Keighley brewery Old Bear has created a star-studded beer to raise money for the National Autistic Society.

The brew, Messier 81, makes its debut from today until Saturday at the Leeds CAMRA Beer Festival.

It will then go on sale in bottles, either from Horsforth Beer Festival on March 27/28 or direct from Old Bear.

Messier 81 was named by Amy Wiggins, 14, daughter of a CAMRA member, in honour of a bright-shining spiral galaxy in the constellation of Ursa Major.

Leeds CAMRA is raising money for the National Autistic Society at the festival and asked Old Bear to create the beer as part of its fundraising.

The brewery will this week deliver the first 18 gallons of the ale to the festival venue, Pudsey Civic Centre, where it will be available on draught.

The beer is available from the brewery by contacting 01535 601222 or oldbearbrewery.co.uk.
