The Winesulator™ is the perfect example of a good, simple and efficient design. This 750ml stainless steel bottle is meant to keep your wine cold during transportation. You simply leave it in the freezer between uses, and when the time arrives, you pour the liquid directly into it, using the very useful funnel it comes with. But it doesn't stop there! As cocktail lovers, we strongly recommend to use it as a pre-made cocktails vessel. Let's say you are invited to someone's house for dinner, and you don't feel like spending so much time picking the perfect bottle of wine. But making cocktails at someone else's house can be tedious. You have to carry your bar tools, your ingredients and your bottles. The Winesulator™ makes everything easier! You just make a couple portions of your cocktail, pour them in the bottle, and all you'll need is ice and maybe sparkling water. Also, think about how much fun an afternoon in a park could be with this lovely item.
