This one of the biggest problems I admit: it seems the choice of cask for many pubs who want a token real ale or are fledgling to the cask scene.Lol.
Cumberland is one of my favourite beers lol
* not many places look after it properly and that's one of its biggest problems
So, often it tastes like vinegar mixed with syrup and gives you the bloody trots the next day, hence why I now religiously keep well away from it.
As a brewer perhaps they should be more cautious of whom they're selling it too as it's getting a bad reputation, but a sale is a sale I guess.
