Abstract
THE taste of distilled water has been shown to depend on previous adaptation1–5. In studies where an exact description of purity is necessary, only the number of distillations are quoted, which is inadequate because purity varies with distillation efficiency. Measures such as specific conductivity for ionic impurities and surface tension for surfactants are better indications of purity. Variation in tapwater solutes makes it possible to distinguish samples by taste so that the same criterion may be true for purity variations in distilled water. This was tested here using once and twice distilled water.
