Features & Benefits
- Product Highlights
- Hop Oil – Type NOBLE PLUS is produced from conventional hop extracts which are subsequently fractionated by means of CO2 extraction to enrich or decrease the concentration of specific aroma compounds.
- Hop Oil – Type NOBLE PLUS has been specifically developed for additions prior to filtration. This product can completely or partially replace late hop additions in the brewhouse while still imparting a typical “late hop” aroma to the beer.
- Hop oil recovery is considerably higher compared to conventional hopping methods, as the aroma compounds are not lost due to evaporation in the brewhouse.

- Product Information
- Appearance
Hop Oil – Type NOBLE PLUS is a nearly colorless, clear liquid containing hop essential oils.
- Flavor
Hop Oil – Type NOBLE PLUS contains a lower amount of the undesirable volatile hydrocarbon fraction, resulting in a more subtle and pleasant hop aroma. Depending on the quantity added and the type of beer, Hop Oil – Type NOBLE PLUS can impart floral, spicy and citrusy notes to beer.
In addition, Hop Oil – Type NOBLE PLUS has little influence on the sensory bitterness of beer.
It is suitable for use in beers brewed with conventional hop products as well as light stable beers to impart a more typical “late hop” character.
• Recovery
Hop Oil – Type NOBLE PLUS contains fewer volatile hop compounds and therefore excellent recovery rates are possible. Depending on the time of the addition, the recovery rate for hop oil can be as high as 95 %.
• Quality
All Hopsteiner® products are processed in facilities which fulfill internationally recognized quality standards.

• Dosage
Hop Oil – Type NOBLE PLUS is supplied as a 1:100 dilution in propylene glycol. The quantity of the hop oil addition is determined by the brewer and depends on the time and point of the addition. The hop oil dosage should be based on the desired concentration of linalool in the beer, which typically ranges from 20 µg/l to 100 µg/l. These concentrations are intended for orientation only; actual additions will depend on the quality and intensity of the aroma desired. Trials performed by injecting oil into filtered beer (bright beer) with a microliter syringe are helpful for determining the quantity of hop oil required.
Dosage example for a 1:100 dilution of hop oil, based on a yield of 90 %*:
1.1 ml/hl results in 20 µg/l linalool in beer
5.5 ml/hl results in 100 µg/l linalool in beer
*can vary from brewery to brewery
• Addition
Hop Oil – Type NOBLE PLUS can be added at different stages on the cold side of beer production, typically prior to filtration. For the highest possible yield, a direct addition into the beer stream prior to filtration is recommended. This enables the hop oils to dissolve in the beer without changing their flavor.
