Lisa don't fret - The new German beers are much better and more authentic than Becks. If your DH truly likes beer he should love the new additions to Germany. Anyway, he can get Becks just about anywhere (grocery stores, bars, 7-11) so I think the new German beers should be more special.
I was actually extremely happy they replaced Becks for some "real" German beer. I have been to Germany a few times and never even saw Becks there.
Either way - have a great time!!
