Every post on this board is a “first world” post, duh
A couple additional comments.
I’ve noticed sometimes wine will drop a little over a couple of days after using the coravin so I would do your sampling a week or more before your trip to make sure the corks have sealed back up.
Make sure you don’t leave any extra gas in the bottle (i.e. let your pour drain out completely before releasing the button).
As someone else mentioned, use those wine traveler sealable bubble wrap bags just in case a few drops leak out.
Agree with others this shouldn’t be a problem and would be interested to hear how it goes. No need for a “control” set of bottles as most of us have traveled with wine without any issues.
I always send bottles via UPS ahead of me to hotels a week or so before I get there. I routinely coravin bottles to be sure I’m not sending anything corked or premoxed. Never had a single issue, even with 30 years of age.
Mike, I suspect you will be fine. My only concern would be if a lot of the wine were removed and exchanged for Argon, leaving a greater relative amount of gas in the bottle subject to Boyle’s law. Maybe that could pop a cork at altitude. The tiny taste you are mentioning, I highly doubt would be a problem. I don’t see the cork leaking from the hole as a real fear. Your idea of tasting it via Coravin has never occurred to me before, but I like it. Good luck!
To start I always stand the bottle up a week or two before, giving it a hard bang to try and dislodge any sediment on the sides. Then just pour carefully and slowly. If it’s only a glass never had any sediment. If you’re talking half the bottle no way to prevent it.
