The new KAGURA decanter will change how you enjoy wine, sake, or olive oil. Simply pour a bottle of wine into the decanter and place the floating lid on top to exclude about 97% of the air contact surface. As a result, oxidative deterioration is delayed two- or threefold, so there is no need to consume the product quickly or waste the last portion. Potential consumers are those who would like to drink a glass of fine wine daily for health and beauty but don't want to buy a full bottle because of wastage.
