Review of the Wine Industry’s ‘International Standard Screwcap’ – Production, Materials, Variations

Location: Adelaide, SA

Duration: 3 months

Proposed start date: June 2019

Project Background

The ‘international standard screwcap’ (screwcap) is currently used to seal the majority of bottled wine produced in Australia and New Zealand. The existing design (aluminium with saran/tin/PVDC insert) was introduced in 2000.

A wine authentication system involving QR codes and blockchain (being developed by G & T Technology Pty Ltd) wishes to determine whether this screwcap design is the most up-to-date option on which to base its wine authentication platform. Whether recently offered variants of this screwcap have been adequately assessed to determine the impact on wine quality needs to be determined. In addition, stricter health and environmental regulations may soon impact the standard screwcap design.

Research to be Conducted

A thorough review of materials and methods used in the current screwcap construction to determine if this design is the most up-to date available. This will include a critical assessment of all aspects of recently introduced screwcap variants to determine if one is more suitable for this purpose. This review will include cost, performance as well as potentially relevant international legal, environmental and health considerations.

Skills Required

We are looking for a PhD student with the following:

  • A material or chemical engineering background
  • Knowledge of materials, their qualities – suitability (malleability /permeability, resilience, long term resistance to fluids of moderate acidity and possible associated by products/health considerations.

Expected Outcomes

Determining the relative suitability of the screwcap in remaining the dominant closure for bottled wine in this country. Assessing if the screwcap is suitable for adoption in its current form to become part of the authentication system being proposed by G & T technology. Thorough assessment of existing variants will determine if they are more or less suitable due to cost, performance, environmental, health or legal issues. The third outcome option is a new design based on materials currently not utilised in any of the commercial options assessed.

Additional Details

The intern will receive $3,000 per month of the internship, usually in the form of stipend payments.

It is expected that the intern will primarily undertake this research project during regular business hours, spending at least 80% of their time on-site with the industry partner.  The intern will be expected to maintain contact with their academic mentor throughout the internship either through face-to-face or phone meetings as appropriate.

The intern and their academic mentor will have the opportunity to negotiate the project’s scope, milestones and timeline during the project planning stage.
