This 100-year-old Cognac is one of the rarest and most expensive drinks on the planet carrying a $2 million price tag. It comes in a 24-carat gold and sterling platinum bottle scattered 6,500 diamonds made by jeweller Jose Davalos. The expression itself was first produced in 1776 and was named to honour King Henri IV. It is aged in barrels for more than 100 years and just 100cl is decanted into the 8kg diamond studded bottle.
