*Patented Design: Our patented aerating wine glasses are handmade of durable, high-quality tempered glass and features a wine aerator built into the glass. The glasses instantly aerate 7 oz of wine on each pour. *Instant Wine Enhancement: The aerator allows air to be infused into your wine, which enhances its flavor, aroma, and taste. It also helps to soften tannins and reduces bitterness. *Wine Aerator: Simply pour through the glass and the wine will aerate as it showers through the aerator. It aerates your wine as you pour, so you can enjoy it at its best. Use a block of ice in the aerator to cool white wine or spirits as they aerate. *Unique Gift: Our stemless aerating wine glass is a unique gift for any wine lover. It is perfect for weddings, parties, and other special occasions. *Dishwasher Safe
