Review from Chening K.
Put the cap on the wine. Put the pump on the cap. Pump the pump. It is as simple as that. Wine tastes good tomorrow, next day, next week. We are not very sophisticated wine drinker but our wine tasted as good as when you opened the bottle. The pump removes the air and keeps the wine from oxidizing. This product is good if you have a party and not all the wine was consumed. Just pop this top on it and pump the air out and you have fresh wine for the party next week.
