Callista hops are a newer variety developed at the Hop Research Center in Hüll, Germany. Callista hops were bred and developed in Germany, with parentage from Hallertau Tradition and a male breeding line. The name Callista has many meanings, but it is mainly referred to as meaning “most beautiful (feminine)” in Greek. They were formerly named 2010/008/033 during trials and have been made available since 2016.
Callista hops have a mild alpha range, which means they are not very bitter but have an outstanding aroma and are packed with fruity flavors. The hop’s aroma is best used in beer brewing for late-boil or dry hop additions.
Callista hops are known for their intense fruit flavors, including stone fruits such as apricot and peach, red berries, and passion fruit. This variety of hops is excellent for delicate beer styles like pilsners and for adding fruity flavors to pale ales and IPAs.

Where To Buy Callista Hops
Callista Flavor And Aroma
Callista is an aroma hop that is often described to have the following aroma characteristics:
Callista 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.
|2% – 5%|
|Beta Acid %|
Beta acids are what give hops their more aroma and flavor compounds.
|4% – 9%|
This ratio of alpha acids to beta acids determines how quickly bitterness fades during aging. Lower ratios are common for aromatic varieties.
|0:1 – 1:1|
|Co-Humulone as a % of Alpha|
Higher numbers are said to impart a harsher bitterness.
|15% – 22%|
|Total Oils (mL/100g)|
With more total oils, typically comes a more complex hop profile but these are highly volatile compounds.
|1.5mL – 2.0mL|
|63% – 64%|
|Other Oils: Includes beta-ionine, beta-pinene, limonene, linalool, geranoil & selinene||36% – 37%|
|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).

Callista 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 Callista, 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 Callista for IPA, New England IPA, Pale Ale, Wheat Beer, Golden Ale. That being said, experiment and see what works best for you.
