The shelf life of wine is often markedly reduced by the ingress of atmospheric oxygen through the valve or spout. The principal objective of this study was to evaluate various types of valves by means of a capture cell which provides the flexibility to evaluate performance under three possible ambient conditions (23, 30 and 38°C). With the basic statistics obtained we were able to estimate a data confidence interval (95%) and suggest predictive equations useful to buyers in the industry.
