If you've never heard of the Coravin, just take a quick Google and you'll find tons of folks waxing poetic about the high-tech wine gadget they can't live without. Last year, Food Network fans were among many other Coravin lovers on Prime Day and Black Friday, purchasing more than 500 units in just one day. So what is this magical gadget? Here are the highlights.

It'll Save Your Wine for Months — Maybe Even Years.

We know, we know. Who really opens a bottle of wine to only have one glass? Well, look at it this way, if on Monday you're craving red and Tuesday your dinner pairs well with Chardonnay you don't have to worry about finishing the bottle of red by Wednesday if it turns out rose is in your future. The Coravin uses a surgical grade needle to syphon out a glass or two of wine without corking the bottle. That means, no oxygen is coming into contact with the wine, preserving it for months to come.

We Love It for Dinner Parties.

Seriously, it's a great party trick. Pour your guests a glass of whatever they prefer and watch their jaws drop when you flip the bottle over without a single drop leaking out of the cork. It's a fun way to dip into a variety of bottles without wasting any wine.

You'll Save Money.

This depends on the kind of wine drinker you are. If you find yourself with multiple half-drunk wine bottles at any given moment, this gadget will keep you from having to throw away wine that's turned. However, if you open and finish a bottle no matter what, this might not be for you.

Rare Wines Aren't So Intimidating Anymore.

If you've ever received a super-expensive bottle of wine, you know what a big deal it is to actually uncork and drink it. The Coravin takes the anxiety out of that allowing you to have a single glass or taste without needing to finish the bottle in one sitting. That's why restaurant owners love this gadget for giving their patrons a taste of their most exclusive bottles.
