BETA FRACTION
|
Purpose: |
Beta fraction can be added to the kettle if necessary to control and normalise boiling characteristics, where a greater part of the hop grist is added via isomerised products. It may also be added just before the end of boil to impart hop aroma. |
|
Description: |
Derived from Pure Resin Extract and contains most components, such as essential oils, fats, waxes and beta acid. The actual composition depends upon hop variety. |
|
Analysis: |
Contains approximately 4% - 20% essential oils, 30% - 60% beta acid, the remainder is mostly soft resins, <5% water, <5% iso-alpha acid. |
|
Packaging: |
Typically 200 kg drums, other sizes can be specified. |
|
Product Use: |
If used to control boil characteristics or to provide non iso-alpha acid derived hop flavour, the Beta fraction is added at the kettle at the commencement of boil. For hop aroma characteristics the extract is added just before cast/kettle transfer. Actual dosages depend on many factors, but particularly on the intensity and type of hop aroma desired. Wigan Products Ltd would be pleased to advise on specific enquiries. |
|
Storage: |
Stable for at least two years if kept unopened in the original packaging at 3 - 6oC. |
