OTHER INFORMATION: Major export hop for Czechoslovakia; well regarded on world hop markets and traded at very high prices, probably related to availability. Imported to the United States for production of super premium beers; probably identical to USDA 21525 and other Saazer clones that are grown commercially in Czechoslovakia, such as Aromat, Sirem, Lucan, Blato, Zlatan, and others. A heat-treated clone (USDA 21538) is grown commercially in northern Idaho.
