Pacific Gem is a New Zealand hops variety of interesting character. Bred at the New Zealand Horticultural Research Centre as a triploid cross between Smooth Cone, California Late Cluster and Fuggle, it is used around the world in various styles but most notably in European lagers. It was released in 1987.
Despite its high alpha acids its high cohumulone content makes its use as a bittering hop problematic. It can, and is, used as an early addition but is more well known for its aroma and flavor. When utilized as a late addition it can bring a delicate aroma character to the resulting beer that is smooth and oak-like with notes of blackberry.
A triploid alpha type developed through the New Zealand Hop breeding program, Pacific Gem fills the brew house with enticing aromas during kettle addition and has been described as producing oaken flavors with a distinct blackberry aroma. It is typically used as a first hop addition and makes its presence felt through an excellent tempered bitterness and flavor while later additions deliver citrus and pine aroma notes. Pacific Gem is a good all purpose hop that delivers quality bitterness along with flavor and aromas. It is excellent in international lagers and can also be used in IPA’s and other big styles.
Aroma: Specific aroma descriptors include spicy black pepper and berry fruit aroma characteristics; some brewers have noted delicate blackberry, floral or oak tones.
