Riedel (Austria) revolutionized the world of glassware by introducing a radical concept: “The content commands the shape.” Unlike Baccarat or Waterford, which focus on decoration, Riedel focuses entirely on physics and oenology (the study of wine).

Claus J. Riedel was the first in history to design glass shapes specifically to enhance the character of different grape varieties.

Riedel believes that the shape of the glass (the bowl size, rim diameter, and rim finish) directs the wine to specific zones of the tongue (sweet, sour, bitter) and controls the nose (aroma), drastically altering the tasting experience.

• Thin Rims: Riedel glasses often feature cut rims (rather than rolled rims), allowing the wine to flow smoothly onto the palate without obstruction.
• Grape Varietal Specific: They produce specific glasses for Cabernet, Pinot Noir, Chardonnay, Riesling, etc.

• Sommeliers (1973): The world's first gourmet glass collection. Mouth-blown, unadorned, and designed with the help of the Italian Sommelier Association.
• Vinum (1986): The first machine-made glass in history to be based on the characteristics of grape varietals. It made professional wine enjoyment accessible to a wider audience.
• O Series: A controversial but popular line of “stemless” wine tumblers, designed for casual elegance and easy storage.
