Red Wine Glasses

• The bowl of glasses for red wines is wider to accommodate more air, which helps to release the bigger aromas and flavors of reds. The opening is also wider to allow for the nose to more easily enter the bowl. Big, more full-bodied reds, such as Cabernet Sauvignon and Merlot demand a broad bowl and narrower opening that directs the wine to the back of the mouth, such as in the classic Burgundy glass. Softer reds, such as Pinot Noir, require a big bowl and wider opening to allow for better air infiltration. The Bordeaux glass is a good example.
  
  

White Wine Glasses

• Because they are chilled, white wines require a more narrow bowl to keep them cool longer. the opening should also be narrow to preserve the lighter scents of whites from oxidation. Stronger whites like Sauvignon Blanc and Chardonnay need a bowl that is a bit on the larger side with an opening that narrows slightly. Finer whites such as Riesling, Pinot Gris and Gewurztaminer do best with a narrow bowl and opening.
  
  

Champagne Glasses

• While the old-style champagne saucer or coupe is traditional, a flute is the preferred glass for serving champagne and other sparkling wines. The tall sides of the flute reduces the amount of CO2 released, keeping the champagne from going flat.
  
  

Sherry and Port Glasses

• Because Sherry and Port are bold, aromatic wines for light sipping, smaller servings are typical and glasses should accommodate. The bowl and opening should be relatively narrow to concentrate the aromas.
  
  

ISO Glass Standards

• The International Standards Organization has standardized series of glasses for wine. They are all stemmed with elongated tapered bowls. They hold 120 ml. for sherries and ports, and 210, 300, and 410 ml. respectively.
