The Amarillo variety was discovered by Virgil Gamache Farms Inc. in one of their hop farms in Washington State and propagated and introduced by them as Amarillo. Unlike most varieties of hops, which may be acquired and propagated by the purchase of rhizomes, Amarillo hops are privately grown only by Virgil Gamache Farms; also the organization holds a trademark on the name "Amarillo" for hops.
The resultant aroma is of medium strength and very distinct, described as flowery, spicy and citrus-like with a distinct orange bouquet.
The hop is good for flavor and aroma but can also be used for bittering effectively because of the low cohumulone content.

The alpha acid content of hops will vary from batch to batch and may vary from the amount shown in the picture.
