In the present study, the effect of the curing temperature during kilning on the concentration of bDam in malt was monitored, as well as during mashing and wort boiling. Two different varieties of malt (spring and winter) were compared. The results showed different trends during malt kilning, with an increase in the levels of the aroma compound over time at 78 and 90 °C. During mashing and wort boiling, bDam was formed following different trends, this attributed to a balance between formation and evaporation. Moreover, malts and worts from winter barley contained more bDam than spring barley. Further research is required in order to identify and monitor the precursors of this potent aroma compound.
