Characterisation of tequila according to their major volatile composition using multilayer perceptron neural networks

► Higher alcohols and furaldehydes as chemical descriptors to differentiate tequilas. ► Higher alcohols were determined by HS-SPME-GC-MS. ► Furaldehydes were determined by HPLC. ► BP-MLP-ANN allows complete differentiation between aged and not aged tequilas.
