Was just reading this on the internet and was curious how yeast affect the flavor of Citra additions.


Citra hops contain higher concentrations of two essential oils (geraniol and linalool) than hops like Cascade, Centennial, and Chinook. Yeast activity converts geraniol into citronellol, which along with linalool is a key component of the characteristic flavor that Citra imparts. Leaving the chemistry behind, Citra produces a different aromatic quality with more tropical/melon notes compared to the classic orange/grapefruit flavor of most Pacific Northwest varieties.

I don't know the extraction temperature of geraniol. But could the presence of yeast during the dry-hopping of Citra affect the flavor of this hop?
