Barley Malting Process – Production Regimes Flashcards
What is the primary reason speciality malts have a higher colour than pale malts?
They have spent more time at high temperatures in the kiln or roasting drum.
What additional benefit do speciality malts provide besides increased colour?
More flavour.
What is the source material for all speciality malts?
Green malt.
How are some speciality malts produced compared to others?
One group is made using high temperature kilning followed by roasting, while the other is produced by stewing then roasting.
What type of barley is commonly used for many speciality malts?
Higher nitrogen barley.
What reaction is enhanced by the availability of nitrogen in malt production?
The Maillard reaction.
What happens to a malt’s diastatic power as its colour increases?
The diastatic power decreases.
What is the maximum temperature during the drying process for pale malt?
70˚C.
What is the purpose of increasing the temperature during curing of pale malt?
To convert more SMM to DMS and evaporate the DMS that is formed.
What is enzymatic malt produced from?
High nitrogen barley.
At what typical temperature is the kilning of enzymatic malt completed?
Does not typically exceed 50°C.
What is chit malt characterized by?
Barely modified.
What moisture level is used for germinating chit malt?
40% moisture.
What problems can arise from using chit malt above a few percent?
Wort separation problems.
What is dextrin malt primarily sold as a source of?
Dextrins.
What is a common misunderstanding about dextrin malt?
Some are higher in protein and contribute to body rather than providing dextrins.
What is the effect of using certain dextrin malts instead of base malt?
More unfermentable extract remains after saccharification.
Fill in the blank: The greater availability of nitrogen can increase colour and flavour formation through the _______.
Maillard reaction.
True or False: Higher curing temperatures in pale malt production are intended to enhance enzyme activity.
False.
What type of malt is produced using lower temperatures during germination to conserve enzymes?
Enzymatic malt.
