European beer imports............................pasteurized?

I have successfully grown yeast starters from Unibroue and domestic US bottle conditioned beers but no matter how small the original starter used I cant grow one out of a Belgian/German beer to save my life.

Does anyone know of a state by state list of what the specific laws/regulations are regarding imported beers? (I live in Massachusetts)

I swear that I’m just trying in vain to grow samples from bottles that have been heat pasteurized.
I know for sure the Monks didnt put that label on the Rochefort 8 I drank last night.

I believe all save a few german hefeweizens are pasteurized (I believe Erdinger is on of the few that isn’t) - I have successfully recultured yeast from Delerium Tremens, haven;t tried m uch else since you can get most of those yeasts from WY and WL.

Have you ever tried DT?  Seems like lots of people (including myself) have cultrued that one.

Anyone else in Mass on the forum have the same trouble?

Sorry.  I don’t know of a list.

(major - You beat me too it but I’m posting anyway)

The odd most of the Belgian & French beers reculture fast.
