Which of the following is a trait of a Doppelbock?

A Doppelbock is characterized by a high alcohol by volume (ABV) content, typically ranging from 7% to 10%. This strong alcoholic strength provides a warming quality that aligns with the style's origins and the traditional brewing methods used. Originating from Germany, where it was historically brewed as a rich, strong beer for monks to sustain them during fasting periods, the higher ABV is a defining characteristic.

While bready malt flavor may be present in a Doppelbock due to its malt-forward profile, this is not exclusive to this style and is found in many traditional German lagers. The color can range from pale amber to dark brown but is not necessarily black. Additionally, Doppelbocks are known for a rich, malty sweetness rather than pronounced bitterness, which further distinguishes them from other beer styles that may prioritize hop character.

Thus, the key identifying trait that accurately captures the essence of a Doppelbock is its high ABV, distinguishing it from lighter or less intense lagers.
