The statement on the packaging makes some bold claims, that zzysh® ensures that your sparkling wine retains it's quality, even weeks after the bottle was first opened. Glass after glass."
The unique technology replaces the air in the wine bottle or pressurizes it, if it’s sparkling wine. This with a highly pure protective atmosphere consisting of argon for wine or a mixture of argon and carbon dioxide for sparkling wine. In combination with the stopper, this works to protect the wine and sparkling wine from oxidation, ensuring flavour, taste, fizz and colour are all retained.
The packaging and product are incredibly attractive and elegant. I found it very simple to use, and the instructions were very straightforward. You unscrew the main unit and screw the little gas bottle into place. You then place the stopper on your bottle, clip into place, and press the gas handle on top for 3 to 4 seconds. You will hear a "zzysh" sound, telling you that it is complete. That's it - your fizz is sealed and will remain fizzy - that simple.
I have tested this out firstly over a 24 hour period, then also 7 days, and when you take the seal top off the bottle, it pops like when you first take the cork out - this genuinely works! They also have a stopper for red and white wine too - if you haven't finished the bottle. They are different for wine and the zzysh® Wine cannot be used for champagne and vice versa.
