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.

All About White Wine
Light White Wines
Refreshingly light and crisp, sometimes a hint of citrus, these wines pair best with appetizers, finger foods, poultry, fish and light pasta dishes.
Fruit and Sweet White Wines (off dry)
Lots of fruity flavours to pair with spicy dishes.
Full Bodied and Flavourful White Wines
A little less fruity and more hints of nuts, spice and even vanilla. These wines pair best with fish, seafood, and cream sauces.
Remember that wines from different countries will taste slightly different, even if they are the same variety of grapes. Try a few different ones and attend some tastings to really find your preferences.
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!
