There are no data available to establish accuracy/trueness of the submitted method using some certified or standard reference materials (SRM) with known ethanol concentrations. It is possible because currently there are commercially available SRM for Kombucha Tea matrix. It will help if the method accuracy could be demonstrated using other relevant reference materials like BCR 651 (Beer, ethanol = 0.505%), BCR 652 (Beer, ethanol = 0.051%).
