Origin and Geneology of the Stirling Hop
Sterling hop's parentage is readily apparent in this dual-purpose hop variety. Sterling is the daughter of Saaz and Cascade with some open pollination of German varieties.
US hops begin to be harvested in mid-to-late August for most aroma varieties.
Flavor & Aroma Profile of Stirling Hops
Stirling is a dual-purpose hop that can be used in all hop additions throughout the brewing process.
The spicy characteristics of the Saaz play well with the bright citrus from the Cascade. While it is primarily used as an aroma hop, it is versatile enough to work in a wide range of styles and uses.

Brewing Values for Stirling Hops
These are the common ranges that we've seen with Stirling 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 »
|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%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.||1:1 - 3:12:1 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.||70% (Poor) .70|
|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 »||21-28%24.5% 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 »||1.3-1.9 mL1.6mL avg|
|Total Oil Breakdown:|

Stirling Hop Substitutions
If the Stirling 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 Stirling substitutions.
Experienced brewers have chosen the following hop varieties as substitutions of Stirling:
Is Stirling available in lupulin powder?
Unfortunately, there is no lupulin powder version of the Stirling 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.
