Weltenburger Kloster Abbey Brewery is the oldest monastery brewery in the world (1050), and its beer has been imported to the US for many years. Up to now, however, all I have ever found in the US is the darker variety. Last week, however, I picked up a 4-can pack of helles at Total Wines and More. It is 4.9% alcohol content, and I liked it, but to be honest, I preferred the darker variety. I have never been there, but it is considered well worth a visit if you are in the area.
There is a note at the bottom of the can that it was "brewed according to the original recipe by the Bischofshof in Regensburg". The abbey itself is located near Regensburg on the Danube.
