Erdinger is definitely my favorite beer from Germany! Especially when its on draft. And I agree, the alcohol free one, is the best alcohol free beer I know of. I count myself lucky not living far away from the German border since the price in Germany differs a lot from The Netherlands. In Germany you pay less than a dollar for a bottle in The Netherlands it's about 1,5 or sometimes 2.
Enjoy your Erdinger!
Cheers,
Thijs
