5.  With the aid of time vs. temperature graphs, compare an ale type kilning profile with a high diastatic malt type kilning profile.  Discuss the relevance of any differences.

6.  Describe the co-products streams from a malting plant with barley intake and drying facilities.  Include in your answer typical co-product analytical parameters and anticipated values.

7.  Describe the method of manufacture of dark crystal malt.
