Bi‐plot of PCA based on the chemical characterization of untreated barley and barley malt. The positions for untreated (*) samples and each steeping condition (for details see Table 1) are shown and related to the chemical characteristics measured (Inline graphic).Data points belonging to the same group are within the marked areas. The data are grouped according to the barley variety (Tipple Inline graphic, Karmosé Inline graphic, Cinnamon Inline graphic). The arrows show the change in chemical characteristics from untreated material to malt of each barley variety.
