Anyone have a coravine wine opener?

No.

No.

If you own a restaurant pouring super high end wine by the glass, it could make sense. If not, total waste of money.

So I like to have a bottle and drink a couple glasses with weekday dinners for a couple weeks. So if a bottle could last 3 weeks it would be worth $200.

gzus, just buy a waiter's friend to open the bottle and a vacuvin to seal it up. I'm talking $12 total instead of $400 and it does exactly the same thing.

Is the bottle of wine you are opening for these casual weekday dinners a bottle of DRC? If it’s a $20 bottle of wine you aren’t saving $200 by prolonging it for a few weeks.

My wife gave me one for Christmas a few years ago. I used it for a while, but I didn't find it particularly useful. For my purposes, the best application for it would be to drink a glass from an older bottle of wine without opening the bottle. But given that the device injects an inert gas into the bottle, it stirs up the sediment in the bottle, which basically screws up the wine, so it wasn't really good for that purpose. I also did a few experiments to see if I could take a glass out of an expensive, but relatively young bottle, then opened the bottle a few months later to see if it was still fresh. It wasn't. So I didn't find it particularly useful.

Same experience. It’s a good idea in theory but it’s simply non consistent and you end up potentially ruining a very expensive bottle of wine.
