The overseas beers on offer at The Henry Bell in James Street have been sourced from brewers in Japan, Lithuania, Holland, Australia, Canada, Italy, USA and Belgium.
The festival will also feature beers from across the UK, including speciality beers (ingredients include heather, grapefruit and elderberries), as well as beers brewed exclusively for the pub.
It will run from Wednesday, October 24 until Sunday, November 11.
Pub manager Phillip Carville said: "We will be serving the largest selection of overseas beers ever available in the pub, together with a fantastic range of UK beers.
"Many of the beers on offer have not been available in the pub beforehand and I am looking forward to serving them.
"The festival promises to be great fun and I am certain that customers at The Henry Bell will enjoy themselves."
