Grower Champagne

Growers Champagne in Australia
Grower Champagnes are Champagnes produced by the estate that owns the vineyards where the grapes are grown. Récoltant-Manipulant is the term in French, and Grower Champagnes can be identified by "RM" on the wine label.
While large Champagne houses such as Mumm, Moët et Chandon and Veuve Clicquot may use grapes from as many as 80 different vineyards in the Champagne region to create a consistent house style, Grower Champagnes tend to be more terroir-focused, sourced from a single vineyard or closely located vineyards around a village, and made with grapes which vary with each vintage. 
Today there are over 19,000 independent growers in the Champagne region, accounting for nearly 88% of vineyard land in the region; around 5,000 of these growers produce wine from their own grapes.
