just pulled a pint of what was 2nd best brew to date [ 1st being thirst gold ,top recipee cheers wez] only to find orrible vinegary taste in it , ive had this in barrell for about a month now lovely brew with target and brambling cross hops , been 10 days since i last sampled it and it tastes bad, cant understand why though, carbonations still ok just wondered if recent hot weather could be owt to do with it [barrells are stored in garage] like a tw*t been rationing miself with it with hindsight i should ave caned it, puzzled as to why something thats airtight can go bad :cry:
