Bluff Distillery’s Bluff London Dry Gin won the accolade for best in show, judged over seven categories.
It also won its dry gin category.
Co-founder and distiller Chris Fraser said it was an honour to be recognised on the international stage for a gin that represented the ruggedly beautiful spirit of Bluff.
"It’s great validation for us as a team.
"Just as everything else in Bluff - the gin is what it says on the tin.
"We wanted to make a gin that respected the classic London Dry recipes created hundreds of years ago... A bit like Bluff, we decided to stay authentic to the heritage of gin so it’s great to see our strategy - to stay true to who we are - has been recognised by the judges."
Co-founder and brand director David Nash said the award was a particularly stunning achievement, given the brand was launched only in March.
The first batch sold out within five days, he said.
"There’s something remarkable about winning a trophy in Australia for a classic London dry gin distilled in Bluff, 19,000km from the UK."
Co-founder Blair Wolfgram said the award would give them even more confidence on its plans to increase production by 100% to 150% in the coming year.
"Taking Bluff’s story to the world and bringing the world to Bluff is incredibly exciting."
