I wrote about the beer, after the previous cruise, which we undertook last September, although I don't recall seeing a draft version, back then.
For the beer geeks amongst you, Cunard Black is an oatmeal stout, brewed by Wiltshire brewer, Dark Revolution, to a strength of 5.7%, and is stated to include, coffee, almonds and vanilla in the mix.
The beer is available at various locations around the ship, as well as the aforementioned Golden Lion. The hand-pulled version may well be cask, and I intend to write some more about this' later on, but my favourite spot was the Terrace Bar, at the stern end of Deck 8, overlooking the swimming pool.
As in the photo, Cunard Black is only available in cans, away from the pub. It might be heresy for a former CAMRA member to say so, but I actually preferred the can version to the cask, especially as the former was invariably served, slightly chilled. The beer is definitely well worth checking out, in the unlikely event you encounter any of it ashore, but you never know!
