Defender

Defender has an interesting heritage. Bred from a New Mexico Wild American female, Eastwell Golding and other English hops it was selected in the early 1960’s by Dr R. A. Neve at Wye College in England. Despite its significant humulene and farnesene content, Defender’s very low alpha percentage and low yield potential has significantly hindered its commercial viability. It may show promise in breeding though with a promisingly high alpha to beta ratio. It is said to impart a pleasant, European-style aroma.
