Which Hops Have the Most Geraniol?

Geraniol Hops

Geraniol has a waxy, sweet rose odour and is found in many but not all hops. It’s found in Cascade, Citra, Centennial, Chinook, Pacific Hallertau, Southern Cross, Motueka, Aurora, and Styrian Golding hops. It isn’t found in UK Challenger, U. S. Challenger, Alsace Strisselspalt, Spalt Select, Sterling, Czech Saaz, Millennium, or German Magnum.

It’s also a primary component of the essential oils of roses, palmarosa and citronella, and is found in small quantities in geranium and lemon. It has a rose-like, floral, and citrus fruit aroma and flavor. Geraniol is also found in coriander, lavender, lemon, lime, nutmeg, orange, rose, blueberry, and blackberry. It is commonly used in perfumes and flavours such as peach, raspberry, grapefruit, red apple, plum, lime, orange, lemon, watermelon, pineapple, and blueberry.

Geraniol attracts bees but repels of mosquitoes and is used in many DEET-free repellent preparations. Geraniol is produced by the scent glands of honeybees to mark nectar-bearing flowers and locate the entrances to their hives.

It has low solubility in water, but it is soluble in common organic solvents. When oxidized, geraniol becomes geranial or citral. Geraniol is a byproduct of the metabolism of sorbate and, thus, is a very unpleasant contaminant of wine if bacteria are allowed to grow in it.

Geraniol is a moderate skin irritant and can cause allergies. Exposed to air, its oxidation products are more irritant and allergenic.
