We can't really deny that the majority of the population has virtually no idea about which wine glass goes with which wine. There are too many different and distinct shapes of wine glasses that it's daunting to even begin to muster the interest in learning the specifics. Because of this, many have resorted to using tumblers to drink any kind of wine. To make up for the crudeness of wine drinking in tumblers, they pick ones that are made to look elegant one way or another.
Understanding the basics of the relationship between wine and wine glasses isn't really very difficult. Once the anatomy of the wine glass is understood, it becomes fairly easy to determine which one to use later on. The rather lavish look of wine glasses because of its long, thin stem makes it seem that it's more focused on form rather than function. Initial assumptions would dictate that the stem where the hand should grip the glass to make it look more classy while drinking. However, the stem serves an important purpose. Indeed, the hand should go here when holding the wine glass but not for mere aesthetic reasons. Holding the wine glass on the stem prevents the hands from touching the bowl that would otherwise compromise the wine content. Almost all wine has a recommended ideal temperature for drinking and holding it around the bowl would make the temperature of the wine adjust to that of the hand's. Some wine glasses will have thicker bowls to mitigate this transfer of heat. But these thick glasses are discouraged by wine connoisseurs because it's too bulky and heavy that it makes wine drinking slightly inconvenient. Purchase wine glasses with good stem length such as wine glasses on Amazon and other reputable sources.
The bowl of the wine glass is arguably the most important part of the three. The most noticeable difference between bowls is that some are thin while others are wide. These thin wine glasses are called narrow wine glasses and are made to contain certain types of wine. The most popular wine that makes use of narrow glasses is champagne. Champagne should have as small as possible surface area in contact with air. This is because less oxidation in champagne means the flavor is much better. The drink will retain most of its fizz even if left untouched for a couple of minutes if the glass is narrow. Another good thing about champagne in narrow glasses is that the bubbles from the champagne look beautiful when creeping up the side of the tall, narrow glass. Wide bowls on the other hand serve the exact opposite purpose. It encourages oxidation in wine where flavor is improved if done so. The large surface area of the wine exposed to air ensures that a lot of oxidation happens immediately after wine is poured. While this basic information are arguably sufficient to get by, it is highly advised to learn more and fit just right in when in a posh social gathering.
