Brains latest advertisement campaign claiming to be the number one Welsh Ale. Well on capacity alone Brains can brew more than any other brewer in Wales, apart from the In-bev factory at Magor, but since that's made with toilet water from trains flushing in the Severn Tunnel I don't count that. One thing to notice is the brand of ale is not mentioned but 'Smooth' and 'Cold' are? So which Brains brand is the number one in Wales? Could hazard a guess at SA but some figures to back up the claims would be useful.
