Skyy Vodka has unveiled a limited-edition can format for its pre-mixed soda and lime expression, which features an engagement ring in place of a ring pull.The new can format, called Skyy Vodka Yyes, has been launched to celebrate equal marriage rights in Australia, after same-sex marriage laws were approved by the country's government in December last year. The design features rainbow-coloured text and an engagement ring in place of a ring pull, a ‘world first’ in the pre-mixed drinks market. Nicole Stanners, marketing director for Skyy Vodka, said: “At Skyy we believe diversity should be celebrated. "We are incredibly proud to celebrate marriage equality in Australia with the launch of the new Skyy Vodka Yyes can, especially if it’s encouraging loved up Aussies to get hitched!” The Campari-owned vodka brand announced that AU$1.00 from the sale of every Yyess product will be donated to the Just Equal organisation, which aims to support members of the LGBTI community in Australia through lobbying and social media campaigns. Ivan Hinton-Teoh, founder of just.equal, said: “We are proud to once again stand together with Skyy Vodka to show our support for equality and diversity in Australia. "The marriage equality campaign has gone from strength to strength, and with the support of Skyy Vodka we can keep up the momentum so that sooner rather than later, LGBTI Australians can enjoy true equality.” The limited-edition cans of the Skyy Yyess Soda and Squeezed Lime cans will be available from Gazebo, Elizabeth Bay and Liquor on Oxford, Darlinghurst until 31 March. Yesterday, Skyy Vodka producer Campari reported that its 2017 full-year sales increased by 5.2%, bolstered by key global brands Aperol, Campari and Wild Turkey.
