Lovely fruity ale. Lovely malty taste

I never learn do I? Time after time I give a 'fruit' beer a try, and I rarely enjoy it. This is a pale ale infused with blueberries brewed about a mile away from where I'm suppin it. It has cascade hops - which I love - and has a good mouthfeel and consistency down the glass. However, the blueberries give it a little 'sourness' in the initial taste. Of course it may be that the beer is going off, but I would be surprised at that in a busy city centre pub like this.
