The Wifey purchased a Coravin as a gift for Christmas. Wow… gadget and wine, all in one. For those of you who are not sure of what this is, here is a photo:

Why Use a Coravin?
Well frankly, I was initially struggling with this idea and did not open the box right away. After a few days, I popped the box open to assemble it and make sure it worked properly. All good… assembles easily, few moving parts. Reminded me a little of those argon gas pumps they came out with several years ago to preserve open wine.
Gave it a try initially on an inexpensive bottle. Didn’t require instructions and very simple to use. The cork self-seals tight, right behind removing the needle. So, the question became: what situation would be right to break-out the device? You hard-core wine-o’s will appreciate my first official use…
New Year’s Eve party at our house. One of my wife’s friends was going on and on about how she hated merlot. Finally, I couldn’t handle it any longer and told her: she just hadn’t tried good merlot yet. Now, you have to understand, here in the USA, 75% of the merlot we produce is some of the worst plonk on the planet. It kills me to think of all the U.S. consumers that think this is what merlot should be (personal campaign of mine)… so, I pulled a 2001 Pride Mountain Merlot out of my cellar and dragged out my Coravin. I challenged her to try it. I served her up a 2 oz. pour of the Pride and rocked her world! Pow! Another merlot hater converted again! AND, I didn’t have to trash an entire $75 bottle of wine in the process!
Science Behind Coravin
Once you pierce the cork (can only be used on cork closures), the lever introduces argon gas under pressure. Then via a two-way valve of some sort, the pressure is maintained, while the wine is forced out of the hollow needle into the glass. Works pretty slick… So, only two potential drawbacks I can envision:
1. If the cork is too dry on an older bottle, either the seal may be lost due to loss of integrity of the cork, or the cork may not show enough resilience to self-seal upon removal. IMO, this possibility does not seem to be very worrisome.
2. My other concern is not serious, but rather more interesting. Once the device replaces the air in the capsule with argon gas, the wine is served and then the bottle is returned to the cellar. Without further oxygen to draw from, the typical wine aging process would have to be significantly slowed, if not stopped. Since argon is heavier than air, the wine may be sealed off from air for the balance of the life of the wine. How does wine age in such an environment? I don’t think there is any research on this??
A very cool device! If you would like to pour a glass while alone, knowing you will be unable to polish off a bottle… PERFECT! The balance of the bottle will be perfectly stored, for the next time you decide to draw a glass, or pop the bottle. I may start drinking more expensive wine, when alone – with no concern for wasting the bottle. If you have a $100 bottle of 20 year old Bordeaux and intend to pour a glass and put it back in the cellar, you may want to think twice. I have no idea how an argon environment will effect the continued natural aging process of high-quality wines in storage.
Science again solves a challenging problem facing our world, preventing the waste of good wine! Next up: reliable hangover relief!
