OTHER INFORMATION: This hop together with its sister selections Ahil (USDA 21050), Atlas (USDA 21052), and a related selection, Aurora (USDA 21053), entered the hop trade in the 1970's as Superstyrian hops. The implication was that they be similar to Styrian (Fuggle-type) hops but higher in alpha acids content. In reality they are Brewer's Gold seedlings, and their quality characteristics are different from the true Styrian (USDA 21049, Savinski Golding). This has caused considerable confusion in the world hop trade. In recent years the acreage of Superstyrians has been reduced in favor of the old established Savinski (Styrian) Golding (USDA 21049). The acreage of Apolon in Slovenia has remained very limited.
