The Coravin Timeless Three+ wine preservation system was named one of Oprah's Favorite Things 2022. The state-of-the-art Three+ System uses a specially coated needle to pierce through the cork to allow you to pour wine without ever actually removing the cork. When finished pouring, the system uses argon gas to keep the wine fresh and sealed until the next pour. Care Instructions: After each use, rinse the spout with warm, clean water. Pay special attention to the clamps and the needle well. Ensure the clamps move up and down with ease. After rinse, press trigger to remove any water from inside the needle. Wipe with clean, damp cloth. Do not submerge system in water. Not dishwasher safe. Do not use detergent.
