The Coravin Aerator, enhances your wine experience by immediately mixing the right amount of air with the wine as you pour. This lets your glass of wine breathe without lengthy decanting, while ensuring the rest of the bottle remains perfectly preserved. Fits securely on the spout of all Coravin Wine Preservation Openers to aerate any amount of wine. Constructed from premium materials and featuring stainless steel accents, the Aerator uses 24 carefully placed and sized holes maximizing wines’ contact with air. Thin streams of wine are exposed quickly to air, producing similar results to decanting. This process yields smoother, more aromatic wines.
