Wealthy tequila aficionados who have grown tired of knocking back shots in a messy bar or sipping premium blends in the same old surroundings can take their love of the spirit to luxurious new heights.

For the eye-watering sum of $500,000 (£325,000) a group of up to 10 people can board what is being touted as the world’s most expensive tasting flight.

Offered by Tequila Avion, the half-a-million dollar travel experience allows guests to sample the company’s products on a Gulfstream private jet in the skies over Mexico.

A professional photographer will be on board to capture every moment as passengers sip tequila at 30,000ft during the one-of-a-kind experience.

In addition to the flight, guests are taken on a private tour of Tequila Avion’s distillery in the south-western state of Jalisco with company founder Ken Austin.

Before the trip ends the group is treated to dinner at the home of master distiller Alejandro Lopez with chef Josh Capon from the New York City restaurant El Toro Blanco.

The experience also includes some tequila for the road, as guests will leave Mexico with bottles of never-released tequila from Mr Austin’s personal collection.

They are also given the opportunity to age their own private small batch of anejo tequila for at least two years.

The bespoke trip includes a private butler, security detail and rooms at the five-star Las Alamandas resort on the Pacific coast for three days and two nights.

Tequila Avion – whose brand was once featured in the HBO series Entourage – launched the offer on May 5 (Cinco de Mayo). Avion is the Spanish word for 'plane'.

Mr Austin said in a statement: ‘As an ultra-premium tequila brand, Avion aims to constantly challenge standards of quality and luxury.
