Got an e-mail from West Mayo Brewery[/url:3n8nhyw3] who have just released their first beer, Clew Bay Sunset red. They're doing kegs and I'll see if I can get a list of current pubs from them.
The pubs they're aiming for are: The Porterhouse (Westport), The Tavern (Murrisk), Bar One and Bosh (Castlebar) and the Halfway House and Key West (Islandeady). Waiting to hear if it's in any of them right now.
