7% Ave. Alpha. This is a new German hop from the German research center Hull that exhibits excellent aroma characteristics combined with a respectable alpha acid level. Opal is a European jewel which has a sweet spice, slightly peppery aroma and flavor combined with a light clean citrus fruit aroma. We think this hop will do well in German wheat beers, summer ales, Helles, light European lagers, light ales, Saisons, and Belgian wit. A good substitute for East Kent Goldings, Styrian Goldings, or Tettnanger.
