History and Origin of Amarillo Hops

Amarillo was discovered in 1990 at the Virgil Gamache Farms in Washington state. One of the workers noticed a strange hop plant growing next to a Liberty hop plant. The unknown hop had an unusual appearance that included yellowish bine and immature leaves. While it looked somewhat similar to Liberty hops, it was apparent that the newcomer had a different look.

The farm was curious enough about this new hop plant to leave it alone and allow the cones to develop. The cones it produced were smaller than usual, which further led to their curiosity. Virgil Gamache Farms started cultivating and propagating Amarillo in 1991 and finally started selling it in 2003.
