Wine Filtration Method and Apparatus

Many filtration systems overlook a major issue for oxygen-sensitive liquids like wine: oxidation during transfer and filtration. Even small amounts of oxygen can degrade quality. This apparatus provides a closed, inert-gas-pressurized filtration system that keeps wine fully protected from oxygen throughout the entire process. The setup includes a sealed holding vessel, an inline filtration unit, and a sealed receiving vessel. Inert gas is introduced into the holding vessel to gently push the wine through the filter without pumps, maintaining a continuous inert atmosphere. The wine reaches the receiving vessel with no exposure to ambient air, preserving its chemical integrity and ensuring accurate analysis. This system offers a simple, reliable, low-oxygen filtration solution for winemakers and producers of other oxidation-sensitive liquids.
