OTHER INFORMATION: This hop like its sister selection Lubelska is probably a Saazer clone which was brought to Poland from Czechoslovakia, probably before World War I and was given a local name. The trade markets both hops together under the Lubelski name and both have similar brewing performance. There appears to be little difference in yield performance between virus free and virus infected clones.
