Special note: the vacuum plug of good quality， fast pumping air into vacuum state， but because of appearance design， can\'t do all the red wine in general， can only be used for wine bottle diameter less than 18.5 mm or less (test bottle is very simple， if the vacuum plug is very loose into the bottle， that bottle is too big， if you plug in a tight means that bottle is appropriate， generally have the chance of a few percent，).
