On 22nd October I arrived at The Woodman, Ashtead, with a party of eight for lunch.
We ordered a round of drinks, including a pint of Black Wolf Big Red.
After trying it, it was clear that it was no longer drinkable (vinegar notes).
Being the Secretary of my local CAMRA branch, I know what I am talking about.
I took it back and told the barman, who asked whether I would like something else.
I took a pint of Hop Head from Dark Star.
When I got home I was astonished to see that I had been charged £3.70 for the beer I had taken back.
