The North British Distilling Company is a grain whisky distillery located in Edinburgh’ Gorgie district on the south west of the city. The distillery was originally founded by a group of independent distillers in 1885 and the site was selected due to its close proximity to the national railway network which allowed access to deliveries of grain and also easy access to product distribution. It was also close to the Port of Leith allowing for easy deliveries of maize and grain as well as an easy way to export products. The distillery was also positioned near the city sewer which allowed easy and efficient access to the flushing out of effluent. The site is currently owned by Lothian Distillers which is a venture jointly owned by Diageo and the Edrington Group. This was to increase the sales of Scotch whisky to India, China and South America and brought about production of 65,000,000 litres per annum. Mainly used in Johnnie Walker and Famous Grouse production.

This single grain whisky was distilled in 1991 at the North British Distillery before being placed in a refill Sherry Butt and left to mature for no less than 30 years. It was bottled at with natural colour and no chill-filtration in 2020 at 55% ABV as part of the Signatory Vintage Cask Strength Collection. One of only 503 Bottles produced.
