What is one of the primary aroma characteristics of a Belgian Dubbel?

The primary aroma characteristic of a Belgian Dubbel is indeed the perfumey and honey-like aroma. This style typically features a rich malty sweetness that is complemented by fruity esters produced during fermentation, such as dark fruit notes (think raisins or figs). The appearance of honey-like notes can also arise from the use of caramel and dark malts, which contribute to the overall perception of sweetness and richness. These characteristics create a complex aroma profile that is signature to Belgian Dubbels.

While other options might touch on aspects of different beer styles or characteristics, they do not encapsulate the hallmark aroma profile associated with Belgian Dubbel. For instance, floral and herbal hops are typically less emphasized in this style, and while low to moderate hop spice and light phenolic notes can be found in some Belgian beers, they are not defining characteristics of a Dubbel. Ultimately, the perfume and honey-like aroma are what truly stand out in this beer style.
