Quality Assesment Flashcards
What is one quality check that can be carried out during germination?
Moisture content analysis
This is crucial for assessing the hydration level of the grains.
What does acrospire growth indicate?
It indicates the progress of germination.
Acrospire growth is a key factor in evaluating the germination process.
What does visual analysis involve?
Rubbing grains between your thumb and forefinger.
This method helps assess the modification of the malt.
What does it mean if the starchy endosperm appears chalky on your fingers?
The malt is correctly modified.
This indicates proper germination and modification of the grain.
What happens if cell wall material is present when rubbing grains?
It forms little balls, indicating the malt is under modified.
Under modification can lead to processing issues.
How long does barley typically spend in the germination vessel?
Four to six days.
This duration is essential for proper germination.
What can over modification of grains reduce?
Extract levels.
Over modification leads to loss of starch to embryo growth.
What issue can arise from the friable nature of over modified grain?
Shattering leading to dust losses.
This can result in finer grist than required for wort separation.
What problems can under modified grain cause in the brewhouse?
Problems in filtration due to undegraded β-glucans.
Undegraded β-glucans can hinder the brewing process.
What continues during the first couple of hours of kilning?
Modification of the grain.
This indicates that the process of change in the grain continues even after germination.
Fill in the blank: The term used for the batch at the end of germination is _______.
green malt
Green malt signifies the stage of the grain before it is transferred to the kiln.
