Comments on: How long does leftover wine keep in the bottle? Wine-preservation myths and a simple solution http://blindtaste.com/2009/05/25/how-long-does-leftover-wine-keep-in-the-bottl/ A critical review of food, drinks, culture, and cognition Wed, 10 Mar 2010 17:44:50 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: J Smith http://blindtaste.com/2009/05/25/how-long-does-leftover-wine-keep-in-the-bottl/comment-page-1/#comment-4129 J Smith Mon, 09 Nov 2009 22:16:01 +0000 http://blindtaste.com/?p=363#comment-4129 The vacumn systems don't work, the sparge systems don't work. The gas systems DO work. Why? Because the wine bottle isn't left open and isn't exposed to oxygen. Open it and leave it open -changes the quality no matter what -that might be a good thing. Proven technology over 25+ years old. By the way, they use inert gas when racking at the winery. Not so much of a myth anymore, eh? The vacumn systems don’t work, the sparge systems don’t work.

It seems to me that you're removing the contact with air in both cases. As to the gauges that fail over time, I have tried the "V Gauge" which has a dial on the top which supposedly shows the vacuum strength. I've seen it hold the same level for up to 5 days. I don't think I've tried it longer than that. What the opinion on the wine preservation techniques chosen depends on the "quality" of the wine?

The only wine subject more dominated by malarkey is aerators. Apparently Guy Stout at co did a blind tasting with ten different aerators and the overwhelming conclusion was that most of the aerated wine tasted worse than the fresh control. I would love to see ya'll put these questions to rest with a comprehensive study... Please please please organize a really thorough, scientific blind tasting on wine preservation techniques.

I wouldn't find it satisfactory having a jumble of different bottles or boxes to keep control of, so prefer to keep in the original bottle. And as you say, it is a matter of degree - many wines do improve with some exposure to air, so if I drink half the bottle and vacuum out most of the remaining air, sure, the wine will taste a little different to a skilled palate, but it tastes just fine to me. I find vacu-vin doesn't work if you try and keep something for a long time (+1wk) as the vacuum gradually fails. I’ve owned a vacu-vin for years and really do find it satisfactory.

That won't make the wine taste much better... Dry ice is no option: a part pf the carbon dioxide will dissolve in the wine to form carbonic acid. That won’t make the wine taste much better…

As the solid CO2 sublimates and changes into a gas, it will fill up the bottle and displace the oxygen, since CO2 is more dense than O2. You would want to wait until the ice is fully transformed into gas before recorking, of course. CO2 is less reactive than O2, which would help prevent those bad flavors. Would potentially freezing a small portion of the wine effect the taste? This may be a bit on the geeky side, but what about dropping a small piece of dry ice into the bottle?

It's absurd that the wine industry packages its product such that customers can't easily consume the amount they want. Wine drinkers should reward wineries that off the box option (by purchasing their products) and encourage others to do so. As you imply toward the end, the real solution here is wine boxes.
