Pellets Type 90


Pellets Type 90 are a hop product made from leaf hops, added to the wort kettle during the boiling process. Depending on the time of the addition, these pellets contribute to the desired bitterness as well as to the characteristic hop aroma of beer.

Pellets Type 90 are also suitable for use on the cold side (dry hopping) of the brewing process. They impart a pronounced hop aroma to beer.

Pellets Type 90 have a composition very similar to that of leaf hops, but deliver higher yields, more consistent quality and improved storage stability. The costs for storage and transportation are also lower.


Short description
cylindrical hop pellets; mechanically produced from milled leaf hops of a certain variety
Alpha acids
1 - 25 %
Beta acids
1 - 24 %
Hop oils
0.2 - 4.5 ml/100 g
Moisture content
6 - 9 %



Pellets Type 90 are olive green pellets, approximately 6 mm x 10 - 15 mm in size (diameter x length). 


Pellets Type 90 Pellets produce flavors in beer indistinguishable from those of leaf hops. Pellets Type 90 provide bitterness and aroma to the beer. The flavor depends on the variety, quantity and time of addition. For further information, please refer to the Hopsteiner® variety data sheets.


Given as an early kettle addition (up to 15 min after the boil begins), hop utilization normally falls within a range of 30 - 35 %. When Pellets Type 90 are added late in the boil, utilization can decline to 20 % or less, depending on individual process conditions. Both additions can vary depending on the desired intensity and the beer style.


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:

  • 5, 10, 90, 140 kg softpack under inert gas in 5-layer aluminum composite foils (DE)
  • 20 kg soft pack under inert gas in 5-layer aluminum composite foils (US)



The quantity of Pellets Type 90 in an addition can be calculated using the alpha acid content of the pellets and an estimated or known utilization. Late kettle additions of Pellets Type 90 (typically 5 - 20 min prior to the end of the boil) reduce alpha acid utilization but increase hop aroma and flavor.


Pellets Type 90 can be added directly to the wort kettle or hop dosing vessel. Alternatively, owing to their free-flowing nature, additions of Pellets Type 90 can be automated. Dry hopping normally involves the addition of Pellets Type 90 during secondary fermentation or maturation using various techniques.


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.


Ensure good ventilation of the workplace and wear personal protective equipment. Avoid contact with eyes and skin. Do not inhale vapors or dusts. For full safety information, please refer to the relevant Hopsteiner® safety data sheet.
