Black Sheep Brewery has marked the 50th anniversary of Monty Python by releasing a special cask beer named in honour of the comedy legends.

The beer, 'Monty's Python's Flying Circus', is available throughout September and October to coincide with two months of celebrations of five decades of hilarious sketches and cult movie classics.

Brewed using a blend of pale ale malt and crystal rye along with hops of First Gold, Galena and Amarillo, the 4.5 per cent ABV beer has been developed as part of Black Sheep's exclusive brewing collaboration with the Pythons and completes a trio of Black Sheep beers inspired by John, Michael, Eric, Graham and the two Terrys.

And, as this is a very special occasion, Black Sheep is also re-releasing 'Brian', the beer named after the 1979 film, for two months.

The brewery is also helping pubs spark laughter and hilarity by developing a seven-round Python-themed quiz.

Pub goers will also be encouraged to wear Python-themed fancy dress for the quiz nights and send photos to Black Sheep with the best picture winning a unique signed Monty Python plaque.

Rob Theakston, managing director at Black Sheep Brewery, said: "While the parrot may be dead, Monty Python is alive and kicking and it's fantastic to be able to support the 50th anniversary with the release of our commentative 'Flying Circus' beer.

"We're very proud of our long and exclusive relationship with the Pythons and having all three of the beers we developed with them available together for the first time is a great way to mark this momentous occasion."
