White wines are usually made from white wine grapes. Technically these wines are not white at all but rather yellow in color, white wines can be drunk on their own, or paired with light salads, white meats, or seafood dishes. Without the tannin found in reds, white wines are very approachable to people when first starting to drink wines. Not to say that whites should be regulated to the realm of the novice drinker, there are plenty of serious, complex white wines in the world that deserve your attention.
White wines can also be made using black grapes (the stuff red wines are made from), which is a bit counter-intuitive. Both white and black grapes, when pressed, yield a clear grape juice, what turns a wine red is by allowing the red grape skins to mix and soak with the clear grape juice. Without this soak, red wine grapes can be used to make white wines. Many Champagnes and sparkling wines use the juice of a black grape called "Pinot Noir" as a key component of the wine. The French even call Champagnes that are 100% made with Pinot Noir "Blanc de Noir" or "White from Black" referring to the color of the grape used. But in general, the vast majority of white wines are made using white grapes.
Unless a white wine has a high level of sugar and/or lots of acidity to act as a preservative, white wine does not age as well as their red brothers. To keep wines fresh and to extend the shelf-life, most winemakers use a chemical called sulfites to inhibit bacterial growth and preserve the wine. Because about 5 percent of asthmatics are extremely sensitive to sulfates many wineries label their wines with "contains sulfites" on the bottles. Organic wines sometimes forgo the addition of sulfites, and so they do not add the "contains sulfites" warning on the front of the label. The tannin in reds and the high level of acidity in very dry white wines help to preserve these types of wines, and so they do not need as many sulfites.
Styles
There are a few general styles with regard to white wines:
Fresh & Crisp
Crisp, light and without oak (aging in oak barrels will give a wine an "oaky" flavor, characterized by caramel, vanilla and smoke). Soave, Pinot Grigio, and Sauvignon Blanc all fall into this category.
Aromatic
Strongly scented wines, with medium body. The scent of the wine comes from the varietals used; German Rieslings, Australian Viognier and earthy Cote du Rhone wines are good examples of this style.
Rich
Classically defined by very oaky, rich, full-bodied Californian Chardonnays, or French Burgundies.
