If you know nothing about wine, here's some wiki facts for you about how wine is made.
Wine is an alcoholic beverage made from fermented grapes or other fruits. The natural chemical balance of grapes lets them ferment without the addition of sugars, acids, enzymes, water, or other nutrients. Yeast consumes the sugars in the grapes and converts them into alcohol and carbon dioxide. Different varieties of grapes and strains of yeasts produce different styles of wine. The well-known variations result from the very complex interactions between the biochemical development of the fruit, reactions involved in fermentation, terroir and subsequent appellation, along with human intervention in the overall process.

Wine Tasting:
Wine tasting is the sensory examination and evaluation of wine. The sweetness of wine is determined by the amount of residual sugar in the wine after fermentation, relative to the acidity present in the wine. Some wine labels suggest opening the bottle and letting the wine "breathe" for a couple of hours before serving, while others recommend drinking it immediately. Remember that there are specific glasses meant for red and white wine. Your local store will have them clearly labeled!
Tip: Host a fun wine tasting event of your own by inviting guests to bring their favourite wine from around the world. Buy tasting glasses and let all the guests rate how they like each one. Serve with light appetizers and cheese for the best pairing!
