Glen Flagler

Established in 1965 by Inver House Distillers, a subsidiary of Publicker Industries of Philadelphia, Glen Flagler operated within the expansive Moffat complex in Airdrie. It sat alongside the Garnheath grain distillery. Unusually, its name does not derive from a Scottish glen, but from Flagler Avenue in West Palm Beach, where Publicker chairman Simon Neuman resided. The facility used conventional copper pot stills to produce malt whisky intended primarily for the company's own blends, such as Mac Arthur's and Pinwinnie. The site functioned for only two decades before the industry downturn led to its closure in 1985.

Following its closure, the distilling equipment was removed and the buildings were demolished in 1988. However, the site was not completely abandoned; the warehousing, blending, and bottling facilities were retained to serve as the corporate headquarters for Inver House. Despite its short operational life, Glen Flagler achieved a cult status among collectors due to the scarcity of its single malt bottlings. While the distillery shared a site with grain production, its output was distinct. Today, the only remnants of the Glen Flagler name exist in rare vintage bottles and historical records of the Airdrie industrial distilling era.
