What is kegged wine?
Kegged wine or draught wine is an environmentally friendly way to serve economically priced quality wines. Wine can be served out of a keg through beverage lines and out of a dispense faucet similar to draught beer systems.

Where can I find kegged wine options in my area?
Contact one of our Beverage Gas Experts and they will assist you in finding kegged wine options in your area. As your Beverage Gas supply partner Volunteer Beverage Carbonation is familiar with the ever increasing list of kegged wine options available.

Can my kegged wines be served out of my kegged beer cooler?
That depends on the type of wine (red or white), the keg cooler temperature and the type of gas and dispense pressure being applied to the wine keg. In most cases, a white wine can be dispensed from a kegged beer cooler when attention is paid to the parameters above. Red wines should be dispensed at a warmer temperature than kegged beer coolers will allow. Ideally a 50-58F cooler temperature is desired but often red wine kegs are stored at room temperature.

Is wine really carbonated?
Yes! There is a measurable amount of CO₂ dissolved in red and white wines. White wines contain more CO₂ than red wines. Obviously, wine contains much less dissolved CO₂ than carbonated soda or beer but the small amount of CO₂ dissolved in wine plays an equally important roll in wine flavor and shelf life. Maintaining the naturally occurring dissolved CO₂levels in wine can extend the flavor profile of kegged wine significantly.

What is the right kind of gas to use on my kegged wines?
The important role of any gas on top of wine in a keg is to be oxygen free and secondly to act as a propellant in dispensing the wine through the draught wine system. Oxygen-free nitrogen is the oldest used gas for this purpose. Nitrogen is inert and difficult to dissolve into wine. Nitrogen is the most widely used gas for kegged wine.

Why would I want to use nitrogen and CO₂ on my kegged wine?
Recently using nitrogen in conjunction with CO₂ on kegged wine has become the preferred method. The advantage of using a nitrogen/ CO₂ blend is to preserve the wine quality even further than using nitrogen alone. When a nitrogen/ CO₂ blend is applied, given the keg pressure and cooler temperature, kegged wine will maintain its natural CO₂ content and thus keeping the same flavor profile from full keg to empty keg.

What about argon gas?
Another less favorable gas option for kegged wine dispense is using argon gas. Argon gas is actually easier to dissolve into a liquid than nitrogen and may be less economical when compared to nitrogen. Nitrogen or more recently mixed-gas (blended Nitrogen & CO₂) have become preferred due to the fact that many beer retailers already have nitrogen on site.
