Millennium hops originated from the John I. Haas breeding program and were released in 2000 as a super-alpha variety. Known to be a descendant of Nugget, the Millennium name was chosen to mark the turn of the Millennium.
Millennium hops offer a unique flavor and aroma profile consisting of citrus, floral, and herbal notes. These are subtly complemented by spicy, woody aspects, such as toffee, yogurt, tobacco, sage, curry, and red berry. Although its primary use is as a bittering hop, Millennium hops also provide a distinct resin, floral, toffee, and pear aroma.
Five beer styles that could benefit from Millennium hops include American Pale Ales, Amber Ales, English IPAs, Stouts, and Barleywines.

Millennium 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. | 14.5% – 16.5% |
| Beta Acid % Beta acids are what give hops their more aroma and flavor compounds. | 4.3% – 5.3% |
| 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. | 2:1 – 4:1 |
| Co-Humulone as a % of Alpha Higher numbers are said to impart a harsher bitterness. | 28% – 32% |
| Total Oils (mL/100g) With more total oils, typically comes a more complex hop profile but these are highly volatile compounds. | 1.8mL – 2.2mL |
| Myrcene green, resinous | 30% – 40% |
| Humulene woody, piney | 23% – 27% |
| Caryophyllene woody | 9% – 12% |
| Farnesene floral | 1% |
| Other Oils: Includes beta-ionine, beta-pinene, limonene, linalool, geranoil & selinene | 9% – 42% |
| 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 76% of its alpha acid after 6 months of storage at 20ºC (68ºF). |
| Hop Storage Index (HSI) Rating | Good |
Millennium 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 Millennium, 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 Millennium for IPA, New England IPA, Pale Ale, Wheat Beer, Golden Ale. That being said, experiment and see what works best for you.
