Composition |
T-90: |
as for leaf hops except: |
| - |
slightly lower moisture content |
| - |
resin glands are ruptured and lupulin is spread over particles |
|
T-45: |
| - |
about 40 - 50% of the plant vegetable matter is removed |
| - |
resin/oil concentration is virtually doubled |
|
|
| Intermediate enrichment grades between T-90 and T-45 are available more or less upon request. |
|
|
Advantages |
|
| - |
significant volume reduction from leaf hops enhanced further under enrichment, leads to ease of shipping, handling and disposal |
| - |
packaging methods improve storage stability |
| - |
standardization of product is easy so better control of bitterness |
|
| - |
utilization of bitterness is enhanced (30-35%) |
| - |
cost of iso alpha-acids in beer is similar to leaf hops |
|
Disadvantages |
| - |
products still bulky compared to extracts |
| - |
possible contamination with pesticides, nitrates, radioactivity and dust |
| - |
wort losses compared with extracts |
| - |
modified behaviour in brewing process |
