Back in May 1994, the then chancellor made the trip to Glenfarclas distillery to fill and lay a cask in the production site's warehouse vowing to only return to open it when the local constituency voted in a Conservative MP.
In the period since the area had remained an SNP stronghold, that was until 2017 when Douglas Ross won back the seat for the Tories.
This year, Mr Clarke was invited back by Mr Ross to finally open the cask.
Reportedly set to be dubbed the "Chancellor's Cask", it will be bottled with all proceeds going to a charity of Mr Clarke's choice.
The MP for Rushcliffe, who admitted he had long-forgotten about the promise, said he learned a lot about the Scotch Whisky industry on the original trip.
He told Sky News: "Every budget I gave after that, the glass of whisky which I used to make a bit of a prop of when I delivered my budget was Glenfarclas whisky - as I'd so enjoyed my visit here."
Glenfarclas is a family run whisky distillery which was founded near Aberlour in 1836.
