Specialist contract packer and container glass manufacturer Encirc has said that it has achieved record total packaged oxygen (TPO) levels in its 2.25 litre bag-in-box packaged wines, following a multi-million pound investment in its advanced filling technology.
Independent analysts have verified that TPO levels in Encirc’s bag-in-box wines are consistently below 3mg per litre – a benchmark that experts have claimed only the highest performing production lines can achieve.
The results are down to Encirc optimising filler performance, as well as processes used in the bulk shipping of wine from overseas, which has helped to minimise the levels of dissolved oxygen present in the wine prior to packaging. In addition, headspace volume in Encirc’s bag-in-box packs is now around 21ml – well below the 34ml maximum recommended by experts – further reducing oxygen levels.
Minimising oxygen content in packaged wine is a crucial goal for producers, as it reduces the need for additions of SO2, which has the effect of supressing taste at high concentrations, Encirc said.
Encirc oenologist Henry Powles explained: “Optimising the processes we use to manage the levels of oxygen in the wine we package for customers forms a key part of Encirc’s ongoing investment in enhancing our service and product quality.
“In doing so, we can ensure their products taste great and stay fresh for longer, so they can provide end consumers with the best possible drinking experience.”
