WINE FREEZE Cooling Cups are perfect for all wines. Each stemless wine tumbler features our proprietary cooling gel which allows the cups to be frozen or chilled to the ideal temperature for serving and enjoying any wine varietal. For red wine, refrigerate the Wine Freeze for at least two hours to keep your drink between fifty-eight and sixty degrees Fahrenheit. For white wine, freeze the Wine Freeze for at least two hours to keep your drink between forty-three and fifty-three degrees Fahrenheit. The Wine Freeze is precisely engineered to keep your beverage perfectly cold for hours. Each stemless tumbler is constructed with an insulated silicone band for comfortable handling, and can easily accommodate 8.5 ounces. Hand wash only. For the best results, place the Wine Freeze upside down in the freezer to allow the gel to evenly spread and freeze.
