The research and multiple audits carried out in many cellars by Vinventions have revealed the importance of the headspace when it comes to managing oxygen during the bottling process. Although the volume involved is small, this space contains on average 65 % of the TPO (Total Package Oxygen), causing, among other things, the rapid loss of free SO2 and an increase of the color. Effective headspace inerting is therefore crucial to preserve wine quality, especially when screw caps are used and the headspace is between 2 and 3 times greater than for cylindrical closures. The NomaLine HS 6000 has been developed to respond to these needs and, thanks to a patented system involving the double injection of inert gas, headspaces can be inerted effectively, achieving oxygen levels as low as 5 %.
