Compass Box first used French oak as inner stave inserts within their casks to age a portion of Highland malt whiskies for a period of secondary maturation, giving the whiskies a rich deep spice character creating The Spice Tree.
However, shortly after it was released it, the Scotch Whisky Association decided that it was illegal as it was a non-traditional production technique and only traditional techniques can be used to call it Scotch whisky. As a result the bottling had to be withdrawn
It was a blended malt which was finished in casks that had extra staves added inside the finishing casks thereby enhancing it with a more spicy flavour. It consisted of 60% Clynelish, 20% Dailuaine and 20% Teaninich whiskeys and was bottled at 46%.
