XO cognacs must be aged a minimum of six years, although many producers use much older spirits in their assemblages. XO cognacs benefit from this extended wood ageing, and are generally extremely smooth and rich in flavour. This means they are unsuitable for all but the most premium cocktails and are generally best served neat after a good meal.
A 3 litre bottle of Martell XO. Containing cognacs of up to 35 years old, this is a perfect example of blending. It combines the elegance and nuttiness of spirit from the Borderies combined with power from the Grande Champagne region.
