Sladek - is characteristic by a high share of beta fraction and high yield potential. The variety was registered in 1994. The current acreage is around 200 ha with a production of 400 - 500 t. This variety was a part of a long trial and was tested together with many aroma varieties (Hal. Tradition, Cascade,.) and always won. Sladek is a foremost variety for the second hopping of lager type beers (with Saaz used for the last hop addition). Some breweries use it also for third hop addition in case of non-premium beers. The origin of Sladek is in Saaz aroma hops and therefore the content of beta acids is high and these make the character of bitterness very fine.

Premiant - is characteristic by a higher alpha content and yield potential. Premiant was registered in 1996. The current acreage is around 200 ha with a production of 400 - 500 t. This variety was a part of a long trial. Premiant in its group mostly pushed out other varieties (Perle) and it is used in Czech breweries for the second hop addition. 50 % of its origin is Saaz fine aroma hops and has a low cohumulone content. It has positive effect on fine beer bitterness. According to our experience some breweries prefer to use Sladek and some Premiant - each variety has a unique character. Premiant has a neutral bitterness.

Agnus - is characteristic by a high beta acids content (alpha/beta ratio is approx. 2,0 while most of other high alpha varieties in the world have this ration around 3,0). In genetic origin of Agnus is variety Sladek (therefore a high beta content) and also other good quality characteristics. Agnus is used by large Czech breweries. The brewing quality is comparable with other varieties (Magnum, Taurus, Columbus, Target) however from the brewing results it has a better effect on beer stability. Therefore this variety is used for export beers. The results of research tests show that this variety is suitable for extraction as well as processing into pellets and so not only for first hop addition but also for second hop addition (high beta acid content).

Harmonie - is characteristic by a high share of beta fraction but oppose to Sládek it has higher content of alpha bitter acids. The variety was registered in 2004 and therefore the acreage is currently very limited. The first brewing trials and testing in Czech breweries showed at very good quality especially for intensity and quality of beer aroma.

Rubin is a bitter variety but it is genetically similar to old middle European aroma hops. The Saaz variety evidently influenced its genome. It has fine bitterness with longer dying away in comparison to Saaz.
