    <title>An Innovation in the Wine Closure Industry:
Screw Caps Threaten the Dominance of Cork</title>

    <abstract>Cork stoppers became the industry standard for wine bottle seals probably going as far back as the
1600s. Manufacturers of alternative wine bottle seals have made several attempts to wrest market
away from cork manufacturers, particularly over the last thirty years. In spite of these efforts, cork
remains the dominant wine bottle seal, with a market share of around 90 per cent.
This paper examines the threat to cork manufacturers of one innovative product, the screw or twist
top wine seal. Developed in the late 1950s and thoroughly piloted and tested in the market in
Australia in the 1970s, the screw top seal was largely a failure, despite the commitment of a group
of Australian winemakers to what they believed was a technically superior product. While
Australian wine makers abandoned the screw top experiment in the early 1980s, a second attempt
by a small number of wine makers from the mid 1990s has captured the attention of the wine
industry internationally due to its initial success.
What unfolds in this paper is a fascinating story of a product that on many performance attributes
outperforms the cork seal, but has so far failed to gain mainstream market acceptance from retailers
and end consumers. Although there have been scores of articles in wine and food magazines that
have discussed the merits of cork versus alternative seals, we are not aware of any literature that has
evaluated the contest through the lenses of innovation theory. In so doing this paper analyses why
the initial product launch of the screw top was unsuccessful and why the recent second attempt may
indeed be a turning point for the screw top wine bottle seal.
The paper is divided into five sections. Section one provides a brief overview of the nature and
history of cork as a wine seal. The growing dissatisfaction with cork as a wine seal is outlined in
section two. Section three provides the background to the development of the screw top wine seal
and its launch in Australia. In section four we explore with the aid of technology adoption
innovation theory why the launch was a failure. We then outline in section five the second recent
attempt by Australian wine makers to gain market acceptance for the screw top. We will see in this
section there are a number of factors that have changed between the first launch and the second
launch. Section six focuses on the question as to whether the second attack on the industry standard
will be successful.
We conclude that innovation theory can both explain why the first launch failed and why the second
launch may indeed be successful in the long run. In particular, Moore&apos;s (2001) adaptation of the
technology adoption life cycle model, although originally developed from experience in hi-tech
industries, aided in understanding the key reasons for the initial failure of the screw cap and also in
predicting the early success of the screw cap&apos;s second attack.</abstract>
