Since this answer was first posted in chemistry, you may want to follow the nearby link to an excellent paper on what happens when a wine oxidizes. Wine lovers may read on. Unless we're talking about Sherry, Madeira, or perhaps Marsalla, the only role oxidation plays in wine making is that of the villain. Oxidation (which is not the same thing as oxygenation, which is desirable in the early stages of beer brewing) is almost always bad. Notable exceptions are in the making of some Sherry and Madeira, the latter being cooked a bit to cause oxidation of the wine. Oxidation imparts a taste that is difficult to describe but is, curiously, desirable in some sweeter Sherry wines and in Madeira. Not too surprisingly, oxidation in other wines is also called, somewhat euphemistically, "maderization." Once you've tasted Sherry and Madeira, you will be able to recognize the notes and tastes of undesirable oxidation in other wines (and even some liqueurs). Another sign is an unattractive darkening of the wine. Oxidation is not as offensive in sweet wines, but if you have a dry wine that has oxidized, well, then the only recourse is to invert the open bottle over the kitchen sink.
What else can I help you with?
What happens to rubidium when it is exposed to air?
Rubidium reacts quickly with oxygen in the air, forming a yellow oxide coating on its surface. This oxide layer can catch fire spontaneously in air, so rubidium is usually stored under oil to prevent contact with oxygen.
If wine that's stored in barrels after fermentation is exposed to too much air this could turn the wine into?
If wine stored in barrels is exposed to too much air, it can turn into vinegar due to the oxidation process that occurs. Oxidation can spoil the wine by producing acetic acid, the main component in vinegar. This can alter the flavor profile and aroma of the wine, rendering it undrinkable.
Which metal become brown in colour when it is oxidised?
Iron is a metal that turns brown in color when it oxidizes. This brown color is known as rust, which forms when iron reacts with oxygen and moisture in the air.
What substance is formed when alcohol is oxidised by the air?
When alcohol is oxidized by the air, it forms acetaldehyde, which is a toxic compound. This oxidation process usually happens when alcohol is exposed to air for an extended period of time, resulting in a change in flavor and quality of the alcohol.
Which new gas is formed when carbon monoxide is oxidised?
Carbon dioxide is formed when carbon monoxide is oxidized. Carbon monoxide reacts with oxygen in the air in the presence of a catalyst to produce carbon dioxide.
What does wine go sour in air?
because it gets oxidised when it gets contact with air.
Is oxidised wine injurious to health?
No oxidised wine will not harm you. Some cultures even enjoy oxidised wines because they take on a sherry like flavor. When a wine oxidises it just means that unnecessary air has entered into the bottle. This can happen many ways; cork has come slightly lose and air has entered the bottle or, the bottles haven't been properly stored.
What happens to rubidium when it is exposed to air?
Rubidium reacts quickly with oxygen in the air, forming a yellow oxide coating on its surface. This oxide layer can catch fire spontaneously in air, so rubidium is usually stored under oil to prevent contact with oxygen.

If wine stored in barrels is exposed to too much air, it can turn into vinegar due to the oxidation process that occurs. Oxidation can spoil the wine by producing acetic acid, the main component in vinegar. This can alter the flavor profile and aroma of the wine, rendering it undrinkable.
What happens when substances burn in air?
Oxygen is used up.
What happens when there is less oxygen in air?
Everyone will suffocate and die..
Steel wool rusts if you use it and leave it on the edge of the sink what must steel wool be made of in order to see this reaction?
Any metal which can get oxidised in the presence of oxygen from the air and water.
What use does a wine breather provide?
As a wine is exposed to oxygen, it releases additional aromas and flavors. This can enhance a fine wine or expose flaws in a cheaper version. When a wine bottle is uncorked, there is only a small amount of surface area exposed to the air. Using a wine breather or wine aerator, the whole amount of the wine will be exposed to air and therefore reach a more mature flavor.
Which metal become brown in colour when it is oxidised?
Iron is a metal that turns brown in color when it oxidizes. This brown color is known as rust, which forms when iron reacts with oxygen and moisture in the air.
What happens to the partial pressure of oxygen in a sample of air when the temperature increases?
When the temperature of a sample of air increases, the partial pressure of oxygen also increases.
What is the chemical name of the pale grey coating on the sodium?
The pale grey coating on sodium is sodium oxide (Na2O) or sodium hydroxide (NaOH) that forms when sodium reacts with oxygen or moisture in the air.
How does the process of oxidizing wine affect its flavor and quality?
When wine oxidizes, it reacts with oxygen in the air, which can change its flavor and quality. This process can lead to the wine tasting more flat, dull, or vinegary, and can diminish its overall quality.
