Last night my Junior League committee had a holiday gift exchange. While there were lots of cute and yummy gifts, the hit of the night was a Corkcicle. This crazy looking icicle will keep your wine chilled for hours. It's made of reusable gel and all you have to do is freeze it for a couple of hours and then stick it in the wine bottle after pouring one glass. Voila! No more messy ice buckets or making trips to the fridge to refill your glass. When you're done, rinse the Corkcicle off and store it in the freezer for your next round!
Also, I recommend having a wine freezer bag handy. They are great for toting a bottle of bubbly or wine while keeping it chilled.
