Abstract G.S.M. Blue is composed primarily of water, sugar cane alcohol with essences of juniper berries and other botanicals with traces of impurities and flavourings and it has 32.5 percent alcohol by volume (65 proof). The experiment aimed to separate its components, alcohol and water, and to determine its percent concentration of ethanol by using the Fractional distillation method. A certain volume (25 mL) of G.S.M. Blue was placed on the distillation set-up and was heated constantly. A certain volume (1.o mL) of distillate was collected in every test tube until the temperature reached close to 95-97 oC. The volume of distillate collected by the end of the distillation was 14.0mL at 95 oC, giving a percent alcohol of 71.43% and 4.0% loss.
Introduction In general, beverages may be simply defined as any drink which can relieve thirst, nourish the body, stimulate the appetite or increase the amount of body fluids. These may be classified as Alcoholic or non-alcoholic. Alcoholic beverages have made an inescapable presence in our culture for centuries either for its hygienic, medical, or recreational purposes. Alcoholic beverages are liquids produced from the alcoholic fermentation of fruits or grains [1]. The sample used in the experiment, G.S.M. BLUE, is a 65 proof, sugar cane alcohol with essences of juniper berries and other botanicals. Its smooth, sweet taste gives drinkers a “light-on-the-chest” feeling without hangover.
Distillation is the separation of a liquid mixture into its components on the basis of difference in boiling points. The liquid is changed into a vapour by boiling. The vapour is pure as other substances are left behind. The vapour is then cooled. It condenses to a pure liquid which is called the
