Potentiometric responses of porphyrin-based solvent polymeric membranes towards several aliphatic monatomic alcohols in single-, two- and four-component solutions were evaluated. Sensitivity of membranes in single-component alcohol solutions decreased in the following order: ethanol > methanol > isobutyl alcohol. A performance of potentiometric porphyrin-based Electronic tongue (ET) for analysis of alcoholic beverages is described. The utility of ET system for an identification of beverages made of two different source materials: grape and barley has been shown. Simultaneously a scale of beverages’ ‘alcoholic degree’ in ethanol concentration units was evolved. The alcoholic strength of several commercial sorts of wine, beers, grappa and whiskey was successfully evaluated according to the evolved scale.
