The expansion works include the addition of fermenters, pot-stills and infrastructure, and will also see a new heat-recovering system installed which will reduce the Keith distillery’s energy usage and carbon footprint.

The announcement comes as the distillery marks 125 years since it first went into production in 1897. Founded by local businessman and philanthropist, Alexander Edward, Aultmore Distillery produces a single malt whisky sold around the world.

Distillery manager Ross Bremner said: “Aultmore Distillery has a long history and association with quality spirit, and the success of our single malt is a testament to those past and present who have played their part in crafting it.

“As we get started on our exciting expansion plans to increase production, it’s an honour for those of us here today to play an integral part in the future of this beautiful whisky.”

Bacardi’s portfolio of single malt whiskies, which includes Aultmore, Aberfeldy, Royal Brackla, The Deveron and Craigellachie, is particularly popular in Asia, where it has grown 30% over the last five years.

The Scotch whisky distillery has been part of Bacardi for almost 25 years.

Niall Mitchell, Bacardi’s VP for supply chain in Western Europe, Australia and New Zealand, said: “We have an incredibly skilled and innovative team here in Scotland and we are so proud of the success of the whisky portfolio we produce.

“As more and more people around the world discover and fall in love with these drinks, we are investing in their growth for the long-term.”
