In photography, mireds are used to indicate the color temperature shift provided by a filter or gel for a given film and light source. For instance, to use daylight film (5700 K) to take a photograph under a tungsten light source (3200 K) without introducing a color cast , one would need a corrective filter or gel providing a mired shift
In winemaking, ullage came to refer to any amount by which a barrel is unfilled, perhaps because some of the contents have been used. It is also applied to the unfilled air space at the top of a bottle of wine, which in this case is essential to allow for expansion of the contents as the temperature changes.

As a cork is ...

The biochemical process of fermentation itself creates a lot of residual heat which can take the must out of the ideal temperature range for the wine. Typically, white wine is fermented between 18–20 °C (64–68 °F) though a wine maker may choose to use a higher temperature to bring out some of the complexity of the wine.
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 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 ...
