Sour Beers for the beginner What sour beers would be a good starting point for someone that enjoys pale ales and too strong of a flavor profile may turn them off at first?
I'd start an introduction to sour, or wild ales  with the more approachable Lambics, like Lindemans Framboise Lambic.  With a beer like that, the sour notes from the wild yeast are offset by the sweetness of the fruit and the pleasant texture from the fizz of the carbonation, making it an approachable drink not only for one not used to sour ales, but for one not used to beer at all.  

Another option (for a North American) might be a beer categorized as an American Wild Ale, such as Russian River's Consecration, or Sierra Nevada Brux which will have the sour character but also be conscientious of the flavors favorable to the American palate.
