The study, which took place in five major European markets (France, Germany, Italy, Spain and UK) and the US, was commissioned by the European aluminium closure manufacturers and suppliers who are members of the EAFA Closures Group, part of the European Aluminium Foil Association (EAFA).
Aluminium closures also scored top when consumers were asked about their preferences for re-closing a bottle of unfinished wine for later consumption. Four out of 10 surveyed said they had poured away wine from a bottle closed with a cork closure that had been tainted or gone bad.
In markets where aluminium closures have a lower market penetration, there is less understanding of the convenience offered by them. Yet, even in these countries, the majority responding accepted that aluminium closures offer a more convenient option for re-closing than corks or other types of closure.
When asked to compare their purchasing intentions of the same bottle of wine with different closures, more than a third said they would prefer to buy wine with an aluminium closure, and a quarter said the type of closure wouldn’t influence their purchase.
Only 30% of consumers connect ‘easy and complete recyclability’ with aluminium closures. This supports the industry’s continuing efforts to more proactively promote the advantages of recycling. In Europe, more than 40% of aluminium closures are recycled.
Finally, the survey showed that, among younger consumers and particularly females, there is a strong preference for aluminium closures.
