Glen Flagler was located in Airdrie, North Lanarkshire, making it closer to being a distillery to England. The distillery was also close to Lilly Loch, which was their main source of water.
Their story begins within the Moffat grain distillery complex. Two sets of stills were constructed in order to supply three single malts, namely Glen Flagler, Islebrae and Killyloch, with a grain Whisky called Garnheath.
Killyloch's stills were taken out of commission in 1970, but Glen Flagler and Garnheath continued production for another decade. The maltings were sold in 1978, and Glen Flagler was demolished in 1985.
The grain plant was also demolished in 1988, for good.
The spirit stills of Glen Flagler were onion-shaped, and had broad short necks. The distillery also had the biggest mash tun in Scotland, made of stainless steel. The complex had 32 warehouses, that could store 500,000 barrels.
