I'm going to flat out say that virtually no craft beer is pasteurized!
It entails extra equipment, money and time and between you me and the tree - most craft breweries just can't afford any of those.
Not to mention the fact that since most craftbrewers have approached the field from the idea of making a more natural and "crafty" product, they take it as a point of pride to not pasteurize. Hell, think of the number of them who proudly state that they don't filter their beer.
