HardResin Pellets


HardResin Pellets are a hop product made from leaf hops, added to the wort kettle during the boiling process. They impart a smooth bitterness and mouthfeel to beer.

HardResin Pellets can release glycosidically bound hop compounds to impart a pleasant hop aroma to beer.

HardResin Pellets are rich in antioxidative polyphenols.

HardResin Pellets are pale yellow-green pellets, approximately 8 mm x 10 - 25 mm in size (diameter x length). 


HardResin Pellets produce a smooth bitterness. The hard resins and polyphenols in the pellets have been shown to contribute to improved mouthfeel and overall beer flavor. Moreover, key flavor compounds (e.g. linalool) released from hop glycosides produce a pleasant hop aroma.


All Hopsteiner® products are processed in facilities which fulfill internationally recognized quality standards. A monitoring system for residues is in place.


Our products are delivered in their respective recommended standard packaging. Alternatives may be possible upon customer request.
Standard packages of our processing plants in the USA (US) and Germany (DE) are:

  • softpack under inert gas in 5-layer aluminum composite foils (US / DE)

Suitable pack sizes are available on request.


HardResin Pellets are employed to enhance the quality of the bitterness and to increase mouthfeel. HardResin Pellets also improve the physical stability of the finished beer through the precipitation of undesirable proteins.


The quantity of HardResin Pellets added to the wort kettle depends on the application and will vary according to the raw materials and other hop products used in the brewing process. They can be added at any time during the boil. To determine their impact on beer flavor, brewing trials are recommended as the quality and quantity of the compounds imparting the bitterness, aroma and flavor (the latter are released from the hop glycosides) will vary among varieties. Typical additions range from 20 to 100 g/hl.


HardResin Pellets can be manually weighed out and added directly to the wort. Alternatively, owing to their free-flowing nature, additions of HardResin Pellets can be automated.


The recommended storage temperature in the original unopened packaging is  < 5 °C (41 °F).

Short-term, transport-related temperature deviations do not affect product quality.

Best Before Date

Under the recommended storage conditions, the shelf life from the date of production/ packaging is at least 5 years.
