New classification of geraniol-rich hops

Geraniol derived from hops | Monoterpene alcohols are regarded as very important factors for the ‘Varietal Aroma’ of hops [1, 2]. Linalool is a monoterpene alcohol contained in all hops. However, geraniol is considered to be more variety-specific than linalool. For example, European traditional hop varieties contain very small amounts of geraniol. US hop varieties often have large amounts [3]. In addition, researchers have reported that geraniol may be contained in hops as free geraniol together with several geraniol precursors.
