Jon and Sarah Lark held a celebration at Kangaroo Island Spirits on Saturday night to say thank-you to those who made the business such a success over the years.
The Larks recently sold the business to publicly listed company Founders First, which recently rebranded itself as Mighty Craft.
Representatives from the company flew into Kangaroo Island from the head office in Melbourne to join the celebration on Saturday.
Also flying in were musicians Mick Thomas and Mark "Wally" Wallace of the legendary Aussie band Weddings, Parties, Anything, who provided the entertainment along with local musician Scott Ellson.
Mr Lark said the success of the business was the result of all the work and passion put in by everyone from the people in the packing room to the distillers to the gardener.
"The culture of this business is what translates into at the end the highest quality of the product," he said. "The culture is everyone here so thanks for coming. It's been a great journey and you've been part of it."
Employees who had worked at KIS from the very beginning when it opened in 2008 were invited to the celebration.
Sarah Lark said she and Jon were happy with the transition and were now looking forward to be able to focus on the gin instead of all the other aspects of growing the business.
Kylie Bamford, formerly of the KI Tourism association, is now head of operations on site.
The development will be completed in two stages, starting with the construction of a world-class distillery.
A third still will be added to increase the production capacity for the domestic and export market of the award-winning gin, vodka, and the soon to be released single malt whisky, the first for KI.
The second stage of the masterplan will introduce a commercial kitchen and potential plan for accommodation to cater for the overnight market.
