Before bottling, each wine is thoroughly homogenized in a large blending vat, ensuring that exactly the same wine is in all the bottles. As in the other stages of the maturing process, very strict health controls and traceability procedures are observed during bottling. This usually starts in the middle of June with the Pauillac, followed by Les Forts de Latour and the Château Latour. The corks are subjected to strict selection when purchased, and then checked again manually before being used in the bottling process. The bottles are not labelled and put into wooden cases until they are shipped in order to ensure perfect presentation. Each bottle is carefully wrapped by hand in white tissue paper bearing the Latour signature to provide optimum protection for the labels. An innovative and highly efficient special traceability and authentication system was introduced with the 2007 vintage that is directly visible on the bottles.
