Review on 🍷 Savino Wine Saver Preservation System: Shatterproof Airtight Decanter Carafe | Keeps 750 mL Red and White Wine Fresh for 7 Days | Ultimate Wine Gift | Made in USA by Phil Kowal

I have used this carafe for several months to store open bottles of red and white wine. At first glance this may not seem very efficient compared to vacuum devices which remove most of the air. In this decanter, the gap between the perimeter of the floating cork and the inner perimeter of the decanter is about one millimeter. This allows the air to come into contact with the wine. However, the wine keeps for a good four to five days and in some cases tastes better on the last day than on the first. Good wines need ventilation to develop. I think it works by limiting air exposure so that with limited air exposure the wine opens around day four. fully. After opening the bottle, I fill the contents completely into the carafe, then pour into glasses as required and let the freshly opened wine air out in the glass. The remaining wine is aerated in the carafe for several days.
