Hi there. Last evening I grabbed a bottle of X wine but when I popped the cork I immediately realized that it was not the bottle I had intended to open (very similar bottle shape and foil). I shoved the cork back in all the way and put it back into the cellar. FWIW this is the 2019 Sandlands Nebbiolo. My question is, how long did I just alter its ability to last?
You might want to contact the winery and ask them. They will have a better idea based on how it was bottled and maybe experience. Without knowing more, it seems you let in a significant amount of oxygen that is still in the bottle. It is probably good for a few months, but if it was me, I would always be nervous about it. I think I would pop that cork again on Saturday morning and drink Saturday night. It might be different if it was Mourvedre or Syrah but California Nebbiolo is different. Still, I would call them first.
Once it’s opened, it doesn’t matter if you cork it back up unless you add some sort of gas filler to displace the oxygen. Even then you only extend the life a bit. I would treat it like any other opened bottle - store in the fridge and drink in the next couple of days to maybe a week if you want to push it.
I also wonder about any wine that you can recork all the way. That typically indicates a poor seal/poor quality cork, which exacerbates the problem further. Any cork that’s actually creating a full seal will not be able to be inserted completely without a vacuum due to the air in the head space.
Also, likely unproductive. Highly doubtful that you’d get someone on the phone (small, independent winery with no tasting room). Any answer would be mostly speculative, and they’re not going to tell you that the wine is guaranteed to last for any length of time.
My question isn’t what should I do with the wine, and I am certainly not stressed about this situation. I am asking what happened to it’s aging curve when I immediately replaced the cork. Has anyone done this and drunk the wine several months or a year later?
Let’s see, you introduced a couple cc (at most) of new air, 20% of which is O2. Unless the wine is something older, and quite delicate, I would think there’s a pretty good chance it will be fine long term. Unless it’s something really valuable, I’d treat it as a fun experiment, put it away, and see how it turns out years from now. Mark the bottle so you remember.
Oh, now I see what it is. Hell yeah, put it away and see how it turns out
