Vienna Lager is known for which of the following characteristics?

Vienna Lager is recognized for its lower alcohol by volume (ABV) and a malt character that includes a gentle toastiness, which contributes to its overall flavor profile. This style typically features a moderate malt sweetness, allowing the malt to shine through without being overly heavy or intense, which is why it is described as having a light toast malt character.

The combination of pale and a small amount of Munich malt gives Vienna Lager its signature toasty flavor without pushing into more pronounced caramel or roasted notes that would come from darker malts. The lower ABV also aligns with the style's refreshing qualities, making it a pleasant choice for many beer drinkers.

In contrast, the other options describe attributes that are not characteristic of Vienna Lager. High bitterness and dark color, claims of being exclusively made with dark malts, or a very hoppy and fruity flavor profile do not contribute to the defining qualities of this style. This makes the identification of lower ABV with a light toast malt character completely aligned with the traditional characteristics of Vienna Lager.
