Augustinerbrau Helles vs. Hadeer Pschorr Brauhaus Helles

I have had the AugustinerBrau Helles several times since coming here to Munich, and I must say that overall it is very good. I have had it both as a draft beer and in a bottle but I will be describing my tasting from a bottle in my hotel room with no extraneous smells and without anything to eat. This bottom-fermented light lager is very light and clear in color. My guess would be a 4 SRM. You can smell the hops in it, but it is not overly hoppy and is complemented by a slight malt aroma. It is highly carbonated and before I start describing it's taste, I must warn that I'm not much of a helles fan in general. The first impression is that of saltiness, followed closely by the bitter flavor of the hops that lingers after you swallow. The sweet malty flavor, however, takes the bite out of the hops and there are no noticable off-flavors. Overall it is a very crisp light beer that is highly drinkable.
The Hadeer Pschorr Brauhaus Helles, on the other hand, was not very drinkable. I'm thankfull I had food in front of me to help finish this beer off. I had this bottom-fermented light lager at the brauhaus itself so it came straight from the tap. It was a bit darker than the Augustiner Helles, probably around 6 or 7 SRM. It was not as carbonated, and right away when I smelled it I detected the DMS off-flavor of creamed corn. This is a flavor that I've had difficulty detecting before so I can only imagine how strong it would be for other people. After the first sip I tasted a mixture of creamed corn and malt, then the bitterness afterward. It was not pleasant and I ate more of the meatloaf I ordered than I would have just to wash down the corn taste.
