The Freshfield Hotel in Formby has long been noted for serving a good range of real ales. I've just learnt that it's just about to hold a beer festival with 60 beers, including the following breweries:
Allgates, Amber, Black Iris, Blueball, Boggarts, Brampton, Brimstage, Hawkshead, Leeds, Liverpool Organic, Moorhouses, Muirhouse, Mr Grundy's, Peerless, Picktish, Phoenix, Raw, Saltaire, Spitting Feathers, Wapping, White Rose, XT.
That looks like a rather good selection to me. It runs from 21st to 28th January and is at the Freshfield Hotel, Massams Lane, Formby, L37 7BD. Tel: 01704 874871. The pub is less than 10 minutes' walk from Freshfield railway station.
