Bobek hops are a diploid hybrid hop variety bred in Slovenia’s Zalec region alongside Blisk and Buket. It was created to combine high alpha acids and a pleasing aroma in one cultivar. Bobek is not being commercially produced at the moment. Its parents are Northern Brewer and a Slovenian male.
Bobek hops are known for their pleasant floral aroma, and they are also noted for their excellent agronomic properties. Bobek has distinct notes of lemon, and grapefruit, green aromas like tomato leaves, sage, and artichoke, and woody and vegetal elements like hay.

Where To Buy Bobek Hops
Bobek Flavor And Aroma
Bobek is a dual-purpose hop that is often described to have the following aroma characteristics:
Bobek 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.
|3.5% – 9.3%|
|Beta Acid %|
Beta acids are what give hops their more aroma and flavor compounds.
|4% – 6.6%|
This ratio of alpha acids to beta acids determines how quickly bitterness fades during aging. Lower ratios are common for aromatic varieties.
|1:1 – 2:1|
|Co-Humulone as a % of Alpha|
Higher numbers are said to impart a harsher bitterness.
|26% – 31%|
|Total Oils (mL/100g)|
With more total oils, typically comes a more complex hop profile but these are highly volatile compounds.
|0.7mL – 4mL|
|30% – 63%|
|12% – 19%|
|4% – 6%|
|3% – 7%|
|Other Oils: Includes beta-ionine, beta-pinene, limonene, linalool, geranoil & selinene||23% – 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).

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