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
