This 15 year old was the inaugural distillery bottling, first appearing in the 1980s. This is the revamped version, introduced in 1993 as part of the Heritage Collection, which also launched new brands for Glen Keith, Benriach and Strathisla. This followed similar packages from United Distillers called the Classic Malts in 1988, and the Caledonian Malts from Allied Distillers in 1991 as the historic blending powerhouses of Scotland slowly adapted to the newly buoyant single malt market at the time.

The age statement was replaced by a 16 year old expression in 2007.

Longmorn is a popular Speyside distillery, and an essential component in many blends over the years. As such, much of its production is reserved for this purpose and although distillery bottlings first appeared in the 1980s, it was rarely seen before the 15 year old expression was relaunched in 1993. The distillery has long been prominent on the independent scene however, and has cult following in Japan, perhaps in no small part to its connection with Nikka founder Masataka Taketsuru, who modelled the stills at Yoichi on those at Longmorn.
