Sparging of wine: don’t stress

Sparging of wine: don’t stress

High levels of dissolved oxygen in wine can lead to unwanted oxidation. Dissolved oxygen levels in wine are often reduced by sparging with an inert gas such as N2. However, the factors that influence the effectiveness of sparging and the effects it can have on the chemical composition of the wine were not well known prior to this study.

Winemaking factors such as gas flow rate, gas composition, wine temperature and bubble size were investigated on the efficiency of oxygen removal in wine.
