The specific flavor of beer is endowed by the diversity of hop varieties and their formula. Most domestic breweries are confined to traditional recipes based on Qingdao hops and SA-1 hops, which leads to serious homogeneity in taste. Nowadays, craft beer is booming in China. In order to provide more choice to beer consumers, new hops varieties are required. New Zealand is another new hops varieties production region except Germany and America. In this paper, the origin and agricultural information of New Zealand hops varieties, the aroma and the brewing properties of known hops, and the application of New Zealand hops were reviewed. Then the bitterness compositions were analyzed by HPLC and hops oil was measured by GC-FID. And the basic flavoring characteristics of hops were determined by tasting. Finally, three hops varieties with special features were used in beer-making test. This study provided more choices for beer brewing in practice.
