Aurora is a fantastic hop with a rich bloodline produces a fair-sized amount of flowers on a single thick vine. It is a dual-purpose hop that is easy to harvest because they don’t rip easily and handle well.
This Slovenian hop isn’t that prominent in the US, but In Europe, it is a very popular choice for local brewers to make beer that harkens back to their family roots. It works great in most European Lagers as well as most American Ales.

Aurora 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.
|7% – 12%|
|Beta Acid %|
Beta acids are what give hops their more aroma and flavor compounds.
|2.7% – 5%|
This ratio of alpha acids to beta acids determines how quickly bitterness fades during aging. Lower ratios are common for aromatic varieties.
|1:1 – 5:1|
|Co-Humulone as a % of Alpha|
Higher numbers are said to impart a harsher bitterness.
|22% – 26%|
|Total Oils (mL/100g)|
With more total oils, typically comes a more complex hop profile but these are highly volatile compounds.
|0.9mL – 1.8mL|
|17% – 25%|
|5% – 9%|
|5% – 10%|
|Other Oils: Includes beta-ionine, beta-pinene, limonene, linalool, geranoil & selinene||31% – 49%|
|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 72% of its alpha acid after 6 months of storage at 20ºC (68ºF).|
|Hop Storage Index (HSI) Rating||Good|
Aurora 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 Aurora, we recommend substituting with the following hops:
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 Aurora for IPA, New England IPA, Pale Ale, Wheat Beer, Golden Ale. That being said, experiment and see what works best for you.
