A 140-year-old bottle of beer brewed for an arctic expedition is to be auctioned after being found in garage.

The beer – Allsopp’s Arctic Ale – was brewed in Burton-upon-Trent, Staffordshire, for an expedition led by Sir George Nares in 1875.

The unopened bottle was discovered in a box in a garage in Gobowen, Shropshire, but auctioneers said it was a mystery as to how it got there.

The bottle is expected to fetch up to £600 / $950 when it is auctioned on 13 June.
