Definition - What does Still Wine mean?
Still wine is a type of table wine that is absent of any carbon dioxide which is what makes them still, not bubbly, sparkling or fizzy. Carbon dioxide (CO2) is a part of the fermentation process and is released when yeast and sugar mix, so all wines at one point in their development have bubbles present. Still wines, however, are treated to remove CO2, but sometimes, it can have few bubbles left over. These bubbles can be removed by using a decanter when pouring the wine to break up the remaining CO2.
WineFrog explains Still Wine
The majority of wines made today are still wines (not sparkling) and contain alcohol levels between 8-15%. Still wines are named after the region in which they are produced and lack aeration properties. When fermenting these wines, the CO2 is allowed to escape, and most of the bubbles are removed by natural departure.
Still wines may have some bubbles left over in the bottle but typically are not enough to influence the taste or character of the wine. These bubbles can be present or seen around the edge or bottom of the glass when poured but cannot be detected by the taster. They can also occur during shipping, and it’s best to open the bottle and let it settle before drinking. For a completely still pour, settling the bottle or using a decanter will remove any remaining CO2.
