And finally… the angel investor’s share

Matthew Robson, 28, was given the Macallan single malt by his dad every year, with strict instructions never to open it.

His father Pete, who is Scottish, told the BBC: “I thought it would be interesting if I bought one every year and he’d end up with 18 bottles of 18-year-old whisky for his 18th birthday.

“It wasn’t the only present he got from us. It was just meant to be a unique present but it was a little bit of luck that we kept it going.”

Whisky broker Mark Littler believes the collection could go for £40,000, enough for a deposit on a house.

Mr Littler said: “The value of Macallan has risen massively over the last five to 10 years. To have such a vast collection of bottles is the real selling point of these.”
