Abstract: Eight different sorts of malt beverages were collected from the local markets of western province of Saudi Arabia. The studied samples were subjected to the determination of physicochemical Characteristics such as pH, conductivity and TDS. Also, the concentration of 15 major and trace elements has been determined using inductively coupled plasma-atomic emission spectrometry. The levels of all investigated elements were below the maximum tolerance levels reported by international regulatory standard. The beverages were tested quantitatively by capillary gas chromatography for their alcohol content through three steps. Firstly, the studied samples were directly analyzed, secondary, the samples were analyzed after exposing to air and finally the samples were analyzed in presence of yeast. It has been found that there is no ethanol content when the samples analyzed directly, minor concentration of ethanol content was found after exposing malt beverages to air ranging from 12.7 ppm in Hillsgurg to 1940.6 ppm in Efes. Considerable variability in the alcoholic strength was found in presence of yeast due to fermentation, overall, the range of concentrations was 0.4621 Vol % in Budwisers to 3.416 Vol % in Hillsgurg.
