Oenophilia Porto Decanter Set These hand-blown serving glasses date back to 17th century Europe, where they were known as Schnapps Pfeiffen The design of these glasses allows the wine to be sucked from the bottom of the glass, ensuring that oxygen doesnt come in contact with the majority of the liquid, effectively reducing the oxidation of the wine These small glasses are meant to be held in the palm of your hand, so the wine is slightly warmed and delivered to the correct place on your tongue This set contains a Decanter and 4 Port Sippers in a gift box All items in this set are handwashable only and each 2.75 ounce sipper measures 3.5"H x 1.75"W x 3"D
