I just brewed my first batch of Hefeweizen last week. I did not listen to the wife and racked it off of the primary fermenter early. In the secondary fermenter the fermentation was vigorous to say the least. It blew the cap off of the air lock. My wife thinks that the beer may have an infection, but I tasted it and it taste fine to me. I think that all it needs is alittle more time in the carboy and it will be fine. I would need some advice.
