Geraniol Beer Flavour Standard

Geraniol (Geranyl alcohol)

Geraniol is a rose like, floral or rose water flavour that occurs in beers. Imparted to the beer via hops it’s an important character of hop oil (essential oil of Humulus lupulus). It’s concentration is determined by the type of hop, the hopping regime, by wort boiling and fermentation conditions.

Geraniol provides the contribution to the flavour of some beer’s floral character and hop aroma. Being able to detect and understand geraniol helps sensory panellists to determine if their beer matches the correct brand profile.

We recommend that intermediate sensory panellists or those who encounter Geraniol on a regular basis are trained with this flavour.

Our Geraniol Beer Flavour Standards are available in blister packs of 5 capsules.

To train with this flavour swirl your sample glass to release the aroma, take short sniffs while holding the beer to the nose.


This a recommended flavour standard of ASBC and the EBC.
