What is one attribute of dark ales mentioned in the text?

Dark ales are characterized by their strong malt characteristics, which is a defining feature of this style of beer. The malting process, which involves roasting the grains, imparts deeper flavors and colors to the ale, often resulting in notes of caramel, chocolate, or coffee. This robust malt profile is what distinguishes dark ales from other beer types, contributing to their overall taste and body.

The other responses, while they may apply to certain types of beers, do not specifically highlight what makes dark ales unique. For instance, dark ales are often enjoyed at a variety of temperatures, and their body can vary, but it is the strong malt characteristics that are most emblematic of the dark ale style. Additionally, while hops contribute to the flavor of beer, dark ales are not defined by the type of hops used but rather by their malt content.
