Aging potential
There is a widespread misconception that wine always improves with age, or that wine improves with extended aging, or that aging potential is an indicator of good wine. Some authorities state that more wine is consumed too old than too young. Aging changes wine, but does not categorically improve it or worsen it. Fruitiness deteriorates rapidly, decreasing markedly after only 6 months in the bottle. Due to the cost of storage, it is not economical to age cheap wines, but many varieties of wine do not benefit from aging, regardless of the quality. Experts vary on precise numbers, but typically state that only 5–10% of wine improves after 1 year, and only 1% improves after 5–10 years.
