Callum saw off competition from five other bartenders from across the UK to take first place.
All six finalists were tasked with creating a cocktail which demonstrated what consumers will be drinking in 20 years’ time.
Callum is said to have impressed judges with his cocktail, Make Tequila Great Again, which combined 1800 Reposado, oak wood smoke, cactus and aloe syrup, lemon juice and Boston Bittahs served in a mug.
His inspiration is said to have come from the notion of global warming, impacting resources of natural water and fresh ingredients, which, in his view, could cause sustainability to come to the fore of cocktails in the future.
Commenting on the award win, Callum said: “It’s an absolute privilege to have been chosen by these judges, and I’m thrilled I’ll soon get to immerse myself in all things tequila in the heart of Tequila itself!”
As the winner of the competition, Callum will receive a trip to Mexico and 1800 Tequila’s distillery.
