The lower the temperature, the more slowly a wine develops. [4] On average, the rate of chemical reactions in wine double with each 18 °F (10 °C) increase in temperature. Wine expert Karen MacNeil recommends keeping wine intended for aging in a cool area with a constant temperature around 55 °F (13 °C). Wine can be stored at temperatures as ...
Tom Stevenson speculates that 52 °F (11 °C) may be the most ideal temperature for storage and aging, while Karen MacNeil recommends keeping wine intended for ageing in a cool area with a constant temperature around 55 °F (13 °C). Wine can be stored at temperatures as high as 69 °F (21 °C) without long-term negative effect. Professor ...
Wine generally matures differently and more slowly at a lower temperature than it does at a higher temperature. [2] When the temperature swings are significant, 14 degrees or more, it will cause the wine to breathe through the cork which significantly speeds up the aging process. Between 10–14 °C (50–57 °F), wines will age normally. [3]
The wine industry has long considered a constant temperature between 55 °F and 60 °F (13.0 °C and 15.5 °C) to be optimal for wine storage and aging. The air temperatures in Northern California result in a uniform underground temperature of about 58 °F (14.5 °C), optimal for wine caves.
Wine experts such as Tom Stevenson note that they may improve wine quality when used with moderation and care, or diminish it when used to excess. [3] Winemakers deliberately leave more tartrates and phenolics in wines designed for long aging in bottle so that they are able to develop the aromatic compounds that constitute bouquet. [ 2 ]
The system is based on both the hypothesis and observations that grapevines do not grow if the temperature is below 50 °F (10 °C). [2] Each day during the growing season are assigned growing degree-days according to the amount that the day's average temperature exceeds this threshold.

The physiological processes of a lot of grapevines begin when temperatures reach around 10 °C (50 °F). Below this temperature, the vines are usually in a period of dormancy. Drastically below this temperature, such as the freezing point of 0 °C (32 °F) the vines can be damaged by frost. When the average daily temperature is between 17 and ...
