Common Tasting Terms IDEAL WINE STORAGE CONSIDERATIONS
Temperature: The most important element about 
storage temperature is stability. If wine is kept in a stable 
environment between 40°F (7°C) and 65°F (21°C), it will 
remain sound. A small 1-2 degree temperature fluctuation 
within a stable environment is acceptable. Larger 
temperature fluctuations can affect the corks ability to 
seal, allowing the wine to “leak” from the bottle.
Humidity: The traditional view on humidity maintains 
that wines should be stored on their sides in 50% - 80% 
relative humidity to ensure cork moisture and proper fit in 
the bottle. Contemporary wisdom suggests that the cork 
surface is too small to be impacted by humidity. Further 
the cork is sealed with a metal or wax capsule making 
humidity penetration impossible. The concept of a humid 
storage environment was derived from the necessity of 
wineries to maintain moisture in their cellars to keep 
wooden barrel staves swollen, preventing wine 
evaporation and product loss. In fact, vineyards estimate 
as much as a 10% product loss per year due to 
evaporation while wine is aging in the wooden barrels. 
Humidity, however, was not intended for the modern 
home cellar where wine is stored in glass bottles with 
sealed corks.
Light: UV rays are not only harmful to people, they are 
damaging to wines - especially those in clear bottles. 
Since oxygen molecules in wine absorb UV rays, wine 
should never be stored in direct light for long periods of 
time.
Vibration: Provided that sediment is left undistributed 
and particles are not suspended, vibration in a storage 
environment is not an issue. Wines can become flat or 
tired when voids and vacuums are created inside the wine 
bottle. In order to create voids and vacuums within a 
liquid, aggressive motion or shaking of the wine bottle 
would have to occur. 
Terminology Description
Acidity A critical element of wine that is responsible 
for preserving the wines freshness. Excess 
acidity results in an overly tart and sour 
wine.
Balance A desired trait where tannin, fruit and acidity 
are in total harmony. Wines with good 
balance tend to age gracefully.
Body The weight and presence of wine in the 
mouth provided by the alcohol and tannin 
level. Full-bodied wines tend to have this 
strong concentration.
Bouquet The blending of a wine’s aroma within the 
bottle over a period of time, caused by 
volatile acidity.
Complex A subjective term often used in tasting. A 
wine is said to be complex if it offers a 
variety of flavors and scents that continue to 
evolve as it develops.
Flabby A wine that lacks structure, or is heavy to 
the taste, lacks acidity.
Full-Bodied Wine high in alcohol and extract, generally 
speaking, fills the mouth, powerful.
Lean Generally describes wines that are slim, 
lacking of generosity or thin.
Oaky A desirable flavor imparted to wine if done in 
moderation. Most wines are aged in oak 
barrels one to three years, thereby receiving 
this toasty oak characteristic. However, if a 
weak wine is left in contact too long with an 
oak barrel it will tend to be overpowered with 
an oaky taste.
Tannin Tannins are extracted from the grape skins 
and stems and are necessary for a well-
balanced red wine. Tannins are easily 
identified in wine tasting as the drying 
sensation over the gums. Tannins generally 
fade as a wine ages.
