Founded in 1756, Austria's Riedel Crystal is the world's premier manufacturer of wine glasses and has always catered to the fine wine connoisseur. However, these wine tumblers are part of the company's first attempt at producing a lower priced wine glass for casual entertaining. Like Riedel's prestigious Vinum series of glasses, these tumblers are specifically designed for a particular grape variety and still maintain their ability to enhance the flavors and aromas of the wines they were intended for. The only difference is that the tumblers are missing their stems, making them slightly less delicate to handle, more modern in appearance, and easier to fit in smaller cabinets, mini bars, picnic baskets, and the dishwasher. The O series of glasses are made of machine-made of non-leaded glass. The shape of this glass is specifically recommended for full-bodied red wines, such as Pinot or Nebbiolo. Each glass holds 23-7/8 ounces of wine, stands 4-1/2 inches tall, and is completely dishwasher-safe
