Scotch whisky producer The Glenrothes is marking the retirement of its malt master with an extension to its portfolio.

The Glenrothes, which is owned by BB&R Spirits, will launch The Glenrothes John Ramsay in September, after Ramsay steps down from his position after 43 years of service to the whisky industry.

The variant will be available at Berry Bros & Rudd and other specialist retailers for around GBP700 per bottle.

"This exceptional bottling is a fitting tribute to one of the quiet men of blending," said Ronnie Cox, The Glenrothes' brands heritage director. "John lets his whiskies do the talking. I am confident The Glenrothes John Ramsay will prove to be an extremely articulate expression that will find favour with whisky enthusiasts everywhere."

The expression has an engraved copper label, while each individually numbered bottle has John Ramsay's signature etched onto it. The oak box features a bottle-shaped window and carries a leather booklet with John's own description of how he crafted the whisky.

The run of The Glenrothes John Ramsay will be limited to 1,400 bottles.
