ZORK Closures - The New and Better Wine Closure - Cork. NO CORKER OR CORKSCREW REQUIRED! Originating in Australia, ZORK Pty Ltd was founded specifically to develop alternative closures for wine and spirits. ZORK STL (for still wine) is a patented, alternative wine closure that solves the problems of cork taint and random oxidation for still wines. Winemakers have embraced the convenience and quality of ZORK closures (no corking device to insert and no corkscrew required to remove). This alone makes them perfect for 375 ml (split) bottles popular for wedding, baby showers and other venues where party favors are desirable. The overwhelming response from wine makers to ZORK STL is that they love the convenience of being able to bottle their wine or party favors without the use of a corking device and then open the bottle without a corkscrew while retaining the traditional pop! ZORK STL is also suitable for use with fortified wines, spirits, high volume alcohols, other beverages and food products. The materials used have been extensively tested and the closure has met, and in many instances exceeded, the industry benchmarks for wine bottle closures. NOTE: Zorks only work properly with OUR 375 and 750 ml cork finish bottles. They DO NOT work with 187 ml or 1.5 liter bottles of any kind. If in doubt please call us at 574-295-9975. As always, leave your bottle upright for at least 3 days before lying down. Zorkd bottles may stand upright at all times. Estimated shelf life for still wine is 4.2 plus years.
