The rarest bottles of collectible Scotch whisky have grown in value by 13% in the past 12 months.
That's according to whisky index Rare Whisky 101.
The company tracks the auction value of 100 "iconic collectors' bottles" of Scotch, including Macallan, Ardbeg and Laphroaig - among the peatiest of all Scotch whiskies.
Yet it is bottles of Brora and Dalmore whiskies that have shown the greatest increase in value over recent years, according to Rare Whisky 101.
Between 2008 and today, bottles from both distilleries have increased in value by close to 100%.
The Brora distillery stopped making whisky in 1983, although it still releases bottles in small numbers. Which means bottles of its famously peaty drop are hard to come by today. Bottles of its 35-year-old - brought out in 2013 - sell for around £850 ($1,285).
Dalmore whisky, which has been going since 1839, is famed for its complex taste and its small production numbers - a mix that gets collectors excited.
Port Ellen, Mortlach and Bowmore round out the top five whisky investments.

"Buying a bottle of whisky to enjoy on special occasions while putting aside another in the hope it might rise in value over the years is a good way to start," Sukhinder Singh, director of The Whisky Exchange, told This is Money recently.
