Which of the following is a trait of a Munich Helles?

A Munich Helles is characterized by its light color and mild malt flavor. This style of beer, originating from Munich, Germany, is a pale lager that balances a soft malt sweetness with subtle floral hop bitterness. The malt profile is generally smooth and bready, contributing to a clean and refreshing taste that is not overly bitter.

The other choices describe attributes commonly associated with different beer styles. High bitterness and strong hop aroma are more characteristic of American IPAs or other hoppy styles, while strong fruity esters with high carbonation align more with certain Belgian ales. Dark colors and roasted flavors are indicative of styles like stouts or porters, which bear little resemblance to the Munich Helles style. Thus, the correct choice highlights the defining aspects of this particular lager.
