Results are stated summing up the data of experimental verification of the technique used for determining the alcoholic stength in tinctures. Propose three methods for determining alcohol in tinctures (method distillation, method G. K. Koliakova and method P. Balovoine). Experiments showed, that the best method for determination of ethanol concentration in the tincture is the method of P. Balovoine based on dry residue and relative density.
