Brewdog has unveiled plans to create a new brewery and visitor centre in the North-east.
The craft beer firm wants to create the facility in Ellon beside its headquarters at Balmacassie Commercial Park.
The firm employs almost 300 people at the base in the town and more than 540 worldwide.
If approved, the plans would see a sour beer brewery, production offices, a visitor centre/gallery and a car park built on land next to Balmacassie Way.
The company was founded in Fraserburgh in 2007 by James Watt and Martin Dickie before moving to Ellon.
A statement sent to Aberdeenshire Council planners on behalf of BrewDog says: “The benefits of the state-of-the-art production facility are only now being realised and projections show that the demand is not waning by any means.
“The level of employment at the campus is now nearing 300 people – which does not take into account the bar divisions located across the UK and worldwide.”
It adds: “Staff and visitors alike will not be able to enter the existing brewery facility after experiencing the sour environment, so as to avoid the risk of cross contamination.
“It is anticipated that a team of around four people will operate the stand alone facility and associated laboratories.
“The proposals allow the unprecedented success of a local based business to further reinforce their identity in the Ellon locality providing further employment opportunities as well as drawing high levels of visitors for the tours and the like – boosting the local economy as a whole.”
Aberdeenshire Council has already agreed to move its recycling facility in the town to make way for future expansion.
The brewery has also been given the option of acquiring an adjacent council “waste bulking facility” site.
