The Coravin Aerator, used with the Coravin Wine System, 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. Thin streams of wine are exposed quickly to air, producing similar results to decanting. This process yields smoother, more aromatic wines. Using the Coravin Aerator equals to 60-90 minutes of decanting.
