Carbon Dioxide Injection
Definition - What does Carbon Dioxide Injection mean?
Sparkling wines can be made using different processes, depending on the type of sparkling wine being produced. Regardless of the method used, sufficient amounts of carbon dioxide is instrumental in ensuring the bubbly nature of the sparkling wine. The easiest and cheapest technique to introduce carbon dioxide into the wine is by directly adding the gas into it. This process is known as a carbon dioxide injection and is a lesser quality method of introducing CO2 into the wine.
WineFrog explains Carbon Dioxide Injection
The act of injecting carbon dioxide is performed using a carbonator that directly introduces carbon dioxide gas into the liquid. Apart from sparkling wine, this process is often used during the production of carbonated sodas.
A large portion of determining the quality of a good sparkling wine revolves around the size of the bubbles. Traditional fermentation processes produce quality wines with small, elegant, desirable bubbles that last long in the glass when poured while CO2 injection produces wine with large, awkward bubbles that dissolved quickly - the mark of a low quality sparkling wine.
This is a definite sign of low quality sparkling
