Sphera Wine Aerator
SPHERA is sculptured from solid brass with a scientifically calculated ribbed design, then traditionally silver-plated. As the wine runs down the ribbed surface, it opens out to the air, accelerating aeration. Contact between the silver-plating and the wine creates a chemical/physical reaction that encourages volatilization of sulphur dioxide, a substance which is sometimes added to wine as a preservative, or can form naturally during the ageing process. Use with a decanter or straight into the glass for maximum wine pleasure!
