What primary flavor note distinguishes a Vienna lager from other lagers?

Vienna lager is primarily distinguished by its toasty malt character, which often evokes flavors reminiscent of toasted bread. This flavor base originates from the use of Vienna malt or similar malts that are kilned at moderate temperatures, resulting in a mild caramelization that imparts a warm, biscuity, or bread-like note. This toasted bread flavor is essential to the style and differentiates it from other lagers, which may exhibit more pronounced hop bitterness or lighter malt profiles.

In contrast, other options present flavor profiles not typical of Vienna lagers. Roasted flavors are more characteristic of darker beer styles like stouts or porters. Fruity notes can occasionally be found in lagers, but they are more prevalent in specific yeast strains or other beer styles. Citrus flavors are generally associated with hop character rather than the malt-forward profile of a Vienna lager. Thus, the toasted bread note is a defining feature of Vienna lagers, setting them apart within the lager category.
