from The Century Dictionary and Cyclopedia

  • n. An acrid oil obtained by pressure from the flower-heads of the hop, Humulus Lupulus.


Sorry, no etymologies found.


  • On the other hand, we can allow hop-oil to stand for days without its odor being perceptibly changed; it appears to me more than probable that the peculiar smell of old hops is due far more to the oxidation of the bitter substance than to the oxidation of oil.
