The Duke of Rothesay tries whisky from a keg at Wolfburn Distillery

The Duke of Rothesay today carried out engagements in Caithness, Scotland.

The Duke first visited Scotland's largest offshore wind farm before unveiling a plaque to mark its official opening.

His Royal Highness described the Beatrice Offshore Wind Farm, situated near a former oil field in the Moray Firth, as an "engineering feat".

The Duke met staff and heard about the 84-turbine development, which will be able to power up to 450,000 homes and will generate £2.4 billion to the UK economy over its lifespan, with £1 billion expected to come to Scotland.

Willie Watt, a former Wick harbour chairman and local resident, called the creation of 370 local jobs for the town and 90 for the harbour itself "the best news in 100 years".

He added: "This is a great day after years of difficulty for the town.

"The wind farm has brought a new industry, new jobs and apprenticeships for young people to the area."

His Royal Highness then visited Wolfburn Distillery near Thurso in the Highlands, the most northerly whisky distillery on the Scottish mainland.

The Duke was given a tour of the premises, sampled two of the distillery’s drinks and bottled a specially engraved whisky.

The Duke was given a demonstration of the bottling process before filling his own container with Aurora whisky.

The glass was engraved with HRH The Duke of Rothesay to mark the occasion.

His Royal Highness then met members of the public who were waiting outside the distillery. The Duke spoke to a group who were doing a charity fundraising cycle from nearby John o' Groats to Land's End.

Laura Amber, 27, from Manchester, said: "He was very friendly and very nice.

"We stumbled across the place and wanted to have a little tour but couldn't because there was a special visitor that beat us to it."

Lenore Eng, 54, from Toronto, Canada, said: "I found him incredibly charming, he had incredible eye contact, he was very interested in all of our work - so that was good.

"He had a special little dram and I'm sure we will tonight."
