I purchased this as a "thank you" for a wonderful Thanksgiving dinner. My friends like and use this item all the time. They tell me it is quite sucessful in keeping leftover wine and are very happy with it.
"Great way to save wine for a couple days." 2009-11-08

I have had a couple of these wine savers, and this one works very well for what it is. I have seen a couple reviews on here commenting that this is not effective and does not create an actual vacuum. While it could never create an actual vacuum, I think it is still effective. A wine will not be perfect the next day, but will still be very good. And where even a good wine will rarely last more than two days once opened, I have experienced very drinkable wine after four days. Of course it all depends on where you start. If it's a $5 bottle of wine then don't expect magic.
"So far, seem to work well" 2009-10-24
By D. Rose (Cincinnati, OH)
Bought this because I saw similar (but not identical) bottle re-stoppers at a Winery, where samples could be tested. Staff could uncork and recork the bottles very quickly for sampling.
So far these have worked well. Stoppers go easily into the bottles. Just have to pull the vacuum handle several times until you here a clicking. Not difficult to pull handle. Also when ready to reuse, just need to press the upper 'stem' on the stopper sideways, vacuum seal is broken and stopper comes out easily. So far working well. People at the winery said you could not use this method for 'sparkling' beverages (champagne) as the vacuum would remove the CO2 (sparkle) - so have not tried with champagne.
"You can create a vacuum with a hand pump" 2009-10-03
By J. Womack
While I don't own this item (I have added it to my Christmas list), I would like to dispel a myth that has appeared in some of the reviews.
As a mechanical engineer who has designed vacuum chambers for over 16 years, I can tell you with great certainty that you can create a vacuum with a hand pump.
Technically, a vacuum is any pressure below atmosphere. If you can remove one molecule of gas with this hand pump you have created a vacuum. If you hear or feel air rush into the bottle when you remove the cork, you have created a vacuum.
The more relevant question is how strong of a vacuum can you create?
Since vacuum is simply a pressure (force/area) less than atmosphere, you can measure the "strength" of the vacuum by comparing the force differential across the pump. Atmospheric pressure at sea level is around 14.7 lb/in^2. If the area of the pump's piston is 1 in^2, you could create a complete vacuum with 14.7 pounds of force. In other words, you could create a complete vacuum with half the force needed to put air in your car's tire. The application of force to this pump is not the limiting factor in creating a vacuum.
The limiting factor will likely be the vapor pressure of the wine.
Due to the kinetics of the molecules in the liquid, there are always some molecules of wine that are ejected from the surface of the liquid. The rate at which these molecules are ejected is a function of temperature. If all the air molecules were removed from the bottle, a vapor would be created in the head space at the vapor pressure of the liquid.
Presuming that the wine was composed exclusively of ethanol and water, its vapor pressure would be around 53 torr or 1/14th of an atmosphere ([...]). The pressure in the wine bottle cannot be reduced below this point as long as liquid remains in the bottle.
A wine bottle opening is typically 18 mm, so a force of 5 pounds would be sufficient to remove all the air from the headspace. It should be noted that air may have diffused into the wine and predicting its extraction is complicated by a time element and potential chemical reactions between the wine and the oxygen. It should also be noted that mixing between the wine vapor and the air in the head space would likely result in some wine vapor being extracted during the pumping process, reducing the amount of air extracted proportionally. This effect would likely produce a first order response that may make it impossible to completely remove all air while wine vapor remains.
I don't how good the seals are on the Vacu Vin, but if it feels like you have to pull with about five pounds of force, you are getting a pretty strong vacuum. Less than 1 pound of force would produce a pretty weak vacuum that would leave more than 80% of the air in the bottle.
Either way, have fun.
