Looking for an extraordinary pour this New Year's Eve? Bid on the world's priciest miniature cognac bottle at Catawiki this week. This 5cl Henry IV cognac is housed in an exquisite 18-karat white gold vessel adorned with 2,800 precious stones, carrying an estimated value of €150,000. That puts the cost of a single sip at around €50,000. The seller, a renowned Mexican collector who holds the Guinness World Record for the most expensive bottle of water, is offering it for the first time ever. The auction concludes on Boxing Day.
