Amarillo hops is one of the happiest accidents ever happened within the beer industry.

We’ll also discuss how Amarillo is used on a personal and commercial level in the hops world. Let’s get brewing!
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.
Amarillo is so-named because of the yellow cones it produces. While Amarillo is considered an aroma hop that’s added in late-boil additions, it has a relatively high alpha acid content. It also has one of the highest Myrcene oil levels of any hop variety. Amarillo is the shortened version of the hops full name, Amarillo VGXP01. Amarillo is patented and owned by Virgil Gamache Farms, and they have sole rights over its growth and distribution.
