Mauricio, i think you're misreading the Compendium charts. That chart refers to Meunier's overall plantings in Champagne, not just in Marne. Within Marne, it occupies nearly 2/3rds of the vineyards. Marne is cold (as is Champagne in general) and prone to frost, but Meunier buds late, making it more reliable in Marne for areas that don't have the exposure/topography to avoid frost and/or ripen Pinot Noir effectively.
In the Guild Somm video about Champagne and within the regions of Champagne subsection, it describes Pinot meunier as the major grape for Vallee de la Marne. In the compendium it has it at low percentage planting. Any reason why that might be?
Jessie, I don't know that it was an official change so much as it was an acknowledgement of the Champagne region overall simply calling it Meunier. This is highlighted in Peter Liem's new book on Champagne. Admin User could offer a better explanation I'm sure!
