Analytical values for α‐acid content of twelve varieties of hops from the 1986 crop are presented in relation to the district of production. The variabilities of Wye Northdown, Zenith and Wye Challenger follow similar trends to those of previous years, while Northern Brewer has continued to show a reduction in variability. Following the increase in sampling rate, Yeoman has reverted to an acceptable level of variation. Fuggle, Progress and Bramling Cross have increased their variabilities but remain within acceptable limits. The variabilities of Goldings, W.G.V. and Wye Target, despite the increase in sampling rate of the latter, have attained higher than normal levels. The sampling rates have been considered and in view of the adverse growing conditions encountered with the 1986 crop, no changes have been recommended.
