The George Inn pub in Tunbridge Wells will host the event on 10 December with around 30 sloe gin makers from around the world competing for the title of Sloe Ginster World Champion 2014.
Sloe gin is a red liqueur flavoured with sloe (blackthorn) and drupes (a smaller relative of the plum) and has an alcohol content of between 15% and 30%.
It is traditionally made by infusing gin with bitter tasting drupes using sugar. The sugar is also used to extract the sloe juices from the fruit.
The George Inn, which is a freehold, was chosen to host the event due to its history with the competition as it started as an event for regulars at the Inn six years ago but has expanded since.
Customers of the George Inn come and sample the various sloe gins for a charitable donation.
George Inn publican, Greg Elliot, said: "The whole thing has got a bit out of hand really. It started when a few locals began arguing as to how to make the best Sloe Gin and it ended with 'drink off’ one lunchtime.
"It since turned into an annual event and snowballed from there. It's a nice prelude to the festive season and raises good money for charity."
