The Wern Fawr's regular cask beers are from the 9Lives Brewery (previously Bryncelyn Brewery which started in the cellar of the pub in 1999). There are three regular beers (9Lives) all retaining Buddy Holly themed names, plus one changing guest ale. The bar is home to a large collection of artefacts from the locality and is firmly on the must visit list for real ale and historic pub enthusiasts.
