Whether you want to quick-chill a glass of warm white wine or rosé, or keep it chilled as you sip, there's a simple solution — and it does not involve ice cubes (keep those in the freezer, please).
Instead, keep your glass of wine chilled with a few frozen grapes! Not only are frozen grapes a refreshing snack, but they do wonders for chilling otherwise warm drinks. And unlike ice, which will start to water down your wine in a matter of minutes as it melts, grapes work to chill your drink without diluting it.
Of course, you can use any type of frozen fruit, but what makes grapes such a great choice is the layer of skin that surrounds them, as well as their tiny size. So while other fruits, like melon or berries, may release their flavors into the wine, you won't get that with grapes — the skin keeps their mild flavor sealed on the inside of the fruit.
And when it comes to sangria, you're already adding fruit. Why not skip the ice cubes, and load up the pitcher with frozen grapes? It looks nice, and you'll get more flavor.
