MARK Wyatt, better known as Dr Rum of Airlie Beach's Rum Bar, is once again making waves in the Australian rum industry, this time judging the Angostura Global Cocktail Challenge heat in Brisbane.

The challenge is designed to find the next classic cocktails using Angostura rum and bitters.

It's held every two years and the national winner gets $10,000 and is named the Angostura ambassador for a year, before zipping off to Trinidad for a chance to be the international winner and a global ambassador.

This wasn't Dr Rum's first rodeo, with Brisbane heats held the day after International Rum Day on August 16.

"Australia has won this competition more times than any other country, which is great for such an amazing global competition," he said.

After a night of serious judging, two cocktails made the grade - the Chevron Stinger, named after the deadliest spider in Trinidad (home of the rum), and the 868, which is the dial code for Trinidad.

"I was very much honoured to be asked to judge this competition. I have been involved with judging global rum competitions for years now, including Bacardi Legacy, mostly off the back of our award-winning rum bar and being crowned Australia's rum ambassador," Mr Wyatt said.

"It is a chance to see the cutting edge of the Australian cocktail and rum scene."
