Was just reading this on the internet and was curious how yeast affect the flavor of Citra additions.
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?
http://www.themadfermentationist.com/2013/02/caramunich-isnt-caramelize-munich-and-9.htmlCitra 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.
