What type of scent can be classified as 'perfumey' in terms of hops?

The classification of 'perfumey' in terms of hops pertains to specific aromatic qualities that are often sought after in certain beer styles. This descriptor typically refers to scents that are floral, fragrant, and complex, evoking a sense of perfume-like qualities.

Light and aromatic hops, often derived from varietals that feature floral or citrus characteristics, contribute to this 'perfumey' aroma. These hops can impart smells reminiscent of blossoms, herbs, and other delicate, fragrant elements, which align closely with what one would associate with a perfume.

In contrast, the other scent descriptions do not align with the notion of being 'perfumey.' Heavy and bitter hops primarily emphasize strength and a more aggressive bitterness rather than aromatic finesse. Rich and smoky aromas would lean towards deeper, roasted characteristics often found in darker beers but do not convey that light, floral aspect. Earthy and grassy notes tend to relate more to the raw, natural scents found in some hop varieties, which do not exhibit the complexity or delicacy associated with a 'perfumey' scent. Thus, the correct identification of 'light and aromatic' captures those delicate, floral characteristics that align seamlessly with the concept of perfume-like qualities in hops.
