The appointments coincide with an increase in brewing capacity and a doubling of office and warehousing space at the Alva-based brewery, where Bitter & Twisted, Schiehallion and Ola Dubh are made.
Knowles previously worked with spirits firm Allied Domecq and with Veuve Clicquot, Krug and Lanson Champagnes.
He acknowledged that brewing is new territory for him but he said: “I recognise the same level of craftsmanship, dedication and passion going into Harviestoun’s beers that I have previously experienced working with the world’s top wines. Craft beer’s meteoric rise and continued growth make this the perfect time to work with an internationally acclaimed brewery that has been one of the leaders in innovation and quality for nearly 30 years.”
Ewan comes from a traditional brand and marketing background but for the past five years has specialised in internet marketing and social media.
“I’m thrilled to be on board,” he said. “I remember the first time I tried Bitter & Twisted ten years ago and have been an avid fan of Harviestoun beers ever since. It’s brilliant to be communicating with like-minded enthusiasts and I am particularly excited by the prospect of growing our fanbase over the coming months and years.
“With the craft beer and digital revolutions in full swing, it’s hard to imagine a more exciting business to be part of right now.”
