I recieved a Vacu Vin Rapid Ice pack as a gift last Christmas, and I’m really pleased with how it works. It’s a gel pack that you keep in your freezer, when you need to keep some white wine chilled, or even cool down some red, you simply slip it over the bottle. It keeps the contents nicely cold. I’ve even been known to slip this over a bottle of beer, which can go from sort of cold to ice cold very quickly. Oh look, they even have can sizes, beer bottle sizes and a countoured one for champagne bottles. I don’t particularly like the graphics on the sides, but here is a silver one for wine bottles.
p.s. Why yes, that is a Campari bottle in the picture. We very conveniently didn’t have any wine in the house at the time of the picture taking.
