(TDB) - We bring you all the latest stats and facts about the world’s 10 biggest Champagne brands, ranked according to global volume sales.

Over the following pages is the definitive guide to the best-selling Champagne brands in the world, which we’ve ordered according to volume sales during the course of 2015.

We have placed a particular focus on the components of these major Brut Non Vintage blends, with information on the dosages, lees ageing times and proportion of reserve wines in today’s releases of the top 10 biggest Champagnes.

We have also brought you news on the latest product launches and marketing initiatives from each of the houses behind these big-hitting brands.

Champagne’s best sellers aren’t just focused on boosting sales volumes, and we’ve looked at quality improvements over recent years, motivated by the need to compete with each other, as well as sparkling wines from outside Champagne.

To improve the taste, Champagne’s major producers are focused on augmenting the quality of the grapes used to make their big-volume cuvées, as well as updating the winemaking methods. Bringing a notable increase in the complexity and depth of flavour has been the decision by these leading producers to increase the amount of reserve wine employed in their blends, along with a move to extend lees-ageing times – which brings more toasty flavours.
