Features & Benefits
- Product Highlights
Hop Oil – Type DRY is produced from leaf hops and contains the complete range of essential oils found in them.
Hop Oil – Type DRY can be added at various points in the brewing process (typically on the cold side of production) and results in improved aroma yields compared to traditional hopping techniques.
Hop Oil – Type DRY imparts a typical dry-hopped aroma which varies depending on the time of the addition.
- Product Information
- Appearance
Hop Oil – Type DRY is a nearly colorless, clear liquid, containing the complete range of hop essential oils.
- Utilization
Depending on the time and point of the addition, the recovery rate for hop oil can be as high as 95 %. Actual utilization will vary from brewery to brewery due to differences in equipment and process conditions.
• Flavor
Hop Oil – Type DRY can be used to provide a strong hop aroma, or alternatively, a more subtle hop aroma depending on the quantity added as well as the time and point of the addition.
The intensity of the bitterness might increase depending on the quantity added.
• Quality

- Product Use
• Dosage
The required quantity of Hop Oil – Type DRY diluted to 1:100 (see Packaging section) depends on the point of the addition:
Pre-fermentation: up to 500 g per hl Maturation tank: 50 – 300 g per hl Prior to filtration: 1 – 20 g per hl
The dosage rates above are intended for orientation only; actual additions will depend on the intensity of the aroma desired. Trials performed by injecting oil into the beer with a microliter syringe are helpful for determining the quantity of hop oil required.
• Addition
Hop Oil – Type DRY can be added at different stages of beer production. Dosing equipment which pumps the product into the beer stream is preferred for the addition of Hop Oil – Type DRY. Alternatively, the hop oil can be added to the tank prior to filling.
-
- Pre-fermentation: the loss of volatile compounds during fermentation, combined with the biochemical modification of aroma compounds by yeast, can produce a less grassy aroma.
-
- Maturation tank: additions to the maturation tank will result in slight changes to the hop aroma, due to yeast activity.
-
- Prior to filtration: direct additions result in an almost unchanged flavor. However, there are certain losses of non-polar compounds.
