Caledonian Brewery's flagship beer Deuchars IPA is celebrating its 25th anniversary and the occasion is being marked with a new brew.

The limited edition Deuchars Imperial IPA, 5.5 per cent, has been created at Wee George, Caledonian's pilot brewery, and will be available throughout October. It was made in collaboration with beer writer and historian Ron Pattinson after researching how IPAs would have tasted more than 100 years ago. 

Also new from the brewery is Dark Light, a 4.7 per cent black lager.

Last week we visited the Edinburgh site to see how it has evolved over the last 150 years
