Meanwhile....

A cold one was waiting for me in the pub close to paradise.

No.
It isn't Guinness.
It is an Archer's Dark Mild, a 3.5% Porter beer which relies on burnt malt flavour rather than alcoholic strength.
An ideal sipping beer on an Autumn afternoon miles from home base.

Of course, Guinness was copied from traditional English Porter-type beers by the Irish and always brewed in London until last year, when the West Acton brewery was closed in favour of concentrating in Dublin alone.

But Guinness, though tolerable sometimes, is merely a beer done in the style of porters.
