IT’S a dram fine collection – and Guinness World Records agrees.

A Vietnamese connoisseur has made it onto the list of the globe’s biggest and greatest with his whisky collection, which is the most valuable in the world.

Viet Nguyen Dinh Tuan’s 535 bottles of the finest, rarest, oldest Scots and Japanese varieties are worth at least £10.7 million according to Fife experts Rare Whisky 101, who appraised it for the record bid.

If it were to go under the hammer at a UK auction house, this would rise to £13m, the Dunfermline team claims.

This is because it includes one of the world’s only complete Macallan Fine & Rare collections and the most expensive Bowmore ever made.

Andy Simpson, co-founder of the firm, said he was “gobsmacked” by what he found.

Individuals bottles in the Ho Chi Minh City man’s dedicated whisky room are worth hundreds of thousands, with one likely to make £1.2m at auction.

The businessman, who started collecting 20 years ago, says it is his “life’s passion”. He explained: “Every spare I moment I get, I’m searching auction sites and trading websites to find famous and rare whiskies from around the world. Clearly this requires a lot of patience and no shortage of tenacity, but I’m proud of my efforts.

“As for my collection, I have no intention of selling any of it – not one bottle. In fact, I’ll continue to hunt for more old and rare bottles and add to and enrich it.”

However, Viet said that he had been “surprised” to make Guinness World Records, adding: “I’m really happy and feel honoured to be recognised by Guinness World Records as the owner of the world’s most valuable whisky collection. It feels like an acknowledgement of all my hard work and dedication.”

Simpson said: “We were somewhat gobsmacked, not to mention a little envious, when we realised the breadth and depth of Mr Viet’s collection. It’s a truly stunning example of one person’s 20-year passion.”
