How do you get a darker-colored malt?

• A. Kilning for a longer time
• B. Roasting at a higher heat
• C. Steeping longer
• D. Adding caramel malt

Answer: (A)

Color in malt comes from heat-driven reactions that happen during the kilning phase after germination. As the grain is dried and heated, sugars and proteins interact in Maillard reactions and some caramelization occurs. The longer the malt stays in that heated environment, the more of these reactions occur, producing darker pigments and deeper flavors. So extending the kilning time pushes the malt toward a darker color. Steeping longer doesn’t increase color; it mainly affects hydration and the start of germination. Adding caramel malt would darken the overall mash, but that’s introducing a pre-darkened ingredient rather than darkening the base malt through the malting process itself. Higher heat in roasting can create darker malts, but the straightforward way to achieve a darker color during malting is to prolong the kilning period.
