Analyses of essential oil from 16 samples and α‐acids and β‐acids in 9 samples of Tettnanger hops grown in the USA showed that they were not the same as Tettnanger hops grown in the Tettnang district of Germany. The composition of the essential oils and ratios of α‐acid to β‐acid in samples grown in the USA were consistent with them being the English variety Fuggle. Samples of USA clones of Tettnanger and Hallertau mittelfrüher grown in Australia also appeared to be Fuggle but a commercial sample of Saaz grown in Yakima was similar to Saaz grown in England, at Wye. The varieties Saaz and Tettnanger were indistinguishable by chemical methods .
