Glengoyne has launched its oldest whisky offering.

The company, owned by Ian Macleod Distillers, said today (19 April) that its 21 Years Old will join the 10, 12 and 17 Years Olds in its portfolio. The malt will be matured in handpicked first fill European oak sherry casks.

The 21 Years Old will benefit from Ian Macleod's repackaging, introduced across the range late last year. The packaging will include a gold-lined embossed box. The aim is to reflect the premium status of the malt within the core range ensuring it stands out as a superior product to the consumer, the company noted.

The malt will also include an introduction of tasting notes on the bottle and box, as well as a separate tasting notes neck booklet, written by the whiskey makers.

"The 21 Years Old is the pinnacle in the Glengoyne core range," said Ian Macleod's marketing director, Iain Weir. "We individually select the Rolls Royce of casks, to ensure the maximum quality of whisky is created. This excellence is now clearly reflected in the packaging design too, giving customers a much clearer understanding of how much the Glengoyne 21 Years Old has to offer."

In November, the distiller said it was investing around GBP20,000 (US$37,950) on revamping its packaging. The move is part of Ian Macleod's attempts to break into the world's top ten single malts.
