For those unfamiliar with this type of beverage, "Milk Stout" is brewed with the addition of lactose (a sugar derived from milk) which is not converted into alcohol during the fermentation process, making the resulting brew both relatively weak and very sweet. It was the brew supposedly favoured by elderly ladies and nursing mothers. It was far too sweet for my palate but made for a passable tipple when mixed with a half of a decent bitter: a sort of Black and Tan. For some years now, apparently, Mackeson has been a 'ghost brand' in the UK: still produced and sold but without advertising or promotion. I'm not sure what the logic behind this is: perhaps the major markets are overseas?
Footnote: I could have called this post "Thoughts occasioned by the finding of an old Mackeson tin in the garden". Little did I know then that, in a split second, my mind would wander from the tin to Ena Sharples and Minnie Caldwell via Bernard Miles. I wonder how many other people remember them?
