Zenith hops were created at England’s Wye College in the 1970s, originating from a seedling selection of a cross. Eventually commercially released in 1987, this high alpha hop is known for its disease resistance.
With a primarily bittering profile, Zenith hops do not contribute significantly to the flavor and aroma of the beer. However, they provide a pleasant bouquet of aromas and hoppy citrus flavors. High alpha and myrcene content, low cohumulone levels, and a myrcene/humulene ratio of about 2:1, make Zenith an interesting dual-purpose hop.
Zenith hops are a great addition to various beer styles like India Pale Ales, Pale Ales, and Stouts. Possible substitutes for this hop include Northern Brewer, Target, and Yeoman.

Zenith Hop Oil Breakdown
Hop oils can vary from year to year and farm to farm but based on our research, here are the typical values we have seen reported. This information comes from various hop farms, The Hop Aroma Compendium, and For The Love Of Hops.
| Alpha Acid % (AA) Alpha acids are what is isomerized when boiling to create bitterness in beer. | 9% – 11% |
| Beta Acid % Beta acids are what give hops their more aroma and flavor compounds. | 3% |
| Alpha-Beta Ratio This ratio of alpha acids to beta acids determines how quickly bitterness fades during aging. Lower ratios are common for aromatic varieties. | INF:1 – 4:1 |
| Co-Humulone as a % of Alpha Higher numbers are said to impart a harsher bitterness. | 25% |
| Total Oils (mL/100g) With more total oils, typically comes a more complex hop profile but these are highly volatile compounds. | 1.76mL |
| Myrcene green, resinous | 52% |
| Humulene woody, piney | 18% |
| Caryophyllene woody | 7% |
| Farnesene floral | 0% – 1% |
| Other Oils: Includes beta-ionine, beta-pinene, limonene, linalool, geranoil & selinene | 19% – 25% |
| Hop Storage Index (HSI) The HSI indicates the percent of alpha and beta acids lost after 6 months of storage at room temperature (68°F or 20°C). | Retains 82% alpha acid after 6 months storage at 20ºC (68ºF). |
| Hop Storage Index (HSI) Rating | Great |
Zenith Hop Substitutions
Replacing one hop for another is seldom straightforward but sometimes you don’t have the right hop or the right quantity of hops for the beer you want to make. For those situations, we have made a comprehensive list of hops to substitute on brew day.
These substitutions aren’t perfect as hop chemistry is pretty complex.
We wanted to make this list of substitutions with varietals that are easy to find when possible. For Zenith, we recommend substituting with the following hops:
Beer Styles
For the most part, any hop could have a place in just about any beer style. Based on popular beers, historical usage, and our own preferences, we would recommend using Zenith for IPA, New England IPA, Pale Ale, Wheat Beer, Golden Ale. That being said, experiment and see what works best for you.
