[1][2] The Adelphi Distillery was founded in 1826 by brothers Charles and David Gray.
It was sited just south of the Victoria Bridge, at the edge of the Gorbals area of Glasgow.
The Walkers invested in the distillery and added a Coffey still with which to distil grain spirit.
The distillery had an output of 516,000 imperial gallons (2,350,000 L) of pure alcohol per year.
[3] The great-grandson of one of the distillery's founders, Jamie Walker, established the modern day Adelphi independent bottler in 1993, selling the company to Keith Falconer and Donald Houston in 2004.
