems to knock into or over, the "O" is pet-proof and kid-friendly. Not to mention their fantastic price and clever packaging in a long, shallow egg crate-inspired box, making them an ideal gift.
