What are the three important outcomes of heating or kilning barley after germination?

The correct choice highlights three key outcomes of the kilning process involved in malt production.

Halting germination is crucial, as it stops the enzymatic processes initiated during germination, preventing the grain from sprouting further. This halting of germination is critical because maltsters need to control the development of enzymes that will later convert starches into fermentable sugars during the brewing process. If germination continues, it can affect the quality and characteristics of the malt.

Drying the malt serves to reduce moisture content, which is essential for preventing spoilage during storage. Proper drying also allows the malt to be processed further without the risk of mold development or spoilage.

Adding color occurs through the Maillard reaction and caramelization as the grains are heated during kilning, which can influence the beer's final color as well as its overall flavor profile. Different temperatures and durations can produce various color levels, thus giving brewers the ability to achieve desired characteristics in the finished product.

Together, these outcomes significantly affect the quality of the malt, enriching the brewing process and the eventual beer produced.
