The lambic's flavour/aroma is a result of a unique fermentation process involving a host of yeasts and bacteria, I recommend J.X. Guinard's Lambic book for more info. It is unfortunate that articles in Zymurgy wriiten by CP lead people to beleive that sour mashing is a part of lambic, perhaps he could read Guinards book after all isn't he the publisher!
