AU Vodka founders say Trump tariffs would only speed up US plans

“Remember, we sat in a McDonald’s and just wrote [the plan] on a napkin,” Mr Quinn said.

He remembered thinking “if everything goes our way, with the wind in our sails, we’d do £3m of sales which would be huge revenue for us”.

“But then fast forward 12 months later, I think we did £38.4m,” he added.

It was, Mr Quinn said, “a crazy, crazy twelve months”.

Mr Morgan said the gold theme and a marketing blitz told just half the story of the drink’s success.

“That only gets someone to try it once,” he said.

“The next – and most important – part is, is the liquid any good?

“If the liquid isn’t any good, then people won’t come back the second and third and fourth time.”
