This application will enable you to check the authenticity of your bottles of Château Margaux, Pavillon Rouge du Château Margaux, Margaux du Château Margaux and Pavillon Blanc du Château Margaux, as soon as these have been equipped with the bubble code security system.

Instructions for authentification :
- Enter the bubble code indicated on your bottle and click on the magnifier.
- Compare the position of the bubbles that appear on your Smartphone with that of the seal on your bottle.
- Discover the tasting note corresponding to your wine, as well as the weather conditions for that vintage.

Conditions :
- Your bottles must have been labelled on or after 7th March 2011
