The 8.5 per cent ale took silver in the Barley Wine and Strong Old Ales category of the Champion Winter Beer of Britain event, held in Derby this week.
Organised by the Campaign for Real Ale (CAMRA), the competition is the highlight of the National Winter Beers Festival, which runs between 17 and 20 February.
A panel of beer writers, members of the licensed trade and CAMRA members judged this year’s competition.
Norman Sinclair, managing director of Sinclair Breweries Ltd, said: “Skull Splitter has been around for a while now, but it remains one of the most popular ales in our range and is enjoyed the world over by discerning drinkers. Although it has collected many awards over the years, we’re always thrilled when it takes home another accolade, particularly one as prestigious as this. It’s such an iconic ale, one that reflects the history of our islands and our community’s ongoing quest to produce the very highest quality food and drink.”
