Origin and Geneology of the Admiral Hop

English hops begin to be harvested annually in the fall starting at the beginning of September, and often continuing into early October.
Flavor & Aroma Profile of Admiral Hops
Admiral is a bittering hop that is commonly used only to bitter the beer during brewing, and not for too much flavor and aromas.
Admiral hops have aroma descriptors that include pleasant, resinous hop aroma with hints of citrus (orange) and herbal flavors. Its mild aroma characteristics make it suitable for late-hopping and dry hopping applications in combination with other varieties.

Brewing Values for Admiral Hops
These are the common ranges that we've seen with Admiral hops over the years. Each year's crop can yield hops that have slightly different qualities, so these number ranges are based on history.
| Alpha Acid % (AA) Alpha acids are the main source of bitterness in beer. Longer boil times will result in isomerization of more alpha acids leading to increased bitterness. Learn more » | 13-16.2%14.6% avg |
|---|---|
| Beta Acid %Beta acids are a component of hop resins responsible for contributing volatile aromatic and flavor properties. Beta acids contribute no bitterness. | 4.8-6.1%5.5% avg |
| Alpha-Beta RatioThe ratio of alpha to beta acids dictates the degree to which bitterness fades during aging. 1:1 ratios are common in aroma varieties. | 2:1 - 3:13:1 avg |
| 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). The freshest hops will always be the best. | 85% (Poor) 0.85 |
| Co-Humulone as % of AlphaLow cohumulone hops may impart a smoother bitterness when added to the boil as opposed to higher ones that add a sharper bitterness to the final beer. Learn more » | 37-45%41% avg |
| Total Oils (mL/100g)These highly volatile, not very soluble oils are easily boiled off, but add flavor and aroma to the finished beer when added very late in the boil or during fermentation. Learn more » | 1-1.7 mL1.4mL avg |

Is Admiral available in lupulin powder?
Unfortunately, there is no lupulin powder version of the Admiral hop. Neither Yakima Chief Hops (Cryo/LupuLN2), Haas (Lupomax) or Hopsteiner have created versions of this hop variety in lupulin powder form yet. Too bad too - it is pure hop lupulin powder, which leads to huge, concentrated flavor when used in the whirlpool or dry hop additions.
