Martell Cordon Bleu Extra Cognac is a new take on an old favorite, with some subtle differences. The first is the age of the cognac. The normal Cordon Bleu is an XO quality, but, as the name suggests, this new model is an Extra Cognac. Whilst it still has a lot in common with the original Cordon Bleu blend (a large proportion of Borderies eaux-de-vie and candied fruit aromas), this brand new product delights with its depth and taste sensations.
