Which style of beer typically has the highest IBU value?

German Pilsner typically has the highest IBU (International Bitterness Units) values among the choices. This style of beer is characterized by its pronounced hop bitterness, which is a fundamental aspect of its flavor profile. A German Pilsner usually ranges from around 30 to 50 IBUs, enabling it to deliver a crisp, refreshing character alongside a balanced malt backbone.

The other styles mentioned—Oktoberfest, Bohemian Pilsner, and Munich Dunkel—generally feature lower IBU values. Oktoberfest, for instance, is a malt-forward style with a more subdued hop presence, resulting in a lower bitterness. Bohemian Pilsner has a bit higher bitterness compared to Oktoberfest but still does not reach the typical range of a German Pilsner. Munich Dunkel is a dark lager focusing on malt richness and sweetness, leading to an even milder hop character and consequently lower IBU scores. Thus, the German Pilsner stands out for its higher bitterness among these styles.
