Comparing bottle A vs bottle B over a couple of weeks

not sure I trust it since I cannot believe it truly extracts all the air out of the 750 ml bottle. From what I recall from physics (its been awhile!), to truly create anything near a true vacuum would require an overwhelming amount of force.

Thoughts would be most appreciated. Please cc: me on the replies (removing the uppercase) - snipped-for-privacy@comcast.net

I'd go with solution 1. I've never thought vac-u-vin very effective. If I know I really am not going to drink more than 1/2 a bottle over a couple days, I immediately pour half into a clean 375 and recork. Wine holds a week or two quite well. Same would obviously work with 187ml bottles.

I recently read where someone does the same thing, but adds a few drops of a 2% solution of potassium metabisulfite (did I get that right?) -seems more complicated than needed to me, but ingenous.

The other idea would be a commercial heavy gas product, i.e. Private Reserve.

Private Reserve is nitrogen IIRC. Nitrogen is _lighter_ than air (but not by much).

I agree.

That's very interesting, thanks for sharing. I'm not sure why I never thought of it. It wouldn't take much Potassium Metabisulfite to scavange the O2 picked up during transfer or left in the head space of the new bottle. Since I usually have some K. Meta. solution on hand, it really wouldn't be any more complicated than just transfering the wine.

I have my concerns about the effectiveness of this especially after the discussions we've had here and on RCW about gas dynamics.

I thought air was a mixture of roughly 80% nitrogen with 20% oxigen. How can one be ligther than the other?

Nitrogen is the llighter component of air (lighter than the oxygen) this is so the same as water is lighter than alcohol even though they mix.
