Posting this for a few reasons: seems cheap, seems not widely available normally, seems well regarded.
I got this because of an interest in 'smoky' single malts. On first tasting it wasn't vile, so as it may be an acquired taste, I've bought a couple more to mull over today (3rd July).
Researching this as a deal (Googling "buy Okell's Aile UK") I got pretty much nowhere. Very few places sell it. Now being in B&M (and generally these deals are national) its available to pick up and try fairly easily for anyone in striking distance of a B&M store.
Should you try? Well the only hit I got was £2.85 for a 330ml bottle (http://beerdock.co.uk/index.php/breweries/french-beer/pelforth-brewery/okell-s-brewery/okells-aile-330ml-bottle.html) so looking good price wise for this 500ml bottle.
Also if you look at the following page you will see its often an award winner in its class of "smoked beer" (http://www.worldbeerawards.com/best/smoked-beer.html) so it should be a good 'un.
BBE is Nov 2014.
They have a few other Okell's at the same price and size - IPA and Maclir.
Also of note they had (Wigan central store)
Bateman's Bohemian Brew Black Pepper Ale 500ml £1.29. Pepper pouch included.
Marston's Imported Shipyard Blue Fin Stout American Craft Beer. Worth a pop at 79p for a 355ml bottle.
And finally another Craft proclamation in the guise of Revisionist Craft Lager. Got this principally as it is not pasteurised, again 'just to try'. 500ml for £1.19 making it the cheapest of the 500ml's I've mentioned.
