Back Braille, named after its inventor, is a raised-letter writing system for the blind. An exclusive feature of the M. Chapoutier estates in Tain l'Hermitage, which has been reproducing all its labels in Braille since 1997. This generous contribution to blind customers is a brilliant idea that has been very well received by the general public and the specialist press. Printing Braille on the entire M. Chapoutier range presents a number of technical challenges: printing raised letters requires the use of special quality paper, the characters must be of a minimum size and the bottles must be positioned in the boxes in such a way that the raised printing is not crushed.
