Zork technical information & independent testing
The ZORK PopCap is a market driven, technical solution to the wine industry's greatest challenge: how to close the bottle without spoiling the wine. The primary function of the three components are:
Provides a tamper evident clamp that locks onto the European CETIE band of a cork mouth bottle
Provides an oxygen barrier similar to a screw cap
Creates the 'pop' on extraction and reseals after use
All materials are FDA and EEC approved and are fully recyclable.
Zork made an independent test for their Zorks :here is the summery of the 12 month test.
