Vino Dose Aerator and Wine Dispenser provides the perfect pour. The double task of aerating and measuring the wine is done easily with this acrylic Vino Dose Aerator and Wine Dispenser. It mounts onto a wine bottle. The bottle is tilted to fill, or partially fill, the bowl. A natural fill stops automatically at the 4 oz. mark. But there are graduated fill lines ranging from ½ oz to 4 oz. Bottom screws off for easy cleaning. 5-1/4” wide (on the bottle), 3-3/4” high.
