Determination of Essential Oil in Hops and Hop Products. Ronald J. Burkhardt, John I. Haas, Inc., P.O. Box 1441, Yakima, WA 98907. J. Am. Soc. Brew. Chem. 44:0038, 1986.

This paper describes a method for the determination of the essential oils of hops and hop products. A modification of the Wright and Connery method using 100 g of ground hops in 3 L of water has been found to give excellent results. Only 4 hr is required to bring about complete distillation of the oil in ground hops and hop products. Such a method may be suitable as a standard method.
