Astra Hop Oil Breakdown

Hop oils can vary 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% – 10%
Beta Acid %
Beta acids are what give hops their more aroma and flavor compounds.
4% – 6%
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.
1:1 – 3:1
Co-Humulone as a % of Alpha
Higher numbers are said to impart a harsher bitterness.
26% – 28%
Total Oils (mL/100g)
With more total oils, typically comes a more complex hop profile but these are highly volatile compounds.
1mL – 3mL
Myrcene
green, resinous
Data Not Available
Humulene
woody, piney
6% – 8%
Caryophyllene
woody
Data Not Available
Farnesene
floral
Data Not Available
Other Oils: Includes beta-ionine, beta-pinene, limonene, linalool, geranoil & selinene92% – 94%
Hop Storage Index (HSI)

Astra 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 Astra, 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 Astra hops for Pale Ale, IPA, American Lagers, Saison, and Farmhouse. That being said, experiment and see what works best for you.
