The Wine FREEZE™ is perfect for all wines. Just pop it in the fridge to cool your reds to the perfect cellar temperature or store in the freezer to chill your whites. HOST®'s proprietary cooling gel is precisely engineered to keep your beverage perfectly cold for hours. Refrigerate for red wine; freeze for white wine. Hand wash only. For best results, place in fridge/freezer upside down to allow the gel to evenly spread.
