Wine Dispensers aren't just a contraption to pour wine electronically or remotely, generally they also re-seal the wine bottle and ensure no oxygen enters the wine bottle so that the wine doesn't begin to oxidise and start to sour the taste. By using a wine dispenser, you can store an open bottle of wine for up to 4 weeks, which brings wine by the glass into the wine bar, restaurant , hotel and even your home.

How does a wine dispenser work?
A dispenser is not like a normal mechanical pouring system like a decanter, wine dispensers are fully automated and are controlled electronically. They ensure no oxygen enters the wine bottle to enable storage of an open bottle of wine for 3-4 weeks without oxidation.
What is oxidation?
Oxidation is a chemical process that effectively changes the taste of the wine, some call it souring. By allowing oxygen to enter the newly opened bottle, a few chemical reactions happen inside the bottle which raise the acidity level.
- After just 10-12 hours of being exposed to oxygen, the ethanol in the wine will react with oxygen to produce acetaldehyde and its the reason behind a wine tasting less fruity or flavoursome.
- Depending on the extent of exposure to oxygen, the next step in the reaction process is the break down of acetaldehyde with oxygen to form acetic acid. Acetic acid is a short chain volatile acid which is one of the primary causes of the souring of wines as it is one of the main chemicals found in vinegar.
This leaves you with a sour tasting, undrinkable wine which could be avoided with the use of a wine dispenser.
Preservation of wine:
A wine dispenser will control the way a cork is removed and some offer special caps which means you can open as many bottles as you like without the risk of oxidation.
Each system is different but generally when the cork is removed, a controlled amount of an inert gas such as carbon dioxide or argon will be introduced - therefore flushing the wine bottle of any oxygen as generally the molecular mass of these chemicals is higher than oxygen which means it will sit lower in the bottle.
When the wine is required for drinking, you can take the bottle out of the fridge, wine cooler and attach it to the wine dispenser. When a glass is being poured, the additional space created will be filled with the gas to ensure no oxygen enters the system. By doing this you can ensure that oxidation of the wine will not occur and the wine will be able to be kept like this for up to 3-4 weeks.
