The first person to spot our Sherlock in the participating pubs during the Ale Trail and say to him "You are Sherlock searching for a pint of the unusual and I claim my bottle of beer" will recieve a voucher to swap (over the bar at our pub of the year, The Ship and Castle, Aberystwyth) for a bottle of bottle conditioned Corvedale Brewery's Green Hop and a Wye Valley bar towel.  Ten prizes are available over the festival so keep your eyes peeled.
