The world’s red wines, which are typically aged for between eight and nine months, are often given a much lower temperature than other wine varieties.
They are often bottled at the lower end of the range, making them a good choice for a dinner party or a holiday.
The temperature is a vital element of the experience and the red wine industry is hoping to find a way to keep the wine at a comfortable level by limiting the temperature in the bottle.
But it has a major problem.
Red wine can vary widely in temperature during the course of its aging process.
Some wines are more vulnerable to oxidation than others.
In some cases, they will even change colour from red to a pale yellowish-green in the middle of the bottle while others will change colour to an orange-brown in the bottling process.
In many cases, the colour change is permanent.
“There’s no way to control the colour of the wine without knowing the temperature,” says wine expert Mark Evans, author of The Wine Code.
“A wine can be very opaque, and then it’s red and then suddenly it’s dark and suddenly it turns to amber.
If the temperature is too low, the wine will taste bitter.”
To get around this, the industry is looking at the most effective ways to control temperature.
The most recent innovation is called temperature management, which involves controlling the temperature of the wines before bottling.
In theory, the idea is that by allowing the wine to warm up and cool down, the flavours will change, giving a better experience.
But in practice, there are several caveats.
It is possible for the wine in the glass to become cloudy, and the wine’s taste can become harsh.
If you’re not sure how to control this, it can lead to the wine becoming overly sweet.
“When the wine is being aged in the same room, it’s a different experience,” says Evans.
“In terms of a chilled glass, you can taste it differently.
That’s the key to having the right temperature.”
There are a number of ways to cool a wine.
Some older wines will come with a small fan to help circulate the air.
Others, such as the red wines of Chile, will come equipped with a fan that can be controlled from the glass.
But for a bottle of the Cabernet Sauvignon from the south-west, there is no fan and it’s all about controlling the bottle temperature.
According to the Wine and Spirit Alliance, a trade body for the industry, the best way to reduce temperature in wine is to allow it to cool down to the bottle’s internal temperature, between 50 and 60 degrees Celsius.
This is achieved by letting the wine cool down and then cooling it back up, which gives the wine a longer shelf life.
“The bottle should never be above 40 degrees Celsius, it should never go above 90 degrees Celsius,” says Michael Tulloch, a senior wine industry consultant at the Wine Alliance.
“It should never touch the bottom of the glass, it needs to stay below 40 degrees.”
He adds that the glass should always be open, to allow air to circulate through the wine.
This will help keep the flavours from becoming bitter.
But what about the red, sparkling wine?
The temperature of red wine depends on how long it’s been stored in the barrel.
“Some of them are actually very delicate and will stay red and sparkling for decades, whereas others will lose colour in the first few weeks or months and become pale yellow in the end,” says Tullos.
“That’s why we’re looking at temperature management.”
If a wine is not being kept in the cellar, the bottles can be kept in a cool, dry place and the temperature controlled through the bottle, according to the industry.
If it’s stored in a warm, dry area, however, then the wine could develop flavours that are not as good as they would be at a cooler temperature.
That can cause an imbalance between the taste of the alcohol and the taste in the wine, and it can affect how the wine tastes.
“For wine that has been stored for longer, it is more likely to become more bitter and sweeter, because the alcohol will start to lose its flavour,” says David Taylor, a wine industry expert at the Australian Institute of Wine.
“If the wine has been bottled for a longer period, it will become more opaque.”
This is why, in order to maintain a consistent taste in wine, the bottle should always stay open.
To make sure that the bottle remains open and free of residual flavours, the glass must be sealed with wax or other barrier material before it is opened, according the Wine Code, and must be kept at a temperature between 40 and 60°C.
A number of wine producers, including British wines, have developed their own packaging to improve the taste and colour of their wines.
They also use carbon dioxide to prevent spoilage of the colour from the wine and the packaging is made of
