Barley wine - Whitbread sold it as "Gold Label". It used to be in 1/3 pint bottles. Popular with old dears allegedly, who could tolerate two.
The brewery in it's wisdom decided to repackage in half pint cans. Two of those were too much for the usual consumers who could end up falling off their bar stools so sales fell away. Dad (worked for Whitbread) ended up bringing a couple of trays home every few weeks as stock would go out of date. He related the above story to me. I could manage two cans, Mum couldn't
