Research over the last 30 years has proved to successfully preserve and protect the aroma, taste and appearance of a diverse range of types, styles and ages of wine; the preservation method must achieve optimum preservation every time. The tolerance for achieving optimum preservation is as tight as +/- 1 degree.
Effective still wine preservation minimises oxygen contact with wine to slow down oxidation. Effective sparkling wine and champagne preservation focuses on minimising the loss of delicate CO2 bubbles, research has shown that champagne's bubbles contain aroma and their loss diminishes flavour dramatically.
Effective wine preservation is an exact science; many home style gadgets have been produced over the years, promising a lot and doing little to deliver. Effective wine preservation systems need to be engineered to tight tolerances to deliver effective wine preservation.
