New and existing investment by Levenmouth’s biggest employer is signalling the firm’s faith in Fife.
Diageo last week announced it was pouring over £1 billion into the Scotch whisky industry.
The large-scale venture includes previously-announced plans for a bonded warehouse facility in Kirkcaldy, costing around £150 million.
A bid for planning permission has been lodged with Fife Council which, if approved, could mean jobs at the construction and operational stages of the project, at Begg Farm.
Also included were proposals to build a new distillery in Speyside or the Highlands.
Diageo has also committed around £100 million to upgrading Cameronbridge distillery in Windygates, with increased production and a new bioenergy plant.
The new £86 million bottling plant at Leven has already started production and should be operational later this summer, said a spokesman, while a premium/luxury products area was also due for completion soon.
Diageo had indicated a firm commitment to Scotland and invested heavily in Fife in recent years, added the spokesman.
Chief executive Paul Walsh said the company was very confident about its ability to continue to increase its business because of the growth it was seeing locally in emerging markets.
Diageo’s announcement last week was welcomed by politicians across Fife.
