Two rare bottles of 33-year-old Ardbeg could fetch between £10,000 and £12,000. Bottled at cask strength and packaged in hand blown bottles with sterling silver labels, the Double Barrel bottlings are a limited edition release by the distillery.
Also featuring will be a 40- year-old Bowmore, with a price tag of between £3000 and £4000. The rare dram was bottled in 1955 and is one of only 306 in existence.
Commenting on the sale tomorrow, McTear's whisky specialist Stephen McGinty, said: "The number of quality bottles coming into the auction house has grown over the past few years and this has led to collectors from as far afield as the United States, China and Australia looking to McTear's to secure some of the rarest drams in the world.
"There is no doubt that whisky continues to hold its own as a long term investment opportunity with good examples of the big five distilleries - Macallan, Bowmore, Highland Park, Springbank and Ardbeg - frequently outstripping more traditional investments.
"In our last sale a 1957 Bowmore made £2200 - 37.5% over our higher estimate - whilst a 25-year-old Macallan sold for £1000 - 20% over the guide price."
Other lots include a rare Port Ellen 12-year-old, bottled to commemorate the visit of the Queen to the distillery in 1980. The bottle has an estimate of between £4500 and £5500.
