How to make the perfect Margarita at home

Tequila Tromba was launched by two Aussies and a Canadian – Eric Brass, Nick Reid and James Sherry – who met in Guadalajara, Mexico, back in 2005 and developed a love of pure agave based tequila. They set out on a mission to turn people from shots with lemon and salt to sipping and savouring the good stuff.

They found partners in Master Distiller Marco Cedano and his son Rodrigo. Among Mexico’s tequila artisans, Marco is regarded as a true pioneer – the first master distiller to produce premium 100% agave tequila. The Cedano family’s passion for making great tequila has been passed down from father to son in the highlands of Mexico. Now the two generations of distillers are lending their expertise to Tromba’s creation.

When it comes to making the world’s most popular tequila cocktail, the Margarita, Sherry says the secret to mixing a bar-quality drink is in the ingredients.

“My top tip for making the perfect margarita at home is to start with the best quality ingredients you can get,” he said. “Quality 100% agave tequila is a must, as is fresh lime juice. Your cocktail making skills may not be professional grade (they will be with practice!) but there’s no reason why your ingredients can’t be.”
