With the Zwilling Sommelier wine decanter from Zwilling, you can pour a well-aerated wine and then use it to reseal the bottle so that the wine's flavour is preserved. The product is simple to use and fits all bottles. It has an inbuilt spiral system that allows the wine to mix with the oxygen in a unique way as it flows out of the bottle. This makes this wine pourer a must-have for anyone who wants the wine's character to be brought out to its full potential.
