Astar – Scots Gaelic for ‘journey’ – is matured entirely in ‘bespoke’ oak casks sourced from slow-growing trees on north-facing slopes in the Ozark mountains of Missouri.

Originally launched in 2008 and discontinued about four years later, the NAS (no age statement) expression is described by Glenmorangie director of distilling, whisky creation and whisky stocks Dr Bill Lumsden as ‘like Glenmorangie Original on steroids’.

Glenmorangie Astar owes its character to the use of first-fill American oak casks, chosen for the wood’s porous structure (eight to 12 growth rings per inch).

Seasoned for two years and lightly toasted, heavily charred and seasoned with Bourbon for a further four years, the casks were then shipped to Scotland and filled with Glenmorangie spirit.

The initial Astar expression was discontinued in 2012 because of the expense of sourcing the casks but, since the acquisition of Glenmorangie by French luxury goods group LVMH, Dr Lumsden has invested in four times the number of casks.

He said: ‘I’m starting to get much more volume of this coming through; I think it’s important to maintain quality,’ adding that the reborn Astar was ‘a limited expression, and we’ll see how it goes with people’.

The new Astar is non-chill-filtered and bottled at 52.5% abv – compared to the previous bottling’s 57.1%. Available in the UK from September and other global markets shortly afterwards, it is priced at £74 for a 70cl bottle.

The launch comes as the distillery prepares the second release in its Bond House No 1 series of vintage expressions (replacing the discontinued 25-year-old) – a 1989 vintage single malt following the release of Glenmorangie Grand Vintage Malt 1990 earlier this year.

Glenmorangie is also shortly to announce the latest part of its ‘Beyond the Cask’ initiative, designed to find new uses for old Glenmorangie casks, following the creation of designer wooden sunglasses in 2016.
