Contamination of beverages, particularly alcoholic drinks with toxic methanol still appears as a fatal issue in the world. While quantification of the methanol content in a beverage sample is typically conducted through the authorized protocols by using GC or HPLC, materials that allow the discrimination of risky beverages in a simple manner could be still attractive under certain circumstances. Here we report an amino-acid based molecule (1)1 whose solvent-specific phase-transition behavior allows to visually detect the presence of methanol over the level of regulatory limit in alcoholic drinks (0.1 % according to FDA in USA and MHLW in Japan).
