Serves as a cork, portioner and wine decanter. Once the wine bottle is uncorked, IL Decantino inserts securely into the bottle. Remove the small cork from the pouring spout, then simply tip the wine bottle forward, and the glass bulb fills to portion and aerate the wine at the same time. When the bulb is filled, tip the unit to empty the decanter and fill the glass. The wine served is perfectly portioned and ready to drink. No need to wait for the wine to “breathe” – the bouquet and flavors are immediately apparent. Replace the small cork in IL Decantino and enjoy!
