Origin and Geneology of the Golden Star Hop
Golden Star is the offspring of Saaz and White Vine-OP conceived through open pollination. It was selected by Dr. Y. Mori from the Sapporo Brewery some time in the late 1960’s. Some places mention this hop is the same as Sunbeam, but this has not yet been confirmed.
Flavor & Aroma Profile of Golden Star Hops
Golden Star is an aroma hop that is typically used in only late boil additions, including dry hopping.
Golden Star is grown commercially only in Japan as an aroma hop. It is very difficult to pick and shatters easily, particularly when grown seeded.
Brewing Values for Golden Star Hops
These are the common ranges that we've seen with Golden Star 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 » | 5.4%5.4% avg |
|---|---|
| Beta Acid %Beta acids are a component of hop resins responsible for contributing volatile aromatic and flavor properties. Beta acids contribute no bitterness. | 4.6%4.6% 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. | 36% (Fair) 0.36 |
| 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 » | 50%50% 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 » | 0.63 mL0.6mL avg |

Golden Star Hop Substitutions
If the Golden Star hop is hard to find or if you are simply out of it on brew day, you can try to substitute it with a similar hop. The old way of choosing replacement hops was done by experience and "feel". There is nothing wrong with that way. However, we wanted to build a data-driven tool to find your Golden Star substitutions.
Experienced brewers have chosen the following hop varieties as substitutions of Golden Star:
Is Golden Star available in lupulin powder?
Unfortunately, there is no lupulin powder version of the Golden Star 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.
