Default Comparing bottle A vs bottle B over a couple of weeks

Hi, I would like to get feedback/comments about the following please:

PROBLEM: I open a bottle every week. I would like to compare the bottle I am opening to the one I opened last week and the week before that. However, the previous week's wine will oxidize so I cannot get a good taste comparison.

SOLUTION: What if I take miniature bottles and fill them all the way to the top with the wine I want to store then it should stay for a few weeks without oxidizing? There might be a tiny bit of air between the top and the cap underside but I can't see that doing much oxidization as there wouldn't be a lot of oxygen in that little gap. Would people agree? Are there other solutions people have tried?

SOLUTION2: Use a vacuum pump to extract air. I have one of these, but 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) -

Regards,
Paul

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 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.
