Guinness Irish stout has traditionally been paired with oysters since the 18th century. They were particularly popular amongst the working classes, thanks to their low price and prevalence in public houses. However by the 20th century, oyster stocks were in decline and punters tended to favour pale ale, meaning the combination became increasingly rare.
