Opal Hops is another product of the Hops Research Center in Hull, Germany. It was bred around the turn of the 2nd century, and is somewhat an evasive hop variety in that it is not that easy to find.
Opal Hops is a dual use hops with moderate alpha acid content at 13.0%-14.0%. Of the oils the myrcene oil content stands out the most.

It is very much German and can be applied anywhere throughout the brew process in beer styles such as Pilsners, Hefewizens, Hells, Lagers, and more
