Acidity: A substance in grape juice that makes you pucker when you sip, like when eating a lemon. Acidity comes from the skins.
Aging: Aging mellows tannins (see 'Tannins'). Although 90 percent to 95 percent of all wine should be consumed within one year after it's bottled, the remaining big boys -- Bordeaux and Burgundy, Spanish and Italian reds, and some California Cabernet Sauvignons -- need to be left alone in the bottle to chill out.
Balance: When everything in a wine comes together perfectly. The acids aren't too strong, and the astringent tannins don't kick you in the teeth.
Big: Mostly a word for red wines, meaning lots of beefy flavor and alcohol. Big wines normally need to age before most people would want to come near them.
Body: Wine is normally described as light-, medium- or heavy-bodied, indicating how heavy the wine feels in your mouth. Kevin Zraly, famed wine educator, invented a way to teach people about 'body.' Think of it as different grades of milk. Light-bodied wines imitate skim milk in the mouth; medium-bodied wines are like whole milk; and full-bodied equals heavy cream.
Complex: Complex wine has a lot of personality, and its flavor holds on through the entire sip -- from the first taste of fruit to a long-lasting finish (see 'Finish').
Crisp: Sharp acidity in a wine. Normally a compliment for whites.
Dry: Not sweet. Dry wines have most of the sugar fermented out of them so there's no sense of sweetness on the tongue.
Finish: Refers to the flavor lingering in your mouth after you take a sip. 'A long finish' means the flavor lasts a few seconds or more.
Nose: The aroma of a wine. To really 'get' the nose, stick your own nose all the way into the glass and breathe deeply.
Oaky: The wood taste imparted by the oak barrels or oak chips used during fermentation or aging.
Palate: The flat part of the tongue. Sometimes broken into 'front,' 'mid' and 'back.'
Structure: The architecture of a wine: the smell, the feel in your mouth, the tannins, acidity and fruit. 'Good structure' is a fabulous compliment for a wine.
Tannins: The drying substances found in the seeds and skins of the grape, mostly in red wines. You can feel tannins as they suck the moisture from your mouth, just like strong-brewed tea. Tannins also enable wine to age.
Tight: Refers to a red wine's reluctance to be friendly or fruity when you first pour it in the glass. A young wine high in tannins might be 'tight' before it gets mixed with oxygen -- achieved by swirling. Oxygen helps release its flavors and relax its aroma and flavor.
