A Wine glass is a type of glass stemware that is used to drink and taste wine
from. Selection of a particular wine glass for a wine style is important, as the
glass shape can influence its perception.
Wine glasses made of fused or cut glass will often interfere with the flavor
of the wine, as well as creating a rough, thick lip, from which it is not as
pleasurable to drink. Blown glass results in a better vessel, with a thinner lip, and
is usually acceptable for casual wine drinkers. High quality wine glasses are made
of crystal, which is porous and helps to aerate the wine. Crystal glasses also produce
a better ringing sound when toasting. Wine glasses are generally not coloured or
frosted as this would impede the appreciation of its colour.
The shape of the glass is also very important, as it concentrates the aroma
(or bouquet) to emphasise the varietal's characteristic. The shape of the glass
also directs the wine itself into the best area of the mouth from the varietal. In
general the opening of the glass is not wider than the widest part of the bowl.
The stem of a glass is an important feature as it provides a way to hold the glass
without warming the wine from body heat. It also prevents fingerprints from smearing
the glass, and makes the glass easier to swirl. Except for the wine connoisseur, wine
glasses can be divided into three types: red wine glasses, white wine glasses and
Red wine glasses
Glasses for red wine are characterized by their rounder, wider bowl, which gives the
wine a chance to breathe. Since most reds are meant to be consumed at room
temperature, the wider bowl also allows the wine to cool more quickly after hand
contact has warmed it. Red wine glasses can have particular styles of their own, such
Bordeaux glass: Tall with a wide bowl, and is designed for full bodied red wines
like Cabernet and Merlot as it directs wine to the back of the mouth.
Burgundy glass: Larger than the Bordeaux glass, it has a larger bowl to accumulate
aromas of more delicate red wines such as Pinot Noir. This style of glass directs
wine to the tip of the tongue.
White wine glasses
White wine glasses are generally narrower, although not as narrow as champagne
flutes, with somewhat straight or tulip-shaped sides. The narrowness of the white
wine glass allows the chilled wine to retain its temperature for two reasons;
The reduced surface area of the glass (in comparison to red wine glasses) means less
air circulating around the glass and warming the wine.
The smaller bowl of the glass means less contact between the hand and the glass, and
so body heat does not transfer as easily to the wine.
Champagne flutes are characterised by a long stem with a tall, narrow bowl on
top. The shape is designed to keep sparkling wine desirable during its
consumption. The glass is designed to be held by the stem to help prevent the heat
from the hand from warming the champagne. The bowl itself is designed in a manner
to help retain the signature carbonation in the beverage. This is achieved by reducing
the surface area at the opening of the bowl.
Champagne flutes are often used at formal engagements, such as award ceremonies
