Thanks to its exchangeable valves, the Uno Vino can oxygenate various types of wines in an appropriate way while the wine is being poured into the glass: the red valve, which has nine openings, is perfect for red wines, while white wines are oxygenated using the green valve, which has three openings. The anthracite valve, which has no openings, serves as a spout for rosé wine. The aerator as well as the valves are kept in a convenient stand. Users simply need to attach the appropriate valve before serving the wine.
