The Bitburger brewery (in Bitburg, Germany) is a very popular German import in the US. You can usually find it on draft in local German restaurants, as well as in bottles or cans in stores like Total Wines and More. I have had good success taste-wise from canned and bottled Bitburger.
Currently, there is Bitburger Festbier available, and it is very good. Does it taste better in Bitburg? Probably so, but I recall drinking Bitburger in other parts of Germany and being less than thrilled.
As always, I am writing this from the perspective of one who hasn't been back to Germany since 2013 and time can dull your judgment as to what is authentic tasting German beer. Recently, I was able to get my authentic fix at Las Vegas' Hofbrauhaus.
At any rate, the Bitburger Festbier in bottles is 6.2% alcohol, which is just about the way I like it.
According to their website, Bitburger Festbier is available in the US for a limited time beginning in August. Bitburg's annual beer fest takes place in the spring (circa April) and goes for about 3 weeks.
