Wine Saver
You know how many times I wanted to open a bottle of wine just to have a small glass or to use only 100ml for cooking... but I stopped because it felt wasteful to sacrifice a good bottle of wine for so little. That changed a few months ago when I discovered this lifesaving tool that creates a vacuum in bottles, slowing down wine oxidation.
The set consists of a pump and several rubber stoppers. The pump extracts air from the opened wine bottle and reseals it with the rubber stopper.
