There are also Export strength Helles, but those are only a little stronger, say 1.056 OG vs 1.048.
And its a far more enjoyable style in my opinion
I believe Munich Helles exists for two reasons. 1. Mandatory liter while visiting Munich. 2. As a challenge for brewers, a style to hone your skills on.
It sells really well in Munich, another reason.
I lean towards the Helles one might find in Bambarg or Regensberg, definitely a hop aroma, some hop flavor. Not a Pils by any means, but more than an inkling of hops.
